首先必需感谢这forum里 的多位师兄帮忙,才让我有机会拥有这支名镜,在此多谢各位师兄们了!

The size of Otus 55/1.4 is rediculously huge, with a filter diameter of 77mm and a weight close to 1kg. It dwarfs the Rollei QBM 50/1.4 Planar, which is probably the smallest 50/1.4 Zeiss has made in the history with a filter size of only 49mm. But to me despite the weight and size, the lens is very comfortable to hold and use on a SONY Alpha 7R with vertical grip. But I have to admit the lens is heavy to carry around in the camera bag, but certainly not so when in use.

The lens optical formula is a Distagon wide angle design to allow more possibilities of optical corrections as compared to the well proven and copied Planar design which more or less has reached the limit of technical possibilities. Focusing throw is very large and smooth, which allows very accurate focusing at f1.4 coupled with full frame mirrorless focusing magnifier function. For this lens Zeiss has moved away from the conventional complete lens group focusing method and using internal focusing. The focusing grip is an adequate ring somewhere in the middle of the lens, and the rest of the lens are just not moving while focusing is done.

Optical perfrmance of the lens in real life is of very high resolution and very sharp, even at f1.4. And I would say the Otus 55/1.4 is designed to be used at f1.4. The centre sharpness at f1.4 is incredible, and the high resolution allows you to do very large magnification. I tested the lens hand held but with a minimum shutter speed of 1/125. And with the high resolution of the lens at 1/125 hand held I can comfortably take sharply focused photos with Alpha 7R focus magnifier. I remember is those film days where I first encountered the very fine grain Kodak Ektar 25, I do get pictures that were not sharp due to low shutter speed as a result of the high resolution of the negatives.

Depth of field is of course narrow at f1.4. But a half body portrait with the subject facing fairly direct to the camera both eyes can be adequately sharp like the shot below.

Alpha 7R, f1.4 1/125, ISO 500.

Was comparing the lens construction of ZM 85/2 Sonnar and Otus 85/1.4 Apo Planar, and felt that the Sonnar construction looks like a Planar and the Apo Planar construction looks like a Sonnar !?
