The point is, of course, that auto-everything has nothing to do with having a choice of more than one lens.
If the OP would follow your advice, and go for a Rollei TLR, he would be stuck with a system that allows him to use one lens, and one lens only.
All you need, one lens, you say. But that's not true!
If you need more, you say, you cannot be an artist. That's even less true (if that would be possible)!
Why did you buy a Mamiya to use Zeiss lenses on?
And how about those Leica lenses?
