Hi all, a friend has loaned me a NEX-7 for a while but I have no manual to work from ... the only thing I can't seem to figure out myself is mounting a M lens via a Kipon L/M to NEX adapter. The camera says there is no lens mounted and doesn't allow shooting.
What settings do I do to enable shooting with adapted lenses? Step-by-step instructions would be most appreciated.
Thanks,

Yes, Ron, I tested for diffraction with a Summilux 50. Basically, I can see no difference between f:4.0 and f:5.6 that I can be sure of. F:8.0 is definitely "hit" by diffraction, though. My preference with the Lux, leaving DOF and bokeh aside is to shoot between f:2.8 and f:4.0.I've been doing some testing with the D800E and ZF.2 glass lately, and I've noticed that with most lenses, maximum image detail is reached at f/5.6 and degrades at smaller apertures due to diffraction.
I haven't done any such testing (i.e. aperture series) with the NEX-7, but due to it's smaller pixel pitch compared to the D800E, I am now thinking that it might peak rather earlier (around f/4) - as long as the lens can deliver maximum detail at that aperture. Then again, the AA-filter may blur the distinction between f-stops in the f/4 to f/8 range (quite literally).
Have any of you done aperture series with high-quality glass on the NEX-7? I'd be curious to hear your findings!
TIA,
Ron
Edit: I'd like to add that my purpose here is not insane pixel peeping. What I noticed very clearly with the D800E is that at the optimum aperture, the increased detail results in an image that shows high micro-contrast and therefore looks more clear and crisp. I think this is what is called the '3D look' or '3D pop' by many. I had never seen it as clearly before as I have with the D800E. As you close the aperture further from f/5.6, image macro contrast increases (if the subject is three-dimensional, due to increased depth of field), while micro contrast decreases. By f/11 to f/16, the image looks flat and un-engaging compared to f/5.6. The difference is quite remarkable!
One can only imagine what that would have looked like with the DP2MFound some very bad aliasing in the pic above
