That\'s not going to solve the problem with this particular lens, at least based on what I saw from the one I tested.
What would be interesting to see is a comparison between the ZM 35/2 Biogon and the Loxia 35 on a modded A7...and for kicks, maybe toss the ZM 35/1.4 into the mix.
That\'s kinda what i was thinking, too. The Loxia can\'t really be the same, but I appreciate the trouble when there is no good infinity stop: for me finding the best infinity focus on the A7 is truly a migraine inspiring PITA if you really want it perfect.
But I did a serious attempt with the ZM35/2 soon after I got the camera back: this is f/5.6 a7m_zm35-2_f56 (1 of 1) by unoh7, on Flickr
I also have the same view at f/2 and f/4 but the edges are not in. Anyway what I love to know is how does the shot above compare with a Loxia at f/5.6 on the stock A7 with similar distance and detail?
A close look at the shot above shows the Kaaragon pretty impressive to my eye, fully landscape capable at this aperture with the typical extreme corner drop off also seen on the M9, but otherwise......good
This lens is still great close in on the A7.mod, so where does the Loxia stand to this benchmark?
It sounds like the bet Steve and I have will take some time to settle
One more tidbit; the same scene, more light, and the M-Rokkor 40/2 at F/4 ! 40:2 f:4-001 by unoh7, on Flickr
You guys tell me which wins on the edges in those two samples (with both at f/8 the Rokkor has it I think).
I forgot how nice the little 40cron clone really is, I will have to take it out tomorrow.
Wait one last contender, the CV 35/1.4 at f/4 also!
