My eyesight (with glasses) is very good. I can read the most bottom line at the usual doctor-test. In the last days I tested the Canon Ec screen with my new DFA 50/1.4. I like to say manual focus with this screen is better or the same than autofocus. The autofocus works very well to the point the camera likes to use. But with manual focus I focus to the point I like for a good picture. Of course this is not important for 2.8 or slower, but for 50/1.4 or 85/1.8 I prefer the manual focus. But before that is was much work to calibrate the screen to my camera!

Perhapt it would save me 10min if you could provide a STEP file. :-)
But I wonder (and I can use 3D-printer for 10kEur) how you can print something dimensionally stable to 0.05mm or better. I fear the idea to sand it down a little because of the dust. Oh and for people without a printer, there are company (like shapeways) that are printing for you. In this case it is possible to print in metal.
However, yesterday I use the new focussing the first time with my old SMC 200mm/2.5 in the zoo. I still recomend this to everyone. It made the fokusing live much easier!

Only a short notice...
I replaced my focusing screen by a Canon Ec. I had to remove the 0.45mm distance frame and cut myself a new one from paper. I had to do it four times with different papers but now it works perfekt. I think I am now at 1mm backfocus with a 85/1.8 at 90cm distance. It was some work to calibrate it with the different papers, but I can recomend it.
