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.

Yes, the M mechanics appear better.

But the deeper blue/purple coatins of the A provide a cooler, crisper, more contrasy 
result.  I've compared M & A before and personally find the difference is meaningful.  
YMMV.

F & FA lenses tend to be a pleasant mix.  Sort of a brown/purple cast.  (My F50/1.7 
and the FA43/1.9 are this way as is my son's F100-300.)  Good contrast and a little 
more warmpth.

M50/1.7 lenses often sell for $25-$45 and A50/1.7 units sell $40-$60.  Either is a 
real bargain.

Sincerely and without bullocks (What's a "bullock", anyway?),
