LensRental's Roger Cicala examines Canon EOS 5D Mark III light leak 'cover-up'

By dpreview staff on May 2, 2012 at 18:29 GMT

The ever-inquisitive Roger Cicala at LensRentals has dismantled a light-leak-fixed Canon EOS 5D Mark III and compared it to an unmodified version. The solution, as proposed by every tool-shed tinkerer, appears to be a piece of black electrical tape, which Cicala says successfully stops stray light reaching the camera's metering sensor. When asked if he'd send his own Mark III back to be modified, Cicala points out that he doesn't 'do long exposure night photography with autometering.' But, in the unlikely event that you do, you can rest assured that Canon can fix your camera for you.

The 'light-leak' issue for the 5D III involved light from the camera's top-plate LCD illuminator reaching the metering sensor and skewing the results. The metering errors caused by this stray light only came when trying to photograph extremely low-light scenes (a situation in which it's unusual to use the camera's metering).

Just picked up my 5DMk3, I did wait for the latest batch with *****3***** serial # as do quite a bit of low light work. Happy with image quality, speed, feel of body and love features now brought to the for such as mirror lock for long exposures to reduce blur from mirror bounce. I have enough pixels and features to make me a very happy photographer. Let's all get out there and put some great images on this site to inspire others, either from a Nikon or a Canon.

Hi,
have you tested the EOS 5D Mark III night time with just street light without flash with the following settings?
ISO 104 000
shutter speed 1/500 or 1/800
85 mm lens
F 1.8 or lower

The answer is simple. One you have provided yourself. Second is : because you can... or should be able to as per manual. People do strange things with cameras, pros too... that doesn't mean they are idiots. They do use it within a provided spectrum of options, don't they?!!! So who are you to call these ppl idiots? They use it within design parameters and both a camera and manuf. should deliver on all levels. An item like this is deemed 1st grade, not some DIY project. For Canon to overlook a simple leak in this one and G1X is unforgivable. They should know better. This is camera builders 101. If cameras could kill like cars we could already be missing few guys... Recall is a recall... This is Canon's fault, period. This is not a $5 ToysRus gadget. Some ppl put serious coin to upgrade to their dream camera so have some respect and don't be a jerk. Just because you think you know better doesn't give you the right to call others, dismayed by the whole thing, idiots (!).

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!!!

Many of the comments in this discussion simply demonstrate a not-so-surprising fact that very few people who are interested in Photography have very little (practically none at all) knowledge or idea about industrial manufacturing processes and techniques. Use of specialty tapes for manufacturing phones, cameras, tablets, laptops is a well-established technology. tapes play a very important role in industrial manufacturing. Using a tape is not a "cheap fix".

For reference - do a google search on "Speciality Tapes".

i'm sure the tape will survive intact where it is even if you drop the camera from the top of the empire state building. would that be durable enough? of course, its job is to shield the sensor box from light leaks so how exactly do you want to measure the tape's durability?

My D7000 had an accident once, guess what holds that together these days? Same goes for the loose battery door on my F5. And my D300 had a fair bit of black tape covering areas where I'd damaged a part that was previously weatherproof.

As my colleague stood behind me just said, would you rather it's fixed with electrical tape, or not fixed at all?

Well, reading this response I'd rather you be more careful or have better luck in the future. 4 bodies here, and none of them need to be held together by tape.

That said, I agree tape isn't a "cheap fix." You'd be surprised how much tape is used in many applications where it is the best way to hold things or shield (as in this case) in a way that doesn't add excessive weight.

Oh, one other thing... take a good look at the two camera tops illustrating the original R. Cicala article. Besides the black tape, there are at least half a dozen other design changes between the two. Different parts, assemblies moved around, etc. Why is this and is one improved? Different plants in different countries? Changes due to recognized problems? Cheaper or more efficient methods of manufacture? Parts or supplier shortages? I'd be more concerned about all those changes in the design between the two models than about a bit of black tape. It does leave one to wonder about who designs these cameras, and how well they are tested BEFORE they go to manufacturing. On the other hand, have three Canon Powershot S3IS "superzoom" PnS at home which are our "everyday" carry around cameras (bought an extra "in case" never used it), and one has over 100,000 shutter actuations on it, never failed me yet. Never took it apart, and have no idea what's in it, but it works, tape or not.

