Hi all,

I saw a review about this expandable ISO 12800 on Canon 50D, please can someone explain to me how and when do you use it and is it something already built in the camera? :roll:

Thanks in advance!

You should really read the manual :)

C.FnI:Exposure-3
that's where you find it and enable it if you want.
default is off
But one doesn't use it if there is another way to take the shot.
Noise is terrrrrrible in that sensitivity range.

Why would you need it anyway? I saw that ISO 1600 on the 50D is not really usable,unless it's an emergency

The high modes (6400, 12800) are pretty awful looking on the 50D and very much a last resort use. The banding pattern that appears is hard to work with, and the bright speckles are tough for raw converters to handle well but they're better at it these days. Basically if you have even the fastest lens and the longest shutter time you can tolerate are not enough, then you might consider it. When I had a 50D, I found ISO3200 to be about my acceptable limit, with ISO1600 being a routinely usable setting. Needing to go beyond that was rather extreme.

I've only had the 50D for a few days, but I can also say that H1 and H2 are awful.
With max noise reduction on a RAW file in DPP you can remove most of the red speckles, but the banding persists and the image gets very fuzzy. Indeed a last resort
