My 100/2 ZE came in, and here is just a test shot from last night. I've head the 100L before, and it's very nice and sharp, but you don't really get that 3D effect as with the Zeiss.
Focus is a bit tricky. I've set the "AF point display during focus" menu option to "focused" and this helps (the AF point lights up briefly when getting to focus). I guess there is no option to have that point light up continuously when it's in focus? Yes the green dot at the bottom does that, but when I take the eye down, it's hard to keep the frame composed. Still, this is a bit better than with the Nikon which has no manual focus indicators within the frame.
