So these MTF's with the Sony A7* + ZM 35/1.4 are calculated and not measured using the actual sensor glass? Do you know if these were provided to Lloyd by Zeiss or are they his own calculation/ guess?

Drat! This all suggests that the lens won't be as good as I had hoped for the Sony cameras. Please, please Zeiss make a Loxia version for those of us who can't afford even a Leica M9.

I wonder how much viewfinder blockage will it have on the Ms.
The Zeiss 35/2 is already obstructing part of the lower right finder, and the 1.4 is even longer so to speak.
The MTF chart looks great though, even better than the 35/2.
I might get one if the real world performance is better than the 35 Lux

is there anywhere other than beyond lloyd's paywall to view these charts and assess how much damage the cover glass causes?

Not that I'm aware of. Since they are from Zeiss, perhaps they will show up somewhere freely accessible. Maybe Edward can get Zeiss to post them on FB!

For some reasons, Lloyd is the only one with the exclusive full set of MTF charts (WO to f/16) and the FC and blur off-set charts for this lens. He has the same deal (full set of MTF charts) with the Otus 55 and 135 APO, but not with the Otus 85 (strange).

What I can say is that you get the same result as Roger had shown before in his blog. You got a very slight pump in the center but huge drop of the tangential line. Zeiss gave him up to f/8 and even then, the performance on a Sony is still no where close to the native M.

Steve.

Unfortunately, with the release of the soon to be available FF Zeiss 35mm f2 Loxia, I doubt very much that Zeiss will release a 35mm f1.4 Loxia for the E-mount anytime soon. They have many many other FF Loxia lenses in the E-mount on their list to bring to market well before that.

Is there a situation where you get the same or better performance out of an adapted lens versus the same lens on its native mount? I don't believe so.

Adaptation is convenience. You have to be willing to sacrifice some performance, because you're going to. Whether or not you notice it is another story.

sure there is there are a few lenses that will perform better the a7r than on any canon camera.

there are even a few leica lenses that perform better on the a7r with a good adapter versus the m240, especially since there are helicoid adapters.

in any event, this lens will certainly have higher performance than my c/y 35/1.4 on the a7 for what i shoot with c/y 35/1.4 (not landscape). the question remains as to whether i will like it's look better, since raw performance is not my primary method of judging a lens.

Unfortunately in the case of Leica R lenses, Leica only offered the 10 mega pixel DMR for the R8 and R9. No other option has been available since then and the system is now out of production. For usage on a digital camera, R lenses need to adapted even on the Leica M240. However, with the new technology these lenses can prove higher performance for sharpness on the higher resolving new sensors of the newer available cameras such as the Sony A7/A7r, Nikon 800/800e/810, and the Leica M240.

I can actually be pretty patient. It is not as if I can afford the Loxia version right away anyways. In the meantime I will keep my ZE 35 f/1.4, when I am not bothered by a big lens and I will pick up either a Leica 35 lux pre-Asph if I want a really small alternative or a Voigtlander 35 f/1.2 if I can live with a fairly small option. Then if they make the Loxia in four or five year I will upgrade to it. Even given the disappointing news about the ZM on the Sony cameras I still might upgrade to the ZM if it is great for portraits and I suspect it might be. At 35mm I do shoot mostly portraits, but it would be a bummer that such a nice lens couldn't do longer shots well even if I didn't use it for that very often. I might supplement it with a Leica R 35 f/2.8, which is a very nice and under appreciated lens and would handle distance shooting very nicely.

so i did get a look at those mtfs. turns out the zm measures better than c/y even with the 2.5mm cover glass included out to 18mm at f/5.6, where the tan line might fall a little faster on the zm. obviously the sag line is higher throughout.

i suspect the lens will be perfectly useable for me, but it's possible the astigmatism will give a weird look i don't like.

Hmmmm, the 35/2 Biogon is already better than the Lux. Some might argue the bokeh is ugly, but with the Distagon, even this excuse is gone.

Looking at the MTF for the Loxia Biogon 35 again, it's tan line also takes a major dive after around 18mm out. hmm.

the c/y actually has a a midzone dip (still visible at f/11) that keeps that tan line well below the zm till then. actual corners on the c/y are pretty ok on my a7.