In the second picture the body is angled much more to the left than in the first picture. Also the light falls differently on the two shots.This make it seem that some parts have moved (especially the lower middle PCB) but they are still in the same place. It also makes the black part next to the middle PCH hidden in the second picture. Also the the lighting make some parts seem a different color between the two pictures. I have a hard time finding any differences except the tape.

Also try follow this link (also from LensRentals) and see their Canon 5Diii strip tease:

Note all the black tape. Which didn't bother anyone (has been posted a month now). The link proves that tape is not an uncommon material in electronics design.

This is my first posting to dpreview, although I have read quite a few comments over the years. Some photographers seem to be way to concerned about fighting over brands than using their cameras creatively or for work (or both). While I agree that manufacturers should try to get their designs correct without having to recall their products, we demand complex cameras at lower pricing, and new models continually. As a general comment about ALL the manufacturers (and I own Nikon, Pentax and Canon DSLRs, and have owned Hasselblad, Konika, Nikon, Rollei, and Minolta SLRs/film cameras) I wish they all would produce products designed more durably, offer firmware upgrades to keep them as current, and stop making new models and incompatible lens mounts continually. No wonder they introduce bugs! BTW, all cameras and lenses use tape in their construction in the last dozen years. My Nikon D zoom lenses are held together with factory supplied standard cellophane (Scotch) tape.

Guys, dont be upset by this tape issue...its an expensive product, i know, and by right shld have an "expensive" solution to it too.

But what to do?? Sales is of utmost importance to any company..time is money for them...the longer you delay resolving a problem, the more loss you suffer.

If you have the money for the 5Dmkiii, i suggest you go buy n enjoy it...and remember to share it wth ur close family members, pics n usage as well (that's the best kind of sharing, imho) Just look at people like Brian Carnathan and Bob Atkins..love how they get their family so involved with their hobby..so much joy and love. Just love it! ^__^

I wont have the cash to bring this 'guy' home....but certainly love the good pictures others produce with it...and will keep enjoying the pics it can churn out.

That's all.

I admire Canon very much and think they are the kind of brand that takes risks, differently from Nikon, which I also admire almost the same level (not that often), but that plays much more in the conservative or tried-and-tested (by others) side. But, I have to tell you, a light-leak problem coming from Canon and in a camera like this one did impress me. I've never imagined such thing could happen. It looks like amateurs, beginners fail; something easily forgiven in a handmade camera.

Actually tape is used in many places in the D700, mostly to secure wiring to keep it flat and tight to an assembly. I see nothing wrong with the "fix" and I am somewhat a Nikon partisan.
The 5DIII has some nice features, and it is an evolutionary step upgrade for the 5DII which is very popular as the first cheap FF camera to gather a following. My only problem with it some of the problems of banding and artifacts are retained from the otherwise very good 5DII. That is the main issue which keeps me in Nikon's higher prices, until now. The D800 is an absolute bargain and I hope to have mine on May 14. My new 24-70 arrived today. No tape.....;>) actually there was a light leak issue with that highly thought of model, and it was permanently fixed with ......tape.

Stop this perpetual masterbation - they are just CAMERA manufacturers, and we can all buy or not buy their products as we choose. And if I want an Olympus SLR, a Nikon scuba camera, and a Canon compact, that's my prerogative. Anyone who dares say different, go buy some more Kleenex.

Does anyone take photographs with their cameras? We use the MK III’s for our work including weddings, portraits and engagements. Like all our Canon gear they work and they work tough. We’re not gentle. They are tools of the trade. Is the 5 D MK III worth the investment? Yes. It is simply better in every aspect over the MK II. And the MK II is no slouch to a hard day’s work. Do we care how the guts inside are done? Nope. If it didn’t work then Canon would fix it. But they do work and provide a positive return on investment over and over.

I see many people complaining about "the malfunctioning 3000+ USD Canon camera". Wooooow... And about the solution adopted. So there are two things here, it seems: the "wrong" design of the camera and the value of the item. Just to give you an example: something went very wrong with Apollo 13, just one item part of a MULTI-BILLION USD program. The astronauts survived because they used tape. In order to make the link between cube-shaped and cylindrical air canisters. So, you see, it's all about tape. Regarding both crew survival and your pictures survival. No worries, Canon surely knows by now that there is a design (or the robot just forgot to insert the tape) flaw and most probably they will try to calculate the cost of a "proper" solution. If the cost will not be justified, you will continue to see tape inside. But fortunately no "light leak". P. S.: without recognizing the flaw, Canon would have been in serious trouble - from me at least (remember the 1D III AF "story"). Cheers! :)

Wow, guess duct tape really DOES fix everything. Sad really, that such an expensive piece of camera gear has to endure being taped up like that just to make it near perfect. This is definitely not a case of "you get what you pay for", but more a case of "if it ain't really, truly, honestly broke, fix it for as little as possible, and hope no one notices".

