p.1 #1 · p.1 #1 · Sony FE to Nikon Z Electronic adapter from China


I don't know the details,such as AF speed and accuracy,when will it go on sale....etc

I'm just looking forward to My Loxia35's performance on the 1.1mm thickness sensor cover glass of Nikon Z.

L 35 may well perform worse on 1,1mm. It has been optimised for Sony cover glass as well as they can without major redesign. It would be surprising if was better optimised for 1.1. Of course ZM 2/35 on no coverglass performs slightly better, but if I had to guess ZM 2/35 on 1,1 would perform no better than Loxia on Sony.

Great news!

AFAIK, the sensor stack on the Z is 1.6mm (vs 2.5mm of FE). Also, AFAIK, none of the lenses availabel in FE mount are diffraction limited at their wide open aperture.

So, the chances of Lox 35/2 doing better on a Z are good.

It is precisely because there is no redesign, so Loxia35(Exactly is Biogon) still can not be 100% suitable for Sony's cover glass.

Maybe better, maybe worse, who knows? That's the most interesting thing.

Bastian at Phillip Reeve's web site has in his review of the Loxia 35/2 compared the ZM Biogon 35/2 to the Loxia Biogon 35/2 FE on the stock Sony sensor, https://phillipreeve.net/blog/review-zeiss-loxia-35mm-2-0/ . Scroll down a bit and you will see the comparison. The difference in performance between the two versions is so great, that we can't tell in advance, if the ZM 35/2 or the Loxia 35/2 is the better lens on a Nikon Z6/Z7.

I am a Loyal readers of Phillip Reeve

I once owned ZM35/2,It is design for film in 2003, ZM just perform very poor on 2.5mm cover glass, ZM35/2+Film(0mm) better than Loxia35+Sony(2.5mm), ZM‘s optics performance(Field curvature and Astigmatism) better than Loxia35,the difference of MTF can also be reflected.

The so-called optimization of Loxia35 is more like ZM35/2 with poor quality control(the distance between the lenses and the distance from the last lens to the sensor)

Zeiss can't optimize Biogon better on 2.5mm sensor cover glass,Loxia35 can't achieve the same optical performance as ZM

I just want to know about Zeiss's optimization of loxia35,would it be better on 1.1 mm sensor cover glass?

Sorry to rain on everyone’s parade, but I had an A7RII modified that had a 1.8mm total sensor stack and the L35 was SIGNIFICANTLY worse vs a stock Sony. I’ll see if I can find samples but it will degrade on a Z camera, as will likely all the Sony wide primes.

L35 is not exactly the ZM Biogon, small aspects of the surface shapes and possibly spacings have been altered for the Sony sensor, so it has much less FC on Sony than ZM (though l35 performs a touch worse on Sony than ZM on film, judging from published MTF, as correction while great is not perfect.) Of course it shares the same rough block diagram, but that is a crude similarity.

Also, unrelated to the Loxia: I love Techart’s innovation, but I wouldn’t spend more money on them as a brand. They need to get bought be a real company that understands product life cycles and continue to support their products. They abandoned the TA-GA3, which could be pretty awesome with a FW update. The LM-EA7 got firmware, but distribution seems to have disappeared and who knows how it’ll play with the new AF firmware. Then there’s the wobble... Seems to me they get the sale then move onto the next big thing, leaving buyers SOL.

Seeing how many iterations there were of both Metabones and Sigma's EF to FE adapters I would be rather hesitant in this case as well. Realizing such an adapter well requires more resources than Techart seems to have. I guess we will see more adapters in the future.

What about moisture resistance, dust, etc?

What would people gain with such an adapter if already owing an A7riii? Buy an additional Nikon Z, what for?

I am curious, where do you get the number 1.1mm?

I saw the number reported by Kolari who do sensor stack modifications for the Sony A7 series cameras.

I think the reason to buy and Nikon Z is if you decided to move away from Sony but wanted to still use some E mount glass. The Nikon Z system is interesting to me for some of the glass that will perform better on it than a Sony. For example, I really like the Nikon 300 f/4 PF and the 500 f/5.6 PF and they are much more easily adapted to Nikon Z and will like perform better on it than with the Commlite adapter on the Sony E mount. For me I also would like that my Milvus lenses in F mount would be adapted with full EXIF. I would hate to leave some Sony E mount lenses behind, however. I think that is reason to hope that a Loxia 85 f/2.4 would work pretty well on the Nikon Z and that is one of my favorite lenses. I would also love it if the Loxia 21, 25, and Voigtlander 40 f/1.2 worked well, but I am less sure they won't see a performance degradation.

For me it is an interesting question whether the Nikon Z sensor stack performs better with Leica M mount lenses or Sony E mount lenses. Consider a couple of examples: how does the Leica M 21 f/3.4 Asph work? How about the Lox 21 f/2.8? The Voigtlander 21 f/3.4? Do they all work pretty well? If they do you get more choice with the Nikon. Do none of them work very well? Then the Nikon's sensor stack is in a no-man's anti-goldilocks zone which makes the camera pretty undesirable to me. My guess is that it is somewhere between these extremes and I am very interested in just where it lands. I am not surprised there is an adapter that let's it mount at least some E mount lenses, but the big question isn't answered yet: how do those lenses perform on that camera? Depending on the answer to that question there either could be a compelling reason for me to get this camera and move away from Sony or not reason at all.

So according to Lloyd Chambers the actual sensor stack thickness of the Z7 is 2.3mm.

Is it result at INF?

Yes, if you include the glass epoxied onto the sensor chip. Some consider this part of the sensor stack some do not.

It's definitely interesting but the Z7's thinner filter stack may not improve performance for this lens. Do you love the Loxia 35/2 that much to go through the trouble of adapting it on your Nikon?
