I notice he is also considering the Kolarivision Thin Stack conversion (my A7 is with them now)
Great that he included the ZM 35/2 one of my favorite lenses on the M9. Obviously the Loxia is killing that one on the A7 with stock sensor. Will be so interesting to see after the conversion if the biogon can recover some of it's glory.
Viktor is being quite polite to the Loxia, but I think many of would have expected Zeiss to hit it out of the park with this lens on the A7 series. My conclusion is the FE35/2.8 (which I have admired but don't own) is really "the one" for the A7 at 35, still. And alot cheaper since it can be had used.
The bottom line is that more than a year after the A7 release the serious lens choices are very very thin, when compared to Leica M, which offers at least 10 fantastic 35s of differing speeds and characters. A perfect Zm 35/2 goes for about 650 used today.

Of course the "fun" 35 choices for the A7 are unlimited. I quite like my FD 35/2SSC thorium:
