I would not be able to justify the money/performance ratio for the new ultron on the A7 bodies. A mod or 240, maybe.
I would advise Cosina to study the Sonys closer because they would sell many more with a better tuned lens (meaning tuned for the Sonys). The competition at 35 for M is pretty strong, but the field is much more open on the FE.
i don\'t know, phillip\'s last shot looks pretty sold for landscape and significantly better than your cv 35/1.4 seems to perform in the outer 1/3 of the frame. the bokeh of the f/1.7 is much better wide open than the 35/1.4 at f/2 as well.
I regard the Nokton on the un-moddifed A7 as highly quirky with large dips, which can be seen in the A7r landscape, above. I don\'t consider the 35/1.4 as a landscape 35 for M9, much less a stock A7.
The Ultron landscape above is quite weak on the edges at F/8, to my eye looking at the full. To me, the A7.mod w/ CV 35/1.4 is better, but I might be wrong. I would expect the Ultron to out-perform the Nokton; both on a A7.mod at F/8. But on a stock A7x it does not appear to me a remote competitor to FE 35/2.8 as a nice crisp across the frame landscape lens, with no big dips at 5.6 or 8, and strong edges. As say, the ZM 35/2 performs on the M9.
But that\'s a view from a single Ultron landscape, so perhaps some more will appear to show the Ultron better than it seems to me in that shot.
Does no one else see a loss of sharpness along the edges of the Ultron landscape?
there is a sharpness drop on the corner, i don\'t really see much of an edge drop off if you follow a line of equal subject distance. the zm 35/2 has a corner drop on the m9 too. i\'m sure the three zm lenses probably all perform better on the m240 than this on an unmodded a7, but it looks good enough for me not to care about getting sharper. the FE 35/2.8 and loxia both look very unattractive to me because i use 35mm lenses mostly at short to mid distance and i find their drawing style a bit distasteful (i really don\'t like the loxia).
OK I take it back
I went back to the fulls again, comparing the Ultron also to my CV fulls from the 1.2 (stopped down) on the mod. Philip\'s landscape is right with it and maybe better out to the sides.
So maybe this is now the best RF 35 for the A7. Next question: colorcast?
