I SO agree with this...

I had a 40D, and it had a usable ISO of 100...that's it!

I moved up to the 7D (and i do love it), but despite tons of advertising guff about high ISO, I maintain it has a usable ISO range of 100-400!

Even at ISO800, it is pretty poor, and getting up to ISO3200, it's all but useless...

Disagree completely. It's usable up to ISO 5000 in a pinch, if you have an image properly exposed without anything important in the shadows. Here's a shot I took at ISO 1600.

ISO 4000. I generally consider ISO 4000 the usable limit.

That's probably because you don't blow your images up until they're the equivalent of a 6-foot wide print being viewed with a magnifying glass from 6 inches away.

In this situation I was much more limited by the lens than the body anyway. 250mm f/5.6 in a night rugby game. Had I some f/2.8 tele gear I could likely have got the ISO down to about ISO 1600... stadium security would stop you at the door with such gear however unless you had a press pass.

I just bought a 7D and find it usable right up to 12,800.

I added a grey card to help with white balance and some dark clothes to add some shadow area.

7D ISO 12,800 test (external link) by ScubaDude1960 (external link), on Flickr

definitely usable to 12,800 ISO depending on the exposure

you're crazy if you think you couldn't go above ISO 100 on a 40D...

Not everyone has the same idea of what noise is acceptable and more have little skill managing noise in their images. For me ISO 3200 on my 40D delivered very nice pictures and ISO 12800 on the 7D is not a problem either, but that's me.


Not sure why, but call me JJ.

I should have appended "on non top-of-the-line" bodies. My guess is 256,000 on the 7DII will be a joke.

Well, 256K on an APS-C collects about the same light as 655K on a full frame. Both could be usable for small web images if Canon could completely eliminate banding noise.

Some might consider your standards to be a neurosis.

I guess film was not usable at all?

Oh I thought it was a case that some people expectations are set to high.

I DONT manage noise in my images, AT ALL, and i still use 3200 on my 7D.. I rarely use it at 3200 (Not because of QUALITY but because i just dont use ISO3200 much lol I wouldnt hesitate to use 6400 if i had to, I just dont -have- to very often) but when I do I have no complaints

Heres ISO3200 in a pitch black room.. Nothing wrong with the noise performance here..

I do NO noise reduction, if anything my processing makes noise MORE apparent...

Sorry for adding the zero before. My head is in the clouds sometimes.

Shooting street at night, where the ambient light is there but not great, I found 1600 the highest I could go (acceptably) on an APS-C camera. I used a 30D and a 50D. Not extensively, but enough to know I would not go above 1600. However, AFAIK, ACR/Lightroom's latest NR algorithm is noticeably better than what was available at the time. This could have quite a large bearing on the output.

FYI, I used to run a 30D and I agree that 800 was really pushing it and 1600 was bad, The 7D handles high ISO noise FAR better than the 30D...

I have no experience with the 50D itself, I have used a T1i which uses the same sensor and the 7D's ISO performance is far better from the limited use I gave it...
