A clear "must"

I barely had hingekriegt an image that I have not had zurechtrotieren is unfortunately lost on the PC which part of it. Here the new Focusing Screen provides really good service and my results have become much better.

The installation is really a no-brainer and absolutely critical. The tweezers is necessary. The work environment should be as dust-free as possible - otherwise annoys you about lint in the viewfinder.
I have the installation carried out in the bathroom - with a respectful distance from the cat. In 1 minute the thing was in there.

Actually, everything was here also already said. But I want to mention again that the focusing screen does not only fit in the 40d but also in my 50d.
