Hello.
I found out that it's not necessery to match camera lens to projector lens. But I thing there must be some worse and better lens of cameras for mapping. I want to buy Canon EOS 5d Mark II. Any lens sugestions and advices?

Depends on the projector you are using. Wide angle projectors will work better with a wide angle lens, etc. As long as the camera can see entire projector output and the camera settings are correct, you should get a good scan.
