Hey there. I went about with my Canon 70D. Started noticing a shadow appearing on the left corner of the photos when viewing. The higher the exposure the larger the shadow. Any ideas? Maybe just needs to be cleaned?

With all the lenses?

Yes I have a Tamron 16- 300 on it now but I tried my 50 and I got the same result.

Does it go the whole left side, or just the corner? When my shutter was dying, it was a shadow on one side of the image. (can't remember left or right)

Hmmm... Now that I think of it, it could have been top or bottom. Ignore me.

It's just on the one side but the higher the exposure it takes up more of the picture.

Sounds like a shutter-failure-warning symptom to me :-(

The shutter could be damage. Take a look at the sensor area and see if there is some stuff that it's not where it should be.

I don't see any stuff where its not supposed to be. The camera is working fine and I don't see anything when I take the picture its on the photo after.

A dSLR shutter creates a slit and drags it across the frame during exposure. If the two sides of the slit are not aligned or are in some way going out os synch, this can create the "shadow" you are seeing; at least this is my best guess absent evidentiary images :-(

You need to take it to Mike once he gets back from vacation.

Thanx all! I'm going to check with him on Tuesday Janine. He's not on vaca just yet...

maybe a stupid thought, but do you use a lens hood?
04/15/2017 10:09:56 PM · #14
I do Georges. But I did try other lenses without the hood also.

What's your shutter count? I hit the 65,000 shots on my 70D after 3 years, and still all looks fine.
04/16/2017 11:51:22 AM · #16
I am trying to find the shutter count. Can you tell me how to find that Georges?

you need to connect the camera to your PC and run this software

Look at the serial number of the last shot in the EXIF -- the image counter resets at 9999 but the numbers preceding it in the serial number will show how many times it has been reset (starts with 100).

' . substr('//images.dpchallenge.com/images_portfolio/0-4999/1031/120/Copyrighted_Image_Reuse_Prohibited_1198553.jpg', strrpos('//images.dpchallenge.com/images_portfolio/0-4999/1031/120/Copyrighted_Image_Reuse_Prohibited_1198553.jpg', '/') + 1) . '

In this case the counter has been reset nine times, so there have been about 93,000 actuations.

ETA: In thinking about it some more, the serial numbers may start with a "prefix" of 101 (not 100), so it may be eight resets and 83,000 shots ...

Thank you! Will check that out when I get home today!

Good morning! Thank you for your help with this. I ended up calling Canon and sending it in to them for repairs as it is less than a year old. They found a broken shutter assembly. They replaced the shutter assembly and the focus screen... all under warranty! I sent it in on Tuesday and received it back this morning! Yay! To say the least I am very happy with Canon's service and that I have my camera back!

Great outcome!
