Actually it's a fairly minor difference with major implications. Most pre-A
lenses are adequately linear up to f8 or f11 and only become non-linear at
smaller apertures.

Now that's interesting!
That's must be indeed the major mechanical difference comparint both
lens types.
Thanks for this feedback!

Vic,
Late reply, but here's my take.
The A 50mm lens can be used fully automatic on DSLR's.
The M's require you to press the green button to measure exposures.
Makes the A easier and faster to use.
Simple as that...

Hi,
OK, obviously I do know that A-lenses have an A-modus, allowing the
camera to set the aperture (shutter-priority modes), while M-lenses
always require the aperture to be set on the lens.

I have four M-50/1.4 and two A-50/1.4 (you can never have enough
fifties). Here's a summary of my findings:
M:
- better bokeh
- better build quality
A:
- better sharpness from 1.4 to 2.8
- perhaps slightly higher con

Hi,
OK, obviously I do know that A-lenses have an A-modus, allowing the
camera to set the aperture (shutter-priority modes), while M-lenses
always require the aperture to be set on the lens.
But being in persuit of a 50mm f/1.4, I notice that the A-model is
priced at least twice as high as the
