PROTON 2.7mm f/2.8 (s-mount) – عدسة لـ Proton CAM/FLEX/4K

Installed this on my Proton CAM for indoor real estate shots, and the 2.7mm focal length makes tight hallways look spacious without the fisheye warp. Sharpness holds up well even at f/2.8, just wish the focus ring had a bit more resistance.

This ultra-wide angle really shines in tight spaces; I was able to get the whole room into a single frame without that fisheye look. The aperture opens up enough for decent indoor shots even when lighting is a bit dim.

Was surprised how little barrel distortion there is for such a wide lens—the ultra-wide field of view opens up tight alley shots without that fish-eye warp. Clears up nicely for the cam sensor, too.
