I'm a happy bunny! :)

For the past 2 years I've been struggling with a bit of backfocus with my 400D after I changed the focus screen. I knew I had to focus slightly in front of the subject, but it was hit and miss. More often than not I misjudged it.

So recently I made the effort to correct it. I followed Rick Oleson's advice to stick a sliver of Magic tape on the brass spacing shim under the screen. Results have been really spectacular, thanks Rick!

Congrats, Peter, the tape certainly proved its name!

Congratulations, this type of fixing is a lot hit and miss and you seem to have nailed it the first time.

Looks like a spot-on result, Peter.

Thanks everyone. I realised after posting these pics it would have been better to select a close-up and wide open. These two, picked at random, are both around infinity with small apertures, so they don't prove a lot. I'll see what I can do next time.

Thanks to your prod, I decided to go for it as well. Thanks, Peter.
I had the EE-S in my 5D and I was pretty happy with it. But I am so used to a split image or a mirco-prism ring that I missed the odd shot because of a misfocus.
Henry, whom I bought the 5D from, had included several matte screens, one of those a Leica-R screen. Well, I installed this one and it's fantastic. The micro-prism ring is visible a little below the AF-mark ring but that doesn't bother me. Neither does the little dirt that is visible at the very top of the finder now.
The most important thing is: the cam now is spot-on with an f/1.4 lens!!
Yiippiiieehh!

Thanks, Peter! Without your thread I would not have done it, I guess.

Well done! It really does make a difference when it's accurate - you have more confidence. I thought it would be OK to focus on the subject and then move the top half of the image a tiny bit to the right but, as I said, this was only succesful some of the time.

Now I see I need to clean the sensor! Smile

I took some shots in the garden today, just to test it at open apertures (f/1.4 to f/2).
And really, the micro-prism ring is more accurate than the AF - and the 5D has quite a good AF system.

I just needed to adjust the meter, which is easy enough to do with the EV-compensation. Wink
