Hi all,

I'm thinking of getting the EE-S focussing screen for my Canon 5D.
Now I've read numerous times that it's difficult to manual focus with F4 lenses, but what about F2.8?

I have the new 100mm F2.8 IS macro and I'm scared that focusing it will become more difficult as the current screen is optimised for F2.8. Or will I be able to manual focus more easily with the EE-S?

Thanks for the comments

I use a 2X tcon with my 135mm 2.8 on my 5D and EE-S screen installed without a problem.

The standard screen does not show DoF smaller than f/4 to keep the VF bright. The Ee-S screen does away with this to show exactly what the lens sees.

f/4 is perfectly fine, it is just darker than on the standard screen. f/2.8 will be more or less the same, you will just see the actual DoF, so you won't be missing focus as much when manually focusing.
