I originally used your article a year ago before a trip to Japan to help purchase the Zeiss Loxa 21/2.4 and it has been spectacular - really pleased with the decision helped by your article! :)
Just reading about this new Voigtlander - seems to be getting quite a few well received reviews! After this particular comparison, just a couple of questions:
1) Have heard a fair bit about sample variation on Loxias in addition to field curvature effecting things - assume your copy is good / still the same from the original review? Also if due to the field curvature on the loxia - assume this explains why it's not performing as good with this "oblique" perspective / focus point? ( although left @ 2.8 seems to be quite different on the lox
2)The loxia shots look to be taken with a bit less available light / reflective ambient light - just wondering if that could make a difference in lens performance , and explain part of the difference ? Also noticing on the right side (the sandstone bricks) seem to have a bit better highlight rolloff on the Zeiss 21 - wondering if that is a colour rendering thing or again the ambient light changing shifting tone?
3) Would love to see / get your thoughts on how the Loxia compares to the Voigtlander in regards to chromatic aberration , colour control and flare?* *(often use the Loxia for film work as well as photography - so these elements are just as important as resolution / micro contrast to me :)
Sorry for the long read ! - just really interested & yet have been very happy with the loxia 21 ! I still wish Zeiss would bring out a premium FE / Mirrorless line - perhaps APO 1.8 / 2.0 high performance yet fairly compact primes... one can dream eh! :)
Thanks again & keep up the fantastic work !
DIGLLOYD: I have seen no sample issues with any Zeiss Loxia lenses—highly unusual. However, there is always some variation and no process is perfect.
Lighting with comparisons vs evaluation: I always take this into account and I specifically address field curvature in my MemChu oblique comparison.
All wide angles have some field curvature. Frequently it is pveripheral forward field curvature for wide angle lenses but it can be the reverse, or wave-type field curvature (more common in fast lenses).
I’ll bea addressing these questions above more as I shoot in the field—I’m in the Eastern Sierra as I write this.
