Canon has published a product advisory notice acknowledging the existence of a 'light leak' issue on the EOS 5D Mark III. Users of the camera have reported that in dark conditions, switching on the top-LCD's back-illumination or shining a light on it alters the camera's metering, suggesting light is leaking into the body and reaching the metering sensor. The company says it is investigating the problem and possible countermeasures, and will make further announcements once a decision has been made on resolving the issue. The full advisory note is on the Canon USA website. Petapixel reported on the issue and has linked to user videos which illustrate the problem.

Light leak issue is actually not a problem, until canon usa made it a big problem by issuing a stupid statement by revealing the serial number that are affected without having the initiative to recall those serial numbers and replace them with the one that have been modified. For canon user, this is the biggest problem that you should be furious about.... think about the resale value of your camera with that serial number, yeah they will fix it, i know that too, but for some freaks.. the camera that has been opened will suffer from a lower resale value!!! Stupid Canon USA..... !!!! Dumb ass!!!! dont u guys out there still have a brain???? y people with the serial number of 1 and 2 have to bear all the consequences, when they are proven to be a loyal canon customer for adopting a new model. And they have to pay for that????? STupid Company policy, may be their brain freeze after the tsunami!!!

Hi everyone,

May be someone can help me on this.
I got a 5D Mark 3 a couple of days ago, read the light leak issue and decided to give it a try just to see.
This is what I did:

Test 1:
Room completely nearly dark (98%).
Using live view in A+ mode, LENS CAP NOT ON LENS
- Took a shot, F1.2 at 1/20s.
- Then took a shot again + switch the top LCD light ON, got F1.2 at 1/20s.

I was actually surprised that my AF could pick a picture on the wall in near total darkness using live view... may be I don't keep up to date with things enough.

Test 2:
Room completely nearly dark (98%).
Using live view in A+ mode, LENS CAP ON LENS.
- Took a shot 0.5s at F1.2.
- Took another shot + switch the top LCD light ON, got 0.5s at F1.2.

So, what am I missing...? Looks to me that it's all good.
I someone could provide some infos on this it will be much appreciated...

Cheers.

Spoke with Canon USA and Canon Japan. According to the representives, the answer is NO. No modifications will be made to the Camera body both internal and externally for now nor in the future. Current stocks that are in the pipelines to be sent out to the retail stores will continue to have xxxxx1, xxxxx2, xxxxx3, and so on with no modications since this "PROBLEM" is not really a problem to begin with. And as Canon stated on their Website, There is no RECALL on this "issue" to be fixed.
But Canon will be more than happy to take a look at those customers who are stil paranoid beginning Mid-May.

The light Leak DOES affect the images. The faulty metering causes some images to be underexposed. Imagine a scene on the limit between two exposure levels. The light leak will then cause the scene to be exposed at the lower level. This will happen at ALL LIGHT LEVELS! Furthermore, in some situations, the light leaking onto the meter through the LCD screen will cause the image to be underexposed several steps. For example, I recently used a 10 stop ND grad to blur the water in a waterfall on a sunny day. In that situation, the sunlight leaking in through the screen is relatively large compared to the scene (as seen through the filter). The result was an image underexposed by many steps, and the images came out completely black. So the statement from Canon indicating that the leak does not affect the captured images is NOT TRUE..

Have you tried it??? dont say for example,... if you havent tried it on your own.....cuz I have already tried it, the metering doesnt change! the metering range for canon 5d markIII is between ev1-ev20.. read your manual again..... underexposed several step?????? you dont even know what you are talking about..... , the most under very extreme condition it goes underexpose by 2/3 of a stop... several step????????? Are you talking about your stair at home????? Step????? Sunny day is around ev 15, and you reduce it by 10 stops using ND filter its gonna become ev 5!!! at ev 5... the metering doesnt change, I tried that with 1000 watts hot light shinging on the top lcd, I believe its brighter than sunlight!!!..... again DOES NOT CHANGE!!!!! so please make sure that you have already tried it.. before making any comments

I didn't just theorize it, I tested it. 14.8 EV @ ISO 100, using a B+W 10 stop ND filter on the EF 24mm F/1.4L Mark II lens.