A product's defect is a defect, whether it affects the vast majority of that product's users or not. Tape is the poor man's solution, and the new 5DIII is NOT a poor man's (or a poor manufacture's) camera.

I sincerely hope the 5DIII doesn't get too hot inside during extensive use, or that tape is going to be losing its adhesive all over the insides of the camera.

a minor fix for a minor function used only by folks still using AE metering sensors.
it's no surprise that beta testing would never look at this; except next time round, assume AE metering sensors still included in the next update (most likely).

one improvement that would eliminate future issues would be to allow the top lcd which is currently a fixed one facing only up be capable of tilting up and face back toward the viewer and even a bit downwards. At least then, one can read the lcd (even better a thinner stronger more robust OLED) when standing behind the camera mount on a trip set well above eye level. An OLED wouldn't need to be side-lit at all. And if it were at least a lit tilting top lcd, past light leaks on an AE metering sensor would never be possible.

I never use AE metering sensors anyway, under any lighting conditions.

I prefer using realtime fulltime full FOV image area live exposure evaluation instead. It's much more accurate than any AE meter sensor by any Mfr

Plenty of cameras have had problems when first released that were hastily (or not so hastily, Fuji) rectified. Heck, half the time when there's a new major release we play "guess what the fault will be".

Are these the problems you had personally experienced with or are they things that you have heard? I have bought over dozen cameras over the last 30 years and nothing fell out at first uses. I would not call firmware updates on modern digital cameras defective...

My user name should be a hint - I (well, we - a bunch of us use this login) work in a large camera shop. They're all problems with cameras that have been present when they went to market, and the various manufacturers have either recalled stock from us, or at the very least made a public announcement.

Lessons are learned everyday, some the hard way.

Not only for Canon, but to all high end DSLR makers like Nikon and the rest.

They will take attention to this phenomenon.

Be sure when making your so called magnesium alloy chassis and your poly plastic skin covering, remember to ISOLATE the penta prism from the rest of the innards.

This not only protects it from light but also from the pesky dust bunnies that come from everywhere within the cavity.

In the case of the 5DMk3, the light meter sits on top of the penta prism, almost at the bottom of the hot shoe for the external flash, a fair distance from the top LCD. It is a challenge to bend the light like Beckham from the LCD to the top of the camera hot shoe area.

I wouldn't ever use sticky tape in the internals of such an upmarket camera. I would either live with the "flaw" (if I hadn't known) or I wouldn't buy it in the first place (if I had known).

My opinion is that there is a minor problem with a new model. A fix has been found for anyone that wants to fix the problem. Anyone that has read the whole article referred to and others by LensRentals showing disassembled equipment would realise that the 'tape' being used is a normal component of any or even all electronic devices. So to bang on about 'sticky tape' is just ignorant.
One can question the quality control processes for sure. One would not expect a camera from any company, to be released with a problem however the problem has been fixed.
I own a Canon but my responses would be the same if this problem was with a camera from any manufacturer. I own a Canon because many years ago I started with a 1000FN and I could not afford to change horses now.
I spend a lot of time reading this forum but rarely post because so many of the querys end up with the same X is best Y is crap arguements that are so pointless. The comments on this news item just irritated me more than usual.

That solution what is showing has glue at the site where 1 chip and some connectors are mounted. This glue can have effect on the chip (legs), connectors, components like resistors and capacitors in long term. As former camera technician from another brand they often use hard plastic and fix it on spots the are not related to to electronic circuit.

A good solution is a simple solution. Why bother with something else if simple tape takes care of the problem. Plus it's inside the camera, means it's not changing aesthetic of 5D3 at all.

My only problem with this is the certain knowledge that most generic sticky tapes have a glue which eventually fails, either through drying out, moisture absorption or melting in the heat of sunlight. Furthermore, in the latter two cases, adhesive may seep its way into places where it is not entirely welcome - such as around the pentaprism.

