EOS 70D Light Bleed Artifact

A band of light is showing up on 90% of pictures. Tried changing lenses and it made no difference. Does anyone know what could be causing this?Light Artifact Sample 1Light Artifact Sample 2

Greetings,

I believe a similar issue was recently diagnosed in another thread. This appears to be a failing shutter.

Thanks for the reply! Yes, I did a more thorough search and the shutter is the issue. Looks like the repair cost will be around $300? There is a Canon Service Center in Burbank which isn’t too far from me so will drop it off when they open on Monday. The camera body is probably not worth much more than $300 (its 10 years old +). I’m wondering if I should put the $$ towards a new camera? Would appreciate any recommendations. Thanks!

Its good you tested with another lens. To be sure, you can reset the camera's settings and test with a freshly formatted SD card. If its still present, you'll have your answer.

At that point, you need to decide if its worth repairing. Best guess is $430 ~ $550 depending on the parts needed. A new or refurb mirrorless body is probably more affordable than you might think and if you buy an EF to RF adapter, you can probably continue to use your existing glass.

I need it mostly for headshots for actors (for which I use the EF 85mm lens). I'm seeing used 70'D body's for as low as $200 or I could upgrade to a 90'D refurb for around $800 for the body only. I shot with Nikon DSLR's for years and never had this issue and I'm concerned that if I go for a used/refurb this will happen again if I go with another Cannon DSLR. Although I had the 70'd for a long time, it really hasn't been used that much. If I go for a refurbed mirrorless is there a model you would recommend? I guess if I purchase the adapter I can still use the EF85. Thanks so much!

Greetings,

If spending the least amount of money is your goal, and you can get a shutter replaced for $300, that's attractive. If the 70D has been good to you and you are happy with its performance, repair at that price could work.

If however, you've reached a point where the camera isn't meeting your needs or you want more, then I'd put the repair money towards a new body. If you decide to go this route, a mirrorless body is the way to go. The R8, R10 or R7 would be a significant upgrade from the 70D. Note, you'll need a EF to RF adapter which is $100.

The EF 85 would work nicely on the full frame R8. I own this lens and its razor sharp as you know. On the R10 or R7, you'll get a FOV equivalent of 136mm, similar to how the FOV looked on your 70D. Canon also makes a RF135 f1.8 which is a portrait photographer's dream on a full frame sensor. It would not be my first choice for portraits on a APS-C body, but its a spectacular piece of glass and something to keep in mind for the future.

A refurbished R10 is $699, then grab the adapter $100. Its will seriously run circles around any rebel DSLR without breaking a sweat. It will also bring you up to date and open a whole new photography experience for you.

Thank you for the super helpful reply. The EOS R10 feels like the way to go. 🙏

I believe you'll be happy with it. The R10 has the advanced controls some of the lower end models skip putting it in a unique spot. It also comes with Canon's latest AF software, (animal, eye, vehicle and face tracking). 4k video and a bunch of connectivity options. You can visit Best Buy to hold one. Moving from the 70D to it will be very natural. 1-3 days to acclimate and you're going to wonder why you didn't do it sooner.

Post some shots for us after you get it 🙂

Dropped off the camera for repair at Canon in Burbank and the quote to fix the shutter is $349. I can find a used 70'D body for quite a bit less (however shutter count would be unknown). I would like to get in a little closer when shooting headshots as with the 70D with the EF 85 I need to be about 10ft+ back to get a headshot (that isn't just a head 😆) with some amount of bokeh and I'm considering stepping up to a full frame and looking for a used/refurb R8. There is an R7 on Facebook Marketplace right now local to me going for $1K which is tempting (although not full frame). There are also plenty of R6's used going for around $550 (although the R6 does not feature the higher resolution sensor, faster continuous shooting speed, longer battery life or the improved circuit design for better heat management for the R7, R8 & R10). Would love to eventually get my hands on the RF135 f1.8 but that's currently beyond my reach financially. My use case at this time is just for portraits/headshots.

In your boat today, I would buy the refurb 90D without second thought. Of course everything is going mirrorless and I understand that but the 90D is an extraordinary camera It is the best cropper ever made. I would couple it with the Sigma 18-35mm f/1.8 DC HSM Art Lens. There is most likely not any other camera/lens combo that can top this combo for IQ. That's what I would do well before spending $350 bucks on a T7i.

Much appreciated thanks! I’m still probably looking at closer to $600 for a 90D body and unless I get a “refurbished” one with some kind of warranty, I’ll be taking a risk in terms of reliability. My primary incentive for repairing the 7OD is that I will at least have a rebuilt shutter that will hopefully last me 100K shots (according to the tech at Cannon it only had 40K shots so it really should not have failed this early). I also went to Samy’s Camera yesterday and tried out the R10 along with an R. The rep was of the opinion that the issue with my 70D was more likely related to the censor. After my experience, I’m nervous about purchasing a used DSLR. I also philosophically don’t like the idea of literally throwing the camera away. I have been able to get some good shots out of the 70D over the years and the lens along with good lighting (and mostly luck in my case 😝), is what really makes the difference.

You know anything is a possibility but the chances of it being the shutter is far greater than it being the sensor. Plus it doesn't look like a sensor failure. It is a 10 year old camera and everything else about it is 10 years old even if you get a new shutter. Canon refurbs carry a full one year warranty.

" I will at least have a rebuilt shutter that will hopefully last me 100K shots (according to the tech at Cannon ..."

Actually he isn't absolutely correct. The 100K figure is an average. You know how they arrive at an average? Some will fail after 100 shots and some will fail after 200K clicks. But the average shutter will average 100K, if it was a guarantee and it is not by any means, that would be a whole different ballgame.

I can only advise on what I would do and that would be to the buy a new camera. Right now the 90D refurb looks like the winner. It is the best Canon cropper or perhaps even the best cropper by anyone ever. IMHO, as always.

Thanks so much EB. You make a compelling case for the 90D which are going between $850 and $1K for body only depending on the condition/shutter count. If I can find one for $750 I'll go for it. It would be cool to go mirrorless, but I didn't care for the feel of the R10 as recommended by Rick (or the RP which I also tried) with the EF adapter ring and my EF lenses (although no doubt I would get used to it). Have done a bunch of research over the last few days to get up to speed on the Canon mirrorless line so thanks to this and the helpful advice on this forum I'm better informed now. Thanks again!

Since you have a 70D the 90D will feel right at home in your hands. I know this is a lot more money but I got to use a 90D with a Sigma 18-35mm f/1.8 DC HSM Art Lens on it for a little while form a friend. It was/is the best combo for IQ I think I have ever used. Certainly not going to be surpassed by many if any. It is one combo I wish now that I had bought for myself. Only my age and reduced requirements have caused me to not buy it.

Most of the time I would recommend folks buy mirrorless but certain circumstances are different and in your case the 90D seems a perfect fit. If you decided to go with one of the mirrorless models I would still be happy for you.

Addendum:

If you want even more IQ if that wasn't enough from the above combo, get the 90D with Sigma 35mm f/1.4 DG HSM Art Lens. IMHO, the Sigma 35mm f/1.4 DG HSM Art Lens is the sharpest lens made. On the 90D it is nothing short of fantastic. (As it is I am sure on any top level camera body.)