Both shaded and covering the LCD did not give me any metering errors or any exposure issues.

There are more then 250 comments posted on this light leak issue, so obviously there is a problem. All my lenses and camera's are Canon and I just bought the Mark III. What I find rediculous about it all is the way a reputable manufacturer like Canon handles an engineering fault. If Canon where a car manufacturer they would recall all related models and fix the problem. I didn't pay $3000 + for a piece of equipment to have to put duct tape on the inside of an LCD screen, as suggested by some. Canon is responsible for their mistakes and should fix it, simple.

What do you mean how they are handling this? Do you have inside information on how they are going to repair the issue which they have issued will happen for all users within a serial number range that they clearly identified and are going to provide free support and service over. (http://usa.canon.com/cusa/professional/products/professional_cameras/digital_slr_cameras/eos_5d_mark_iii?pageKeyCode=prdAdvDetail&docId=0901e02480538fc7)

I wasn't aware that anyone in the 250+ useful comments had made any serious suggestions of duct tape. I think black nail polish is better.

I guess it seems very irresponsible for them to act in a timely manner with the problem identified about 2 weeks ago, and now they have provided a solution to resolve this. Boo Canon!

Wow if this is what you think of Canon, I'd hate to see how you'd respond to Nikon's current issues and denials: (http://nikonrumors.com/2012/04/21/nikon-claims-that-the-greenish-d4d800-lcd-screen-is-more-accurate-than-the-d3sd700.aspx/)

Stanley Zheng, No body asked me to put duct tape, someone wrote that he put some duct tape on the inside of his LCD screen, which I don't want to do when I buy an expensive piece of equipment. To me it doesn't matter if the fault is small or big, a fault is a fault and Canon should fix it. 1/3, 1/2 or 3 steps or stops, which ever you prefer, is just not acceptable in my view. To your question what there is to be fixed? It is what Canon themselves call a "Light Leak", that is all, sounds like contradiction to me, photography and leaking light. Cheers and have fun anyway.

**Puts hand up**

I'm the guilty party suggesting to open up the camera and stick some black duct-tape underneath the LCD panel.

To be honest, I did say that slightly in a tongue-in-cheek tone. Also waaaay back then when I made comment, it was not yet apparent that the metering was *only* affected with the lens cap on (thanks to various people posting results of tests right here).

No one to my knowledge on these forums has experienced the problem with the lens cap off: daytime or nighttime exposure.

I'm a Canon user for many years and came here to find out more about this issue for when I finally decide to upgrade to the 5DIII.

I also read in the manual book under specification, exposure control on page 374 , it is clearly stated that the metering range from ev1 - ev20, at ev1 there is no effect whatsoever on the metering value when you turn on the lcd back light. Thus, its pretty clear that this camera is not build to meter anything below ev1 accurately, so I dont think its a defect...

@Kinematic Digit and others, thanks for providing the results of all your tests. Based on your findings I think we can summarize the issue as this:

(1) - There is a very minor light leak issue through the top LCD, *but* it is only evident with the lens cap on. To date, no one has been able to replicate the problem with the lens cap off... yay! :)

(2) - Daylight exposures are not affected in any way at all.

(3) - Night time exposures are also not affected. Even when exposing for a very dark subject, shining a light on the top LCD or engaging the back-light has no effect on exposure.

If my understanding is flawed, please correct me and provide details about your test.

I dont know if this is a valid argument, but if and only if let say there is a light leaking, then if you capture the image and you see the result there will be a 1/3 stop or 2/3 difference in the final image output? I dont see there is a difference between the 2 images with the light on and with the light off, at the same EV value, isnt it the image should be 2/3 stop brighter at the same ev value????? if you turn on the light, as the lcd indicates? Where is the metering sensor located at in relation to the top LCD? and where is the cmos sensor located at, on 5d mark III?

It is not an issue at all in normal photography work situation, the object and the surrounding has to be dark for it to affect the ae. Even at f4, at 2 seconds iso 800 does not affect the ae metering when u turn on the lcd top light! with the lens cap off and view finder being covered. Is this really an issue??? at ISO 800, f4, at 2 seconds no change! I am surprised that people are really hyped abt this. the object you are metering and the surrounding has to be really dark for it to affect the ae metering!!!. My goodness and people are really getting so fussy abt this!! and who shoots with the lens cap ON?????????

