After getting my 1D Mark III, I did what I have done with every new camera body since buying my first SLR in 1986 - I took it to the zoo. Melbourne Zoo has a reptile house; like most reptile houses it is dimly lit. This gave me a chance to try out the ISO 6400 capabilities of the Mark III.

As an exercise, I limited myself to just one lens for the entire visit - I took the 200mm f2.8L prime, partly because I recently read a critique that described it as amazingly sharp, and partly because I have always felt the need for a longish lens at the zoo. This lens is fast, sharp, and fairly light.

Anyway, here is a shot of a green tree snake, shot through glass at ISO 6400, f2.8, 1/500. Note that the same shot at ISO 1600 would have been 1/125, a little slow on a 200mm lens... The 100% crop shows that the image is surprisingly low noise (especially for ISO 6400!).

The uncropped image:


A 100% crop:


Not a scientific analysis - just thought you might be interested in the shot.

BTW: I had no focussing issues with the Mark III, but it was a cold cloudy day.

As you can imagine, I intend to conduct some more experiments with ISO 6400. I think it makes available light photography more interesting...

I'm also keenly looking forward to the 1Ds Mark III announcement. I suspect it, too, will support at least ISO 6400.

Your results are similar to other examples I have seen of this awesome new camera. If you run Noise Ninja on the image it will virtually eliminate the noise. I can't wait to get one for available light shooting. Just hoping they get the focus issue fixed soon...

If you are doing available light photography you should be able to avoid the focus issues - they are mostly reported with bright light and warm temperatures, which are a long way from what I'd call "available light" circumstances

But yes, I'm hoping it's fixed soon, and that's it's a simple firmware fix. I'd really hate it to be something they have to fix in the repair shop, 'cause I don't want to lost it for a while.

The more I use it, the more I ponder what they are building into the 1Ds Mark III...

That's really amazing. I expected a lot more noise than that. I may have to re-think my "Nikon for life" position.

Suddenly, I can't wait for the 1Ds3 to be released! I heard it will have a 5fps frame rate, and 20mp CMOS, with a 6mp RAW option too! I just hope I wasn't B.S.'ed!

Thanks for the post, and enjoy your great tool!
