Is it time for a new shutter?

Is this straight from the camera, or after the raw converter?

Note: I was testing Capture One 4 the other day and one of my images that opens fine in DPP & Silkypix looks just like one of these in Capture One. Strangest thing.

I have seen some earlier posts with this similar problem, it suggested a sensor problem rather than a shutter problem. Let see what other's opinions are.

Those don't look like shutter problems. A shutter problem would result in black/darkened bars uniform across the entire width of the image, not weird color problems in quarters of the image. Your camera is probably mechanically fine --- the problem appears to be on the digital side.

I agree with Spyro. Either the card or the sensor itself.

Was a raw converter issue, thanks for asking.

Whoops ... not a raw converter issue. The .jpg straight from the camera looks fine but the RAW does this with three different converters. Maybe it is the card ...

Last time IIRC it was faulty memory, not the shutter.

Doesn't make sense that the camera can process internally to JPEG, but cannot produce a native RAW file.

Format the memory card?

Try another memory card?

Reset the camera to default?

Remove all batteries from camera?

Reinstall the firmware?

Use Canon DPP?

I've seen that when you fire a sequence and you turn the camera off before it finishes writing to the card.

Definatly a card problem.

What brand of card are you using?? and where did you buy it from??

My thought exactly, so I'd guess it's a card issue.

It's more likely a card reader issue.

Sometimes updated drivers will curse this, more often it's the reader itself.

I've seen the occasional file similar to this from all my cameras, but once or twice it became a regular experience and dumping the reader fixed the problems.

It can be frustrating as from one camera, same card same reader it may be fine, another camera, not so, thus leading to one suspecting the camera ~~ whilst the camera can be responsible for this on very rare occasions, it's usually the actual card reader itself.

Extra: BTW, if your files are still on the original card, they should transfer just fine with a new reader ...

What brand of card is it? I had a 1gig no name brand that did the same thing. So I changed to Extreme III's and have never lost an image since.

Sandisk Extreme III 16 gig purchased at Amazon IIRC. Will try a different card reader, files are still on the card. Canon DPP conversion looks bad too. Thanks for the suggestions.

Only time I ever had this it was the card.

Absolutely a memory issue of some sort, either the card itself, or card reader.

That doesn't look like a shutter issue- a shutter issue would be indicated by some portion of the image being black. Your sensor may be the issue (although it doesn't look like it because there's no distinct pattern in the corruption of the images). Something is getting lost in translation, either the A/D converter isn't encoding properly, the processor isn't handling your image correctly, or your card writer is malfunctioning.