People love to hate. I wouldn't expect any less from those that never handled one of these cameras (and I mean both the D800 and the 5Dmk3)

I draw my opinions on both handling and owning Nikons and Canons. It's my job to know the issues as I teach beginners and pros on both systems.

After three days of trying to make this fail in real world conditions, I could not. The only time I make it fail is when I throw on a lens cap on it. Even in .01EV @ISO 100 where I could barely read the LCD screen I could not make the meter fail.

The irony is people want to b**ch about Canon's problems, and typically, barely a peep on the Nikon issues (D800: CLS flash failures, LCD colour casts, AWB issues, CF card failures) things I've seen on my unit I've tested as well (who's denying now?). Are we surprised where the haters like to hang out?

They both have issues, it will be worked out while they work great in most conditions (I love both). This is so overblown. Put another bullet into the horse.

I have tested canon eos 5 d mark III, its not a problem that people should really worry so much, because with lens cap off the metering doesnt shift under a dim light condition, but it will shift around 2/3 of a stop under extremely dim condition, and we also encounter the same problems with at least 2 canon 5d mark II as well, and the question is why people start complaining now? we also try to conduct the same test on Nikon d300s because thats the only nikon camera we have available, Nikon didnt even bother to start metering with the lens cap on, and with its view finder being covered.

what you wrote falls in the same category as someone saying: BLUE is a better color then RED.

it´s just personal preference.. subjectiv.

so your whole commentar makes not much sense at all.

it´s just a nother nikon trolling about an "issue" that moves the exposure 2/3 stops. at -4 EV. no nikon or canon camera does a proper exposure at -4 EV anyway.

I've tried this on my 5DMk3 and in my opinion it's a small hiccup.

The way I tested it was:
1. turned the 5DMk3 on, set to M (ISO 12800, f4, forgot what was the shutter speed)
2. removed the eye-hood, then put black duct tape on viewfinder to prevent light going into sensor.
3. used 24-105mm lens with lens cap on.
4. turned off the lights in the room.
5. using iPhone4 LED, shone across 5DMk3 top-LCD.

Findings: the exposure reading altered by +1/3 to 2/3 ONLY when I have the LED 1-inch away from the LCD with it shining on the centre of it. When the LED was shining on other parts of the LCD, there was no impact to the EV.

I'm not too concerned about this light leak.

I'm more concerned about amp glow (pink-purplish) glow in the bottom right corner as I crank up the ISO up to 25,600 and beyond (51200, and 102400). Does anyone else notice something similar on their 5DMk3? It's easily seen in dark/pitch-black images.

Been reading most of the comments on this, and what most people are not grasping is the problem has to do with *ANY* light hitting the top surface of the LCD panel (like the sun for example), not just the backlight being engaged.

Basically the more external light hitting the top LCD, the more underexposed your image will be.

The following vid demonstrates this quite clearly: an exposure variation of 1EV is a very serious problem, no matter how you look at the issue!
http://www.youtube.com/watch?v=hh7OaF0Qh0Q

I'm a Canon user and would upgrade in an instant, but will first wait and see what Canon offers as a solution.

If no solution is forthcoming, then take the matter into your own hands, open up the camera (and void the warranty) and put some black duct tape underneath the LCD panel and you should be good to go :-)

he has the lens cap on... the camera does not see any light through the lens. so how many times you shoot at pitch black darkness or with a lens cap on?

i will explain it again, for nikon shooter.
if he had removed the lens cap, as a normal person would do for taking pictures (not sure about nikon user), you would see NO change in exposure.

at -4 EV you would see an change about 2/3 stops.... but then no nikon or canon does a proper exposure at -4 EV.

@Kinematic Digit, thanks for doing that test and going to the trouble of uploading a video.

