In reply to baobob, 6 months ago

Yes I see the light, I'm sorry to say but only when I have the lens cap on. When the lens cap is off no purple light, I even took a 30 sec exp  with the door open no purple light. I don't know more testing needs to be done.

Stop bombarding me with your facts and sciences!

This does not effect my style of shooting, but was thinking about it anyways. Would a simple fix involve a plastic plug or cap for each of the affected openings? Something like this must exist already.

Yes there are certainly dust plugs for all type of connectors including hemi and phone jack.

After all, if you shine a torch into the ports on other cameras they may have the same problem. In which case, this is not really a very big deal since without the torch noone would notice.

The issue was first noticed in real world use, then demonstrated by shining a light into the camera.

Real Example

Why do some people repeatedly insist that such real issues don't exist? The sharing of these issues and how to deal with them is one of the great benefits of participating in a gear forum. I hate wading through all the apologists posts to find useful information. If you can't stand to read about the weaknesses of a camera, then don't open threads that discuss those weaknesses. If it is not an issue for you, then move along.

Since this is not your forum I don't really think you are in a position to dictate what I can and cannot read or say, or complain when other people don't share your reaction. That's what happens in forums.

Yes, you are free to add as much noise to the forum as you wish. I appreciate other forum members whose contributions are more level-headed. I hate all the troll vs. fanboy banter; it just mucks up the place.

It is NOT a big deal even if you want to make it one, especially as most people can't even seem to replicate it.

I don't really see how anyone is making a "big deal" out of the issue. There is no need to exaggerate the issue and there is no need to blindly dismiss it. A simple exchange of information would be great.

I did not dismiss it. I wondered if a similar test of other cameras would highlight a similar issue. At least there is a workaround (use the RC app or the self timer or black tape). If the problem had come to light with the XE2 as well, then it would be a generic problem. Seems it is not.

Many problems in the build stage require a factory rework (Nikon D600, Canon 1D2) which is a lot more serious. No workaround unless you clean the sensor every week and risk voiding the warranty.

But some of the chicken littles have already sent their cameras back to Amazon and there is already another thread on this. Personally I would just carry on using the camera. If there is a fix I have a year to decide if I want to implement it.

In reply to D200_4me, 6 months ago

As far as I can tell my light leak is only through the mic port. I thought at one stage it came through the HDMI port as well but when I tested it again the light leak stopped when I put a pen in front of the mic port only.

I did long exposure night shots last night with a wired remote. No light leak effects at all. I think we can relax about this unless someone can see a situation where it would be a problem - I can't at this stage.

a funny think happened on the way to the forum
In reply to adfhg, 6 months ago

I checked my camera this morning and low and behold. the leak is there. frustrating but not a deal breaker. I would prefer perfect but I can manage.

This afternoon. I looked again out of curiosity and reading more of this forum. Gone? WHAT? yes gone.

Hmmm..

I played around with settings. With lens 23mm on A I see leak easily. With lens off A very difficult to repeat leak at all, but I can manage to get it to leak slightly in bottom right corner of frame at all F-stops --but takes a lot of changing angle of torch - etc.  When on Auto - clear as day.  The purple banding when aperture is off A is difficult to reproduce.

Even stranger is that it is definitely the ports.  I can close door or cover ports no issues at all.  Shine all around edge of lens if in auto or manual no issue.  but with lens on A and light shining in ports it's very apparent.  WHen in manual hard to reproduce.

Curious as to if others see it more so with aperture in Auto.  Odd that would be the case - but it is on my camera and lens combo.

some more testing - (this is absurd way to spend my time - I know.) and It seems to me to increase with lower shutter speeds as well. IF that helps anyone at all.  But yeah seems to have to increase when lens is on A or length of exposure is long. Makes some sense I suppose you are telling camera to increase sensitivity to light and it sees a stronger leak -- prior to shutter release --

Im don't with this playing around for now.  Just wanted to pass along what I see with my messing around.