Fine as a bodge, but a simple custom-moulded part would be much preferable here. Canon have cut a corner too far.

Perhaps a little too much testosterone around this forum for the general good ... if you want to think me and idiot, fine, that's your loss. And where, exactly, is the rest of this tape? Evidence, rather than loudmouth hot air might be a positive contribution. And of course, there are some great adhesive tapes ... but do we know this is one of them? With several camera bodies and lenses that I own from assorted "top shelf" manufacturers, there are all to many body coverings and suchlike that have worked loose over as little as 5 years - but which at least are all on the OUTSIDE, and so can be stuck back down. I wonder why these didn't use those "amazing" adhesives?

FACT: bodging with (even hi-tech) Gaffa is still bodging.

Very true what u said...believe it or not, i just got my 550D rubber grip replaced by my local Canon service centre as it came out (wth a year plus of warranty left, so paid nothing for it all..hehe), along with replacing the silver tape on my 18-135mm lens which also detached itself, and glueing back a peeling light absorbing rubber lining at the rear end of my 55-250mm...yes, three STICKY TAPE related problem in one visit...tho they did a quick (only 2 days) and good job (gave me a new grip and silver tape) without any fee and with absolute politeness.

Well, the people in the country i live in usually are mild mannered..so, it will be a different story perhaps for an American Canon service centre, no offense ya, where i read lots of rudeness and incompetence going on for non-CPS customers, that is.
Yep, a bodge is still a bodge, like it or not..either people will overlook it, or stand up against it. For me personally, i'm learning hard to live in the "overlooking" camp ^

I dont blame those people for "fussing" over this tape thing...

Though the tape solution is very cheap & practical...esp. for Canon themselves...it is done in SUCH a cheapskate, unprofessional-looking, crude, and almost rude & offensive manner for those buyers, who paid a high premium price for an equally premium product like the 5Dmkiii...at least this is the kind of "feeling" that i got, when looking at Roger's uploaded pictures.

Did he tampered with the tape itself? Did he peeled it off to have a look and put it back? i dunno...

Canon should AT LEAST get some of their brainy engineers to come up with a simple, cheap molded plastic made of ABS or sth else to cover it up. They could easily appoint any company anywhere in China, which specializes in plastic manufacturing. After all, things can be done very cheaply over there..well, like as if we dun know tat ^__^

But of course that will consume lots of time...thus loss ..not in production, but lots of loss in sales around the world

Of course i know my friend...that's why i said its "practical". Did you not read that part for yourself? Hmm? ^_^

Yes, i know its used elsewhere..go read Roger's other link on 5D mk iii Strip Tease..cool and daring attempt by him and his mate..tho i know there are many others who took apart DSLR for modding.

No, i did not neglect that remark deliberately..."smart & intelligent" readers like you should be able to read and comprehend that part for themselves. Furthermore, Roger said this too, "I HAVEN'T SEEN this on other cameras.." in the Strip Tease article regarding the extensive usage of tape in 5Diii.

Yes, he did "his best" too to say lots of good stuff about the tape later on..for surely he doenst wanna do a disservice to a giant like Canon, rite? ^o^ ...go read the whole article for yourself. ^_^

On another note, is there a serious flaw somewhere in the design of the mkiii circuitry (or many flaws) which may cause the internal components to interact disruptively with each other, and that's why they are practically slapping on layers of those tapes everywhere, just to prevent that? I dunno...after all, Roger said Canon almost entirely redesigned the innards of the 5D to the point it shld be renamed 6D, lol...but he did say "it’s one of those where I want to compliment the engineers. This camera is beautiful inside, logically laid out and well built" just to be fair....did canon reveal the reasons behind it? Any who knows?

I'll try googgling first...hehe ^_^

Brilliant, gonna promote you to CEO! Look, i think the disappointment that i find in this whole debacle, is that they were on top of the industry, we got used to that, then they brought out two horrific cameras that didn't work properly, the 1D3 and 1Dsmk3, who refunded all the photographers who shot studio work with the 1Dsmk3 when oil spilt onto the sensor and re-shoots were done? Not Canon. Its become a race, there should be a moderator a standard, not people who are satisfied with subpar performance. Again problems found on AV in the dark,is not such a big deal, but when the next problem comes around, will black tape fix it.......?
