I have just picked up a nice MX and need to put a 50 on it. My old
kit was a
Spotmatic and an SMC 50/1.4, now stolen. I use this mostly to
supplement my
Leica M outfit, filling in the gaps between it's shortcomings, and
as a backup.
I'm interested in the early "K" 50/1.4 because it appears to be the
nearest
replacement to the lens I've been used to.
The lens spends most of it's time wide open, close up, occasionally
with a
short extension tube. Ultimate sharpness is not my main concern.
I'm interested to know what people think of the differances between
the K lens
and the M version, especially regarding overall wide open
rendition. I remember
some discussion in the past about this, but the archives don't seem
to offer
much help. I recall many people regarding these lenses as virtually
identical,
but a look at the cross sections would seem to tell a different story.
Any thoughts?
