Ok,.. this is MY crosshatch on my 5DmkII

Yes,.. i've read some of the other posts,..
Yes,.. i've seen the images from other people
But my problems seem different.
Has anybody experienced what is shown below - i like to call it mouse maze pattern.

Things that don't make sense:
- it wasn't low light
- it wasn't low ISO
- i didn't push the blacks or contrast

ORIGINAL

can you post the whole photo pls?

I just added the original to the post.

From what you posted up here it looks slightly under exposed to me? The pattern you see in the picture looks like the same pattern that is on the sensor. Does this happen with all your shots or only some of them?

Take Care,
Cheers, Patrick

Thanks for the feedback.

1. It might have been slightly underexposed but it shouldn't cause this problem. I have two similarly underexposed photos and one has the crosshatch obvious at 100% and the other doesn't.
2. I'm still trying to answer that question. Suffice it to say, it does it all the time but at varying intensities or perhaps seems that way depending on the shot and subject matter. Sometimes i don't see it at 100% but will at 300%. But when it's at 100%, it's really obvious.

I called CPS and they had me update my Firmware to 2.0.4 (i was previously at 1.0.x). I haven't done enough test shots to verify results yet.

Yikes, I hope the firmware fixed it. If not it appears to me to be a sensor problem.

Looks like the world's most perfect example of aliasing. Here's a really useful article on this:

That is not right. send it in.

woah thats really weird, just strange, never seen anything like that, send it back to canon immediately, while its still under warranty.

Slight underexposure shouldn't cause any problems. For that matter, moderate underexposure shouldn't, either - underexposure is only really a problem if you try to bring it up in post.

I would exchange the camera or get it serviced if the firmware didn't fix it. Something's wrong with the data processing or the AA filter or something.

# Exposure Time (1 / Shutter Speed) = 1/100 second ===> 0.01 second
# Lens F-Number / F-Stop = 14/10 ===> ƒ/1.4
# ISO Speed Ratings = 400
# Original Date/Time = 2010:04:21 19:07:15
# Shutter Speed Value (APEX) = 6643856/1000000
Shutter Speed (Exposure Time) = 1/100 second
# Aperture Value (APEX) = 970854/1000000


Seems a bit weird

Had a look at my images, at 500% can't see any maze patterns, just the pixel blocks

O_o That is some weird stuff, you should take that in, looks like a sensor problem.

It does look kinda cool though

Wallpaper?
