It's an awesome lens, used it on my GH2 and my D700. Tack sharp, wonderful colors and bokeh. Build quality is excellent as well - poor man's ZF2 :-)

D700, wide open:

Nikon directiion, but Canon mount also available.

So buy the old or the new one :P

What kind of adaptor for this to m4/3?

@last_SHIFT: Not too odd, since both Zeiss ZF2 and Voigtländer are made by Cosina.

Thanks. Then how bout this. Nikon G or F adaptor, or would it technically work with either?

-asking because I'm not clear on whether the aperture control would effect the size of the adaptor and thus change the width of the lens.

Just an FYI (as I've recently picked up the Voigtlander Ultron 40mm f/2 and the Nokton 58mm f/1.4 in Nikon mount): not all of the new SL-II lenses have the "Nokton 25mm" focus ring style; mine has a rubber grip that I find much easier to do wide focus pulls with.

Both are gorgeous lenses, and make a perfect set with the 25mm f/.95 using the "f-stop rule".