I've used the 5Dm2 and 5Dm3 for video production and still consider them subpar in both terms of video quality (without Magic Lantern) and usability for actual video shooting. Yes, it is a tired debate but these bodies are optimised for still photography and it results in a horde of practical issues with video.

Four years ago the mark II caused a small revolution in digital video, but imho the honeymoon period with DSLR cinematography is nearing the end and indie shooters are migrating towards purpose-built budget(ish) cameras like the C100-300 and Black Magic products. Panasonic has chosen to emphasize video features in their m4/3 cameras with good results, but at the expense of still photography, where their IQ is lagging behind competition.

Raw video provided by the ML hack on 5Dm3 has secured the DSLR a spot in production situations where a RED is too big or costly, but the XT-1 is a far cry from that. Even the ancient mark II is miles ahead of the X-T1 in what comes to video features, and even if there are users who want video, X-T1 does not deliver on that front at all, and I'd prefer Fuji leaving them out from future models.

I think the real winner for 5d was the fact that you could snap a high quality photo lens and have a camera system that would otherwise cost many tens of thousands at that time.

But I agree the dslr video period is almost over, and I see using 5d's only in a very budget restrained productions that can't rent red or such. Sort of out of a necessity, while years back it was the big thing.

So I also agree that forcing so called professional video features to photo cameras today is just making it look good on paper. Most of those consumer cameras wouldn't be the choice of professional videographer regardless if it has mic input or not, but all reviewers always seems to put lack of mic input as a big negative in their reviews. Sort of like a pretend play so we can wire our pretend Lavs to our pretend pro video equipment to make a pretend YouTube viral video.

ISO matters a little and lens cap ON matters a lot...

You caught on to something here.  After seeing the example someone posted earlier with sunlight shining on the port from the window causing the flaring, I thought I'd try that when I got home.  I went outside on this very bright sunny day and opened the rubber flap.  I pointed the open ports directly at the sun and moved it around.  Nothing.  No flare at all.

After seeing your post now, I tried the LED flashlight test again (which of course is a little unrealistic condition) here inside my house.  With the lens cap OFF and the camera manually set to ISO 200, I could just BARELY see the flare and I had to position the light JUST right to even notice it.  However, if I set the camera to ISO 6400, I could see the flare a little better, but still not too much, which the lens cap is OFF.  Put the lens cap ON and the flare is very easy to produce and it flares very large and all the way across the screen.

Bottom line for me?  I don't really do much shooting with the lens capON ...and...I don't do any high ISO long exposure shooting at all (high ISO seems to make it a little worse, but not much at all, with the lens cap OFF)...so I hereby declare this a false alarm and a non-issue for me (me personally).   You all may come to a different conclusion, but I'm officially ignoring this because from my own testing, I think it be very unlikely that anyone using the X-T1 I have in front of me to produce this flare in a real shooting situation.

it is like the orbs on x10
In reply to adfhg, 6 months ago

I have x10 and it have the famous orbs. It doesn't bother me a single bit as I don't use it to take night pictures of skyline. But the fact is if it bothered me I could send it to Fuji and they will replace it. I didn't it is not worth for me to pay shipping to change something I don't really care about.

Same with this. It will not affect me a bit because till now I produced exactly zero long exposure photos with any cameras. But I think people should be able to send the camera to service if it really bothers them and have a black tape glued on the back of the ports. As with the x10 I would personally not feel it is worth sending especially if in the unlikely scenario I need to shoot long exposure with door open I can simply put a tape over the ports. But sure it needs to be addressed by Fuji.

Welp, I did some long exposure tests and can definitely see light if it's shining into the ports. It is pretty easy to block. In fact, my cable release seems to block it almost entirely for the mic port anyway.

