After years of using auto focus lens, this took some rethinking. After making that adjustment, the results are very rewarding. This lens is small, but very solid. If used properly, there is very little wide angle distortion. The sharpness and contrast are it's other great virtues.

Fantastic performance in a small package. My only complaint is the tactile issue of focus and aperture. It's hard to go from one to the other with the camera at eye level, as both the control rings are relatively smooth and the same diameter. I also use manual focus Zeiss Contax lenses.

You can find a lot of reviews about this lens and they all says true. Small beast that renders beautiful sharp images. Yes it expensive but it worths money.

This is a great lens for landscape and cityscape photography. It's form factor is very compact and fits small camera bags with Sony A7 series cameras. I was nervous about the manual focus but the Sony system makes this SO easy.

I have to confess a hopeless addiction to the Zeiss Loxia line. This is my third (and last!) after the 35 and 50. All are astonishing! I evaluate a lens by real world performance in making images, not by pixel peeping.

Ultra sharp, lightweight and delivers Zeiss quality.

This is my first Zeiss lens, not the first prime. I had to make a decision between Batis 18mm vs Loxia 21mm and that wasn't an easy decision to make. I tried both lenses; both performed equally well but the Loxia edged slightly ahead.

Excellent image quality. Super sharp. I purchased this lens specifically for landscapes in the Canadian Rockies. I prefer a larger perspective than a 21mm lens provides. Accordingly, I did not use this lens much. If I ever really do need a 21mm lens, this is the go to lens.
