All true enough, Henning. But given a choice between those problems, and
not being able to get close, I'd take the problems. (Not to say that
they aren't serious issues. And of course that's where we may have
problems weighing the advantages and disadvantages of rangefinder v SLR
for wide angles. The RF is defininitely superior for focusing wide
angles; on the other hand, the SLR allows really close focusing. And in
that regard there is nothing to match the discontinued 21 f2 for the
discontinued Olympus OM series. I believe it focuses down to about 9
inches from the front element.

It's just that closer focussing makes all the problems with finder 
obscuration and parallax error a lot worse.

Zeiss can make the lenses focus closer, but it can't get rid of the 
geometric difficulties brought on by closer focussing. There has been 
a good reason why rangefinder cameras don't focus closer. Som P&S 
cameras focus closer, but with their slow, small, lenses and lower 
user expectations smaller viewfinders can be placed closer to the 
lens axes and sort of handle the problems.

The finder obcuration that Leicas have is miserable enough; the 
closer focussing of the Zeiss cameras/lenses just makes this 
significantly worse.