You have proven two things:

1. There is definitely a light leak issue through the top LCD panel.

2. The light leak does not affect normal daylight exposure metering.

Now, if you're keen, I throw this challenge to you for another test involving night time exposure:

1. At night time, find a bright street lamp in your city and set up your camera directly under it.

2. Aim the camera at a very dim subject, but must be much darker than the street light you are under (lens cap off).

3. Meter the exposure as you did in your vid, using a piece of cardboard to block then unblock the street light from hitting the top LCD panel.

Myself, and most people here would be most curious to see the result of such a test :)

Let’s use a bit of commonsense here I’m tired of reading about “I never take photo with cap’s on” I know nobody here is an idiot to do that., they put lens cap here to test the light leak so that no (as in nothing) will affect the light sensor but the light come from the top LCD in other words to isolate the issue. Unless you can say that your light source that comes in from the lens is constant which I doubt, so to eliminate this you have to cover it. If we don’t cover the lens you will say that the meter was affected by uneven light source came from the lens – back to square on.

So if you want to defend canon on it, defend canon in a wisely manner because by mocking the test you look/sound s….d.

Sometimes to make thing good we have to eliminate the word so call D-E-N-I-A-L.

Peter I did just those test. I could not video it unfortunately as you can imagine that the lighting conditions would not video well and since my best video camera is the one I was using to test the issues:

I shot a long exposure of water fountain with street lamps behind me with results of no change. I did a light meter reading 3 EV @ ISO 100. Shading or using the illumination lamp made no difference in exposure times.

Tonight I did a long exposure shots and this surprised me a little. I measured the light again, this time only the ambiant light of nautical twilight. Measured at .01 EV @ ISO 100 (Could barely read LCD screen). This about extreme as one would get. I did both Illumination light, and light of my iPhone. No change in exposure readings.

Conclusion. Two nights testing, and I'm most certain that 99.5% of the time this will not be an issue. .5% is when someone has a police spot light on you while you're shooting into a dark crowd (maybe fails).

he (of course) compares the D800 to the 5D Mk3

------------------
The other problem I experienced relates to the camera simply locking up. The only way to fix it is to take the battery out. I don’t know if I have a bad copy or it’s a random problem, but I assume it’s something that can be fixed with a firmware update if it’s widespread.

Both my 5d Mk3's are locking up intermittently. So far I've lost two wedding ceremonies from these camera. I'm using genuine Sandisk extreme pro 32gb cards. I'm trying now to induce the problem at home to see if I can work out what is going on. So far it seems to me that the camera may be trying to right a file larger than fat32 will allow. Times the cameras have locked up have been around the moment the camera is about to split the file and start a new file to reach the 29 min mark. When the problem happens the footage starts to skip on the desplay for about 3 seconds then freezes. Only taking the battery out will unfreeze the camera. The footage of the previous 12 mins is lost completely. Does any one know of a forum dealing with this problem I can join? Canon really need to do something about this ASAP. The camera is useless for events until you can trust it will not loose your footage!

But why nobody had been bitching about it????? is this a marketing war between Nikon and Canon? canon mark III is already out in the market and ready stock in most stores and in most countries, and Nikon is still struggling with their d800 inventory??

all you need to rule the DxO Mark is a mobile phone sensor design at fullframe size.

quote from the DxO chief scientist:

Phone cameras necessarily have tiny image sensors that can't capture as much light as the bigger sensors on compact cameras or the even bigger sensors of full-frame SLR cameras. But for a given surface area of image sensor, mobile phone cameras actually do better.
----------------------------

looks like sony has done just that with the D800 sensor.

so the D800 is the better sports camera.... well at least if you believe the DXO scores.

and of course the D800 has better low light performance.

well if... and only if... you resize the images to 8MP

that is how DXO is testing the sensors... for 8MP print output.

the question is why buy a 22MP or 36MP camera then?

It' a minor hic-up that doesn't affect anything significant. I use it in long exposures and never have issues not using that illumination LCD. Also there's a simple work around it by locking the exposure with the * button as you look at the screen.

