Canon Lenses Eos
Is there an adapter to use 4 / 3 's lens of my Canon EOS?

I only find the adapter that goes the other way around, and always micro / 3 no 4, the regular one.

I do not think there are adapters. *** In answer to your question above landscape. The Mamiya RZ67 Mamiya 7 or are wonderful cameras landscape. However, having said that, I prefer SLR cameras, because I can see exactly how the lens polarizer is affecting the image in the viewfinder. You have to guess with a rangefinder.
