70d is producing shots with prominent white streaks! Cleaned everything. Sensor issue!? Thoughts?

LookingGlassGir — Fri, 12 Dec 2014 21:07:56 GMT

My 70d suddenly started taking shots with a PROMINENT white streak! The smaller the aperture the more prominent it is...this led me to believe it may be a dust issue ( although I have never seen dust accumulate this way) so I thoroughly cleaned everything. It didn't seem to help. Any thoughts? It seems as though it might be a sensor issue...which I would hate to replace!

Can you post an example?

Dust can usually be spotted by pointing the camera to something light with no contrast (a plain white wall... a plain blue sky, etc.) and taking a photo at very high f-stop (e.g. f/22 or higher) and again at your lowest f-stop. The dust will show much more prominently at high f-stop. If there's no difference between high & low f-stop, it's probably not dust.

You may also be experience some sort of flare... points of light will throw diffraction spikes at high f-stops and you can also pick up reflections or ghost (at any f-stop). Filters can be especially problematic for adding to flare or ghosting issues.

Here are two examples shot on diffrent days. Initially ( the birds) I just thought it was sunflare...and shrugged it off. The next day this appeared in every image I took! Slightly altered by setting and light, but it was alwayse present.

Thank You for your input!

Thank you!I tried this in my first round of trouble shooting, unfortunately it did not help.

This appears to be an internal reflection. It *might* be caused by the lens, but not necessarily.

Remote the lens and follow the instructions to put the camera into manual sensor-cleaning mode. This will cause the reflex mirror to swing up and the shutter will open.

Ordinarily you'd do this to clean the sensor... but this time you want to do it just to inspect the camera and make sure everything did, in fact, swing clear of the optical path between the lens and the sensor (e.g. make sure the mirror isn't just partially swinging up, etc.

If everything is swinging clear then it's possible this is in the lens (do you have more than one lens?)

You may wan to remove the lens and look through it with the lens pointed at a plain non-contrast subject... such as a plain white wall. You're looking for obstructions, etc.

You may also need to re-attach the lens to the camera, and do this again... but this time set a high f-stop (e.g. f/11, f/16, f/22) and use the camera's Depth of Field preview button. This would allow you to check to verify that all of the aperture blades are properly sliding in and out and you don't have a stuck blade on the aperture.

I do have several different lens options and the obstruction appears using all of them. Leading me to believe that the issue is with the camera body itself.

I went through the Manual sensor mode several times today both to clean and check for obstructions. The mirror seems to be functioning properly. The cleaning rendered me with a nice crisp shot.....of the streak!

I am stumped.

Looks like a shutter problem.

Yes it is a shutter problem. In fact it is a shutter blade is sticking.

If it's a sticking shutter blade, why doesn't the streak extend the entire length of the frame? Could it be a sticking mirror, possibly in the autofocus mechanism, instead?

Either way, of course, it presumably needs the attention of a professional repair shop.

It is sticking, not totally blocking.

I am having the same issue. Dropped 70D off this morining for estimate.

I believe the same issue reported here with a sample picture: http://community.usa.canon.com/t5/EOS/70D-light-leak-issue/m-p/133663#M12227

How much was the estimate? And how old is your 70d? It looks like there have been a rash of these issues, and I'm curious if the problem cameras are about the same age.

Have you found out the issue I too am having the same problem

It was a sticky shutter blade. Camera was still under warranty, so it was a free fix.

I had mine fixed at a local camera shop (Tempe Camera) for about $250 but that was over 2 years ago. They had it for about a week and replaced the shutter. I suspect the price probably has gone up. My camera is still going strong with the new shutter and I use it to shoot two or three games each week and a lot of fun stuff in between.

I see this is a common thing with Canons. Not happy at this moment that this is also happening with my 70D. I've never had an issue with Canons before this.

I think its prpbably a failing shutter.
