You'll lose the aperture information in the viewfinder with the M lens,
(but then you didn't have it in manual mode anyway). Some extremely
picky people on this list think there's a huge difference between the M
and A versions. But they are the same optical design, the coatings are
similar, the only difference you're likely to notice is the superior
build quality of the M lens, (if you get another 1.7). I'd stay away
from the M 50 f2.0, but that's just me.

Hello.
Currently I'm using a 50mm 1.7 A, an I like that lens. I'm looking for
a second 50mm lens because one lens can not sit on both bodies (ist
and MZ-5) at the same time. (And I hate swapping lenses.).
I know an M lens won't function properly on the ist, but how does an M
lens function on the MZ-5 ?
Is there a big difference in quality between the 50mm M and 50mm A
lenses ? (There is a big difference in price :-) )
Thanx.
Johan.