You can wait for a bit and let them work out the production issues. Other FF cameras are equally dealing with issues. There are delay's still going on both for delivery and for production issues as well.

you can shoot in the dark and the affect will be irrelevant.

but when it´s pitch black you will be off.... big deal as the automatic exposure in these cases is off anyway and you need to do manual finetuning anyway.

this whole thing is made up by nikon trolls and people who don´t have a clue what we are talking about.
they did not even notice that the lens cap is on in this infamous video that makes the round.

you can have bright sunlight but as long as the lens cap is on, a camera will not notice that light. because .. suprise... it goes not through the lens.
so yes... when no light (or -4 EV ambient light) comes through the lens then a small light leak will influence the AF sensor a bit.

for those who have the early runs of the 5DMkIII and still rely on AE metering sensor and the top lcd lit at the same time, a firmware update would be make sense as follows:

Assuming you can even view the top lcd (in cases where the camera is mounted too high above eye-level, LV can be used instead.
1) actuate the lcd light (deliberately or by accident):
2) 'holds' the exposure-iso-sensitivity values (but not locking them)
3) thus as soon as one deliberately makes any exposure-iso-sensitivity adjustment, they change as needed anytime, zero delays.
4) if the light goes out after the normal illumination, and one wants to review the values again, whether changed or not, repeat step 1).
5) one can 'tap' the lcd light button again and turn the deliberately light off.

If one does not make adjustments at all, one shouldn't have any problems

If one is looking over at the top lcd then light going into the OVF will also alter the AE reading given your eyes are not covering the OVF anyway...

Its amazing how many thousands of images have already been taken and posted from this camera (the one that's not selling and nobody wants). Some fantastic low light shots and an amazing view of a multiple lighting strike on the Bay Bridge. But to each his own. The people who made these shots could have stayed home, shining a flashlight at the top of the camera to see if the metering was affected.

True, but never the less, an error is an error no matter what you think, and it should be fixed if possible.

I think it is good that there are people shining a flashlight at the top of the camera, but I think that this happened first after when some other people, or the same ones, discovered that switching on the LCD light caused problems. Next step was of course to check if the problem was caused internally, or even external light can effect the metering. It's a logical step. If the flash light could not effect the metering it would be easy to have a workaround, i.e. keep the top LCD light off in case you worry. The "flash light test" may sound stupid, but it is not. I can easily come up with a situation where the photographer is sitting in the dark, taking images of a theatre scene or a concert and than some strobes start shining on him. If the metering is changed his images will be destroyed.

Sony and Nikon have a partnership. It's not like Nikon is just getting Sony's left over scraps. If you think Nikon had no say in the development of the D800 sensor for example you are living in a fantasy world. Besides Sony is making the best DSLR sensors in the world right now so I fail to see how Canon camera's can be better with inferior sensors.

Overall Nikon has been making the better cameras for awhile now thanks in large part to Sony's class leading sensors and canon's instant, pointless, neutering of features in their mid level DSLRs in a futile attempt to get people to spend twice as much on 1D series camera's.

The only good sensor's Sony ever made are the 16.2 MP APS-C & the 12.1 MP full frame sensor found in the D3S... beyond that most of their existing sensors are average at best...

Canon's 22.3 MP sensor in the 5D III is definitely a cut above most of Sony-Nikon's sensors... both in terms of noise and colour reproduction...

Exactly which Nikon camera is better than its Canon counterpart...? In the cropped sensor category the 7D was all round superior compared to the D300S... including in terms of pure image quality... ISO performance... video capability... autofocus aquisition...

2½ years ago the D3S was considered better than the 1D Mark IV in low light performance... but that was only visible beyond ISO 6400... From base to I600 the ID Mark IV outresolved the Nikon hands down...

I think all new cameras seem to suffer teething problems.

People here may remember the early 5D2's, where for some inexplicable reason too many of them were leaving the factory with dirt and dust inside the body. QC was not good. I had to return my first 5D2 for this reason.

Pentax had oil stains on their sensor. Nikon appear to have a few issues with D800's locking up.

Having experienced most camera brands over the past 20 years, my personal experience is that I have had more problems with Canon than Nikon with a similar number of cameras owned from each brand.

But I am just one person and therefore I am not an adequate sample !

I am sure it will get sorted out - but this is a physical problem, not something that can be fixed with a firmware upgrade ! Cameras will have to be returned, which is quite a headache.
