Carl Zeiss Otus 1.4/55 ZE

This lens was used for the first time in the Lithuania shoot. Of course, it was checked in advance.
Overall, this is a high performance lens, but it has really poor vignetting around the released area, and not only the surrounding areas but the whole image is produced 1-stop too low.
Further, the manual focus combines with recent single lens reflex focus screen creation leading to a much higher degree of difficulty when using it.
In the end, we gave up using EOS, and took α7R with built-in electronic view finder.
What is really good about this lens is its resolution around the focusing and the beauty of its blurring.
In particular, the blurring slopes gently from the focused area giving a sense of volume. So wherever it is taken from, when blurred it will not produce the same picture. It can be quite interesting when this is used to produce a deliberate result. The image also has a sensual quality.
