p.1 #1 · p.1 #1 · Best ISOs ?


I have been using ISOs that I found on a chart mostly stating the best ISOs noise wise were typically 1/3 stop lower than full stops. EG. 320, 640, 1250,...
Now I have two new cameras a 5DsR and a 5DIV.
Is there any updated info that I can use?

What are the best ISOs for these cameras? Should I even care?

The 160, 320, 640 ISO settings are not relevant to the modern bodies. Shoot the 5DsR and 5D IV as you like.

Agreed. If I do my part, I can get very usable ISO 6400 on my 6D.

I shoot at 160 whenever possible, and I've been doing that since I've owned a digital camera. I don't know where I originally heard that it works, but I shoot at 160 and 320 over 100 and 200, and never questioned it. It was working for me, and it didn't hinder my style or method of shooting, so I kept doing it. I was curious as to why I do that and found this post. ISO in multiples of 160

I guess the simple answer would be use the ISO that allows you to take the picture.

The "best" ISO from the viewpoint of image quality is whatever your camera's base ISO is. At base ISO, each pixel records maximum signal. Higher ISO records smaller ranges of light. Physics aside, the best ISO is the one you need to get the shot!

The 5DSR eliminated the bumps but the 5D4 brought them back but not as bad as the 5D3. Anyways I wouldn't worry to much about it.

The significance of any difference between whole and 1/3 stops is so trivial as to not be worth worrying about.

Pick your ISO, shutter speed, and aperture based on photographic requirements and intent.
