[Leica] Leica SL lens question

[hopsternew at gmail.com]

Bob I should have more correctly said that the ROM functions with the R lenses are not relevant with the M lenses and there is no mechanical linkage for aperture operation with M lenses as we know.
And yes the M optical dot coding is relevant.
My love for the 24-90 and OIS is not undiluted I confess, or at least the jury is still out for me.
The way I use the SL focus is to use a single AF point in AFs operating in MF with the rear button (as I was taught for fashion/beauty with DSLRs)
But I don’t always see what I think ought to be bitingly sharp even though I am typically f/9.5 and be there for studio.
It certainly can be but maybe I need more practice. To be fair when you are seeing S and SL files from same environment at 100% on your editing monitor.....
Maybe the OIS is making my slower exposures sharper but I am not noticing it. It’s a thing to remember when I go to tripod though.

As an aside to that let’s see if all of those acronyms provoke comments!

Handling wise for me the SL-and 24-90 doesn’t feel appreciably lighter that  the S with say 70 and the S is much better ergonomically as far as holding comfort. That changes if you put the battery grip on the SL
Without that it is the sharp lower edge that bites me a bit after an hour or two and a few hundred frames. Again it obviously it depends on how you are shooting.  Sitting or kneeling on the studio floor hand-holding that thing, align focus point compose shoot, maybe a frame every three seconds for sets of 30 or 50. Maybe 300-500 frames in a couple of hours, more if I am shooting with both cameras.

My M adapter has contacts.  Also, the lens information on coded M lenses is passed through to become part of the EXIF information. 

Relative to Aram's question, there are a couple of things that I like about SL lenses vs third party lenses:
1.  SL lenses have OIS. I find this is very helpful in keeping the ISO lower and the shutter speed higher by a couple of stops. 
2.  The autofocus is pretty impressive, but I'm not shooting sports or moving animals, jus grandsons...
3. Have you added the weight of the SL/R or whatever adapter to your calcs?
4. The SL 24-90 isn't really that large. The hood and small body make it appear that way. My bride thinks it looks, overall, smaller than most N & C cameras she sees. YMMV
Good luck,
Bob
