Under heavy wind and rain, I can't even open my eyes during shooting. I have more need process, this one is after I pack my stuff and run, then look back, I decide give it another click, hand hold, focus scale focus, f1.4, 1/125, ISO280 with two more stop push. It was really pretty dark already.

To all Zeiss OTUS owner, do you lens spot on infinity mark on you Canikon body? Mine seems not,(about 3mm before the mark) usually, I will not worry about this,(if it is within +/-1mm range) but seems remember before it was on and my 135AO is spot on the mark.

Lowell, thanks for your reply. This is a only concern to me because of floating element design. and Flange distance calibration was listed for any lens CLA from either Zeiss or Leica. After seen performance degradation for my 50lux ASPH on A7R compare to M9, this concerns me. Since I also have D700 at hand, I verified that it is consistent in both case, looks like Nikon have great tolerance but I can't say the same thing with Zeiss.(135APO is flawless though)
Luckily, This OTUS's infinity test pass my critical QA Nowdays, with high density sensor and really high performance lens with different cover glass, the lens performance and system behavior really hit my nerve. Used to be never an issue, now become a problem. Generally, I don't pix PP, but to efficiently use system and achieve really high IQ standard the system designed for in field require you spend some time to understand the system.
The Rokinion 14mm with F mount perform very differently between A7R and D810. FC characteristics change quite a bit. and I can never have it perform as good as on D810. I don't even bother trying to figure out where the problem stem from. Use OEM lens for performance the gear designed for is the only recommendation I have, especially WA or SWA. Life is too short to spend on debugg system.
2 hours, the bird didn't move at all until heavy wind and rain at the time of leaving. All images took that day have it

Interesting insight Michael. I may be in the process of obtaining one and if I do I will have to tighten up my QA process for such a demanding piece.
I miss focused handhold shot though by assume infinity mark works. Another reason you want know your gear. Under that condition, focusing by LV is out of question.
Here is one with 5 OTUS vertical images stitched, 110M file
This is why I feel that Otus and A7RII are a fantastic combination for achieving perfect focus. Otus and its remarkable focusing ring, with perfect throw and super-smooth rotation, and A7RII with EVF, peaking and magnification for every shot. It should be called Otus-Focus, like a magical formula.
Agreed - it's terrific. I haven't had the 55 Otus very long yet, but my impression is that this character works as well as it does with the 85. The "almost an Otus" 135/2 also has this same quality IMO.

Philipp, you know what, I hate its ultra smooth focusing ring. It is very difficult to fine control focusing for catching my kids also make it difficult in field that you don't want accidentally bump anything that can change focusing. I double check my focusing for every shot I made if I have time because of that.
Leica R is great in that regards.I remember planar ZF.2 85mm also have wonderful focusing feel. Planar 50 is decent as well. but 100mp, 135APO, OTUS 55 and 85 are all too smooth/loose to my taste.
Having said that, this lens have wonderful rendering for my family portraits as well to my eyes, calling perfection. (very upscale rendering, different than R)
I mess up with my shooting that day, otherwise focusing by scale is perfect in this case. Under that rain, you want minimize the gear exposed to the weather, you don't want use EVF to focusing as well.
As for OTUS with Alpha, I feel hold and focusing with 55OTUS at the same time holding A7R without stress mount challenge. but that could be just me.
Michael, I am not going to argue against focusing with the ZE/ZF series. I had almost all of them, and many served me well. But I have to say, in terms of sheer focus accuracy (and that alone) I find Otus more precise, for the reasons I mentioned above. But this works only if I have enough time that I don't need to rush things. Otherwise, in a pinch, a ZE/ZF is probably a better bet. So your comment when trying to catch your kids doesn't surprise me. I wouldn't even attempt what you have trouble with...:-)
I love the smooth motion feel of my Otus 55 focus ring. It is not as easy to accidently bump as my Ride 180/2.8 APO.
That R lens has very easy to move focus ring so that it can be used for fast focusing on subjects in motion.
I have no problems focusing the Otus 55 using LV on D800E or 5DsR when I have time to use LV. Even focusing using just OVF is not bad in good light, but definitely have higher accuracy rate with LV. The IQ when paired with high MP sensor is incredible.
Every R lens I habdle have slightly different feel but none of them as smooth as Zeiss OTUS, it is not really bother me per say, but I prefer a little more damp here.
