Am I looking at the same pictures as everyone else?
I\'m actually pleasantly surprised at how good some of the wides are on the A7. The ZM25 and ZM21 both look pretty good to me: about as good as my CV15 on a NEX. The color cast isn\'t too bad, and there\'s definitely detail in the lower corners (obscured a bit by the vignetting, but I\'m pretty sure that could be easily fixed)
I think there\'s definitely some misfocusing happening on the wide-aperture shots, so I\'m not too worried about those.
The tests I did with the ZM21/2.8 on the a7 frankly look very bad, if you\'re into infinity landscape images. It will need stopping down a fair amount.

Would be interesting to see a stopped down landscape shot with ZM21 on the Leica M9. Anyone knows how to find one fullsize?
Please see my 4-way 21mm shootout on the M9, including a subset shot on the NEX-7 and GXR. There are full-fez downloads with samples through the full aperture range up to f/11. On the M9, the ZM21 had color shift problems until the more recent firmware versions, but still probably isn\'t perfect. It also has field curvature, which means flat, frame filling subjects result in soft edges/corners until around f/5.6. Overall it\'s a really good lens, especially stopped down a bit.