But, it's still completely unacceptable. I suspect there will be a service advisory. I intend to contact Fuji USA repair and report the issue and see if they can fix it immediately on a case by case basis. If not, I will consider returning the camera until the issue is resolved or at least acknowledged by Fuji. I do enjoy long exposures from time to time (why else own a Lee Big Stopper?) and while most images will not be affected by this, it's a painful thing to have an expensive device that has a flaw that it should simply not have. It would be like buying a sports car that was designed to go 150mph but yours couldn't. It would explode at 100. You almost never drive over 85 so you don't really care. But, you'll also know you can never take it to a track and open it up.

That's just wrong.

And so it is a real problem that is mitigable, but, not irrelevant.

For those keeping track, I am aware of a light leak flaw on the Sony A7R (and possibly A7) as well as Canon 5D Mark III.

Sony as announced a service advisory, and Canon fixed their bodies in a similar manner.

In the case of Canon, the light leak came in through the top LCD panel and impacted exposure metering even when not doing long exposures so it was actually a more serious flaw. The amusing part? They repaired it with electrical tape inside the body. Perfectly reasonable, but, amusingly simple to me.

It does appear that others have tested and found their X-T1 unaffected by this problem. That's great news. What it means is most likely there is simply a part missing from the affected cameras and it will be easy to repair.

I should mention that I got my X-T1 via Amazon in their initial shipment.

I don't think there are unaffected xt1, just people not testing it the same way. What you see on LCD monitor is the amplified image that depends on the aperture and ISO set and other settings. If they actually go and shoot long exposure and shine light to their ports they will have the leak on the final image for sure. Fuji just need to put a tape on the back of the ports. Simple but the cameras they are sold now had been assembled some time ago so it will take the time to get to production.

Hi,

with all respect - this is really a stupid and escapist test.

If you check all cameras on the market in this manner, a lot of them will show this kind of "issue".

The next one will open the card slot, doing the same "test".

Even in bright sunlight, and open flap (because using a remote) this area will be in shadowed, and the main source will be plugged.

I dare to say, that in 99.999999999% of all situations this will NOT be an issue. So far ahead of the most demanding six-sigma demands.

Tell him about that : http://www.dpreview.com/forums/post/53213359

From an engineers point of view I can only shake my head and pity all camera manufactures in todays time. People are obviously buying cameras only to search for the tiniest flaw, even if it doesn't matter for any practical application - it's kind of a hobby. Technic nerds, but for sure no photographers with some sense for reality.

To make it clear, I am not defending Fuji here, I am openly blaming the narrow-mindedness of so many users today. Hang me for it, but that's my opinion.

Regards,

Daniel

From an engeneers point of view I can only say, "Sh..t happens. - We got to fix it  a.s.a.p.".

It is Fujifilms top notch camera modell claiming to be dust and moisture sealed. In the meantime several users had dust spots on the sensor which can not be removed. There might be other issues which are not found out yet. At least the sensor assembly should be an all around sealed unit ! But light entrance and dust under the sensor´s protective glas does not speak for an engeneering effort which can give the customers much confidence to the over all quality of the product.

Have fun ...

Rudi.

I haven't heard anyone say the Fuji X-cams have professional video features forced into them.  I think this is the wrong forum for that complaint.  Even Fuji has said they've put no priority into video as the X-cams are still cameras.  I would think most still camera video-haters would be happy with Fuji's "keep it minimal" video approach.

I got mine as just a body through Amazon and it most definitely does have the problem, so body only shipments from Amazon are no guarantee of not having the problem.

That said, I don't think it will effect anything I do personally, so I'm not going to worry about it.  I understand that others may have real issues, but I don't - happily.  Also, it looks like there should be an easy fix - little caps for unused ports or whatever.  Or that always dependable remedy for most mechanical problems - tape.

The light shining into the jacks was to demonstrate the effect that is clearly seen while using a cable release for long exposures.

Light leak example

I think the issue now is whether or not it is a QC or design issue. I'm guessing the best current workaround is a plug in the offending jack or some black tape.
