When working with raw data, there is no point in using ISO 3200 with the 5D, as that tops at ISO 1600. 1600 with -1 EV bias yields the same noise without reducing the DR by one extra stop.

Does anyone have actual proof of this? I know expanded ISOs are just regular ISOs pushed through firmware, but does anyone have proof that shooting at the max native ISO at -1EV and then pushing it +1 in post is better than shooting at an expanded ISO?

Panopeeper has done extensive research on this, so he has work posted on this site to that effect. Tony

bsaber I have no idea what's going on  3,536 posts Likes: 3 Joined Aug 2007 Location: Los Angeles, CA More info | 3200 on the 5D is perfectly fine and usable if no "severe" cropping or viewing at 100% is involved. The following pic was taking at 3200 without noise reduction. For this shot the noise wasn't going to be an issue to me but camera shake was so I opted for the higher ISO.

Perhaps you can clarify this statement with another one of your posts[here] as I seem to read a contradiction to what I just quoted.

It depends on the exposure; see https://photography-on-the.net/forum/...d.php?t=626474 (a well-exposed image can be pushed much more than an underexposed one). Gabor
