Is the zeiss loxia 50mm f 2 sharp wide open?

The lens page for the Zeiss Loxia 50mm f/2 covers the basics: it's a manual-focus prime for full frame, it mounts on Sony E, and it isn't stabilised. It doesn't say anything about how sharp it is at f/2, so I won't guess.

What I can tell you is what f/2 does for you. It gives a shallow depth of field, so your focus has to be spot on. The lenses guide explains how the f-number affects light and background blur. If you're shooting portraits, the portraits guide shows how to get the most out of a wide aperture.

For a real sharpness verdict, look for hands-on tests from people who have used this lens, and check the image corners and edges as well as the centre.
