Skopar 21 vs 21P, any difference in handling?

[froyd]

The screwmount and the M-mount 21mm Skopars are identical optically, but feature a different barrel design.

If you have had a chance to handle both, can you remark on the difference in ergonomics?

I've used the 21 screw mount vs. the 24P - which is similar. I prefer the P version, very slightly - the thumb tab focus isn't as easily accidentally shifted as the pin in the 21 screw mount. But, with that said, the aperture ring is easier to accidentally change. Kind of a wash in the end, but I still give the edge to the P.

That's pretty much it. They are both very compact, quick easy to use lenses.

I thought as much, and your feedback settles it.

Since the difference is very slight, I'll go with the screwmout. I'm a sucker for chrome lenses and I think the P is only available in black.
