Thanks Fred busy looking as i type.

Further though on my other question, any connection issues between body iv and lens causing it to black out?

Thanks Fred! Everything I see makes me think so.

Congrats Tim! I think you will love this lens.

Second I remember Samuli complaining about small barrel sizes causing ugly bokeh in the corners in Zeiss 'classic' lenses - considering the diminutive size of the Loxia I expect it here too.


That's not as simple as "small barrel size" though. It's barrel size relative to diaphram size and related to position of entrance pupil, as I understand it. The cat's eye is pretty bad on the huge Milvus 50/1.4 and even worse on the even huger Otus 55, for example.

Hi everyone, I just got my Loxia 21 and noticed that the "hard stop" at infinity is actually just slightly past infinity. Infinity focus is just a touch before the ring stops. Is this normal or is anyone else having this issue? I'm thinking about exchanging it except I'll have to go back on a waitlist. One of the reasons I liked this lens was true hard stop infinity so I could set it in pitch black and not think about it. Thanks!

Nope stop it is very normal. It's designed that way like many lenses . Reason being in warm climates you get heat thermals from ground and air and this affects focus. No worries you lens is fine

Thanks, Guy! That makes a lot of sense. I'm pretty new to the world of manual focus lenses.

No problem focusing needs to expand in heat so designers leave room after the infinity mark. Usually happens with long glass because the heat gets condensed. But no your in great shape. I just bought one today myself get it next week.

Funny, every Leica lens I own has a stop and it seems to be spot on from 10 below to 90F: with the Leica bodies.

Having to focus at infinity is a PITA for me with the A7.

The issue you are talking about is moot at 21mm-check me here, but I don't know of any UWAs which purposefully go past infinity. Certainly no Leica or Zeiss UWA lenses do in M mount, and their performance is a benchmark. My big Nikkors the 500/4 and 300/2.8 do go past infinity for the reason you mention but they have an adjustable focus stop which you can set for infinity.

If the Loxia infinity stop really is past infinity, it's pretty weak of them, at least for my way of shooting, no offense.

^^ Agreed on the hard stop for inifinity. It is much easier for casual shooting to have the hard stop set exactly at inifinty.
I have a CV 90/3.5 LTM that I use together with a custom ground adapter so it hit infinity exactly at the hard stop. I have used it for several years with a Nex6 and now with A7 and it works great in cold or warm temps.

A nice touch for Loxia would have been to have a user adjustable hard stop so you can set to your preference.

yup, it's not really a "feature". only longer telephotos need to worry about temperature change effecting the infinity stop. my guess is that zeiss just knows that the mount tolerances on modern cameras don't allow for a real infinity stop (i've heard the same complaints about their offerings for canikon). should probably blame AF for allowing camera makers to skimp on those tolerances.

The infinity stop is ever so slightly back and really once you know that I have found it not to be a problem

As I have aaid before, I have shimmed my adapters to give correct hard infinity stops with all the leica and voigtlander lenses I use on the A7, and also the few short focal length F mount lenses I use.
They have all worked fine on film cameras for decades, and now have worked fine on the A7 for a year, I can't see any reason for the Loxia 21 not to have a proper hard stop, my 21 Elmarit asph works fine like that.
Either its sloppy manufacture or what has been suggested is that the Sony bodies are not that consistent in register.

My ZE 15 and ZE 21 didn't have hard stop infinity either, so it's not just a Sony thing. (Or my 5D II had inconsistent registration distance.)

Does anyone know how the LA-EA adapters work with the A mount lenses? Do they have accurate hard infinity stops? Or is that asking too much of af lenses anyway.

Adorama tells me mine is still on backorder. I only ordered it on 4 January, though.

Strange... all my ZE lenses had hard stops. Same with the Nikon mount versions.

completely accurate ones? i've heard lots of canon people say that theirs focused a tiny bit past infinity. could be cameras like your were the reason for that...

Got mine Friday Jordan...I think you'll like it. I still can't believe has small it is compared to my ZE.
