Then I went into the lowest DSLR class with the EOS 400D to time to sniff DSLR air. From there all my photos were wrong. The cause was that you hold a DSLR quite different in his hand, like a compact. The Compact keeping both hands firmly on the "Body". The DSLR with one hand most often on the lens. This is an important sensor, the parallelism of the hands on the body falls away.
Now I have an EOS 40D and am glad that you can change the focusing screen. So quickly bought the Ef-D, and today it arrived.
The installation is very simple:
1. Position) Body without lens in dust-free Umbgebung
2. Open) plastic box ef-D and take pliers
3.) Carefully loosen the clamp above the mirror
4.) A frame can be folded down on the disc is
5.) With the pliers, remove the old washer and stand in the box
Remove and insert 6) new disc with forceps
Fold 7) frame
8.) The Ef-D sign in the camera, because the exposure is done BY the disc
I have put down to increased dust the body. Then fold (pfällt) the frame but down (then remains scarce but surely mirror stand) and the disc falls out. That's been a little silly of me. But there is nothing happens.
So Sets better towards the body.
Anyone who has ever worked with a fingernail scissors, enough technical know-how have to switch the disc !!
For me, the AF points match 100% !! These Ef-D disc is so full of charm and as others have said, the grid is fine enough to it to ignore, if you do not need!
