RE: [Leica] Ricoh GR 28 f/2.8 caution

Mike,
Probably not too far off topic as the lens is available in LTM.
I've only recently noticed (since the lens was returned from the magazine   
that tested it) that the lens seems to have two irises (irii?).
Tom A. and anyone else who has one, is this so? Or am I seeing things?
Mike, does your camera/lens seem to possess two... whatevers?

My GR1 does not have any noticeable pin cushion or barrel distortion. One
of my standard checks on any new lens or camera  looks specifically for
this. I am very satisfied with this and all other aspects of the camera.   
My
caution would be that the passive autofocus, while more accurate than
active, is more picky about what it will or won't focus on. Since the   
logic
is not focus priority it will let you take the pic even though it can't
focus. It does warn you in the view finder that it can't but in the heat   
of
the moment I tend not to notice.

PS sorry if this has gone too off topic.

Could this distortion actually be from not holding the
camera perfectly level?

I also bought a GR1 last year and am very pleased with
it.  One thing to watch out for - once, the autofocus
sensor failed to lock on to a distant target - not
because it wasn't contrasty enough, but just too small.
I should've used the infinity setting.  Anyway, it's
nice to be able to select apertures, exposure compensation,
metering area, and to see information in the finder such
as shutter speed, focusing range, and parallax.
