Ridiculous iso 25600 with the Canon 5D MK III sample images


I’m still deep in the heart of a time lapse motion project, but while my 5D MK IIs have been running I’ve had the chance to experiment with the new MK III. So far all I can say is wow. The image above is an example. It is shot at 1/13 second at f 1.4 iso 25600. The thing is it is so dark that I could not even see the camera, I had to focus on the red led on the battery.

Check out the 100% detail below, this camera will open up photographic possibilities we haven’t even thought of yet.

Obviously 25600 isn’t something that you could use all the time, but it could produce publishable images. Turn the iso down a little bit and the camera begins to really shine.

Check out iso 3200 below.

Not bad huh? It only gets better as you go down.

The most obvious thing this camera might change for me is my cave lighting package. It can get a whole lot smaller because I can be working at iso 1600 instead of 400 where I am with the MK II. Big rooms won’t be the challenge that they were when I shot everything on Fuji Velvia. Early morning aerials are going to get less stressful as well.
