Hi folks,

I was enjoying reading about the Zeiss Distagon T* 2/25 (here) and marvelling at the number of elements in the lens

when my attention was grabbed by the Zeiss article Manual Focusing with AF Camera Systems. An interesting and pretty well balanced summary which included the following links to some third party manufacturers of focus screens:
It had never even occurred to me that there were third party manufacturers of focus screens. :shock:

Has anyone any experience with any of these folks?

Bob.

Edit: I've updated the link to "intenscreen" and "brightscreen".

I have, I thought exactly the same when I bought my Zeiss lens. My eyes would need help focusing more quickly and accurately.

I bought mine from: (EOS 7D Ec-A)
http://www.focusingscreen.com/

And its excellent, you also get the tools you need for installing it as well as spacers to calibrate if necessary.
The only negative thing is that its not entirely centered, but its no practical issue at all.

I highly recommend changing the focusing screen on your camera if you like MF.

(The focusing screen changes no function on the camera what so ever, everything you had before focus screen change you will have after plus more.)

One thing to note though:

Your F4 lenses might appear less bright in the viewfinder afterwards. It does affect things a little in that respect.

I haven't tried a viewfinder on a 5D Mk II though - if it's anything like the D700 then you might be able to do without the split prism. I can manage without with the 2/35, so should be easier with a 2/25.

2/100 might be a different story though.

Yes, i use a split image focus screen in my 5DmkII, I purchased it from China through ebay, works a treat. (I'm sure i had a thread about it here many moons ago).

Using a Nikkor 1.2 AI-S, first on a Canon 7D with a Novoflex adapter, and then later on a Nikon FM3A, with its excellent focus screen, certainly showed me the profound difference that a proper focus screen will make!
