Re: Views on the F 70-210

[Joe Wilensky]

I really like my F 70-210 -- it feels a bit better constructed than 
most of the FA lenses and it does perform very well. Very nice 
handling on a PZ-1/PZ-1p. I haven't tried it on smaller bodies.

The FA lenses have the encoded MTF data (tells PZ and later cameras 
the lens' optimal quality aperture if you select that exposure mode) 
and also tell the camera what distance the lens is focused at, which 
can enhance the camera's multi-segment metering decisions and program 
mode choices. The F zoom lenses do communicate what focal length 
they're set to, though, which is useful for shutter speed selection 
in program mode, among other things.

 > Still, I am curious - what is the difference then between F and FA
 lenses? Something to do with the way FA lenses "talk" to the camera
 body?
Not a clue, sorry.

 I am sorry I am taking this subject off-track, but I hope noone is
 offended.
Gads, with the amount of off topic on this list, it's refresshing to have a
camera related discussion...
