If you attach the new Venus Optics Laowa 9mm f2. 8 Compact Dreamer to a Sony a6500 camera, then you'll see that while it's a weird lens it's a lens that Sony really needs for their system besides a fisheye.
It's billed as a lens with really low distortion--and it indeed doesn't have a whole lot of it except around the corners. Designed for APS-C sensors, I also feel like this lens isn't necessarily a big winner for Venus Optics. Many of their lenses have this beautiful character to them. But this one feels flat in many ways--and that means that you're going to surely rely more on what the sensor is capable of doing. That's fine, but I've never been so lukewarm about a lens from Venus Optics. . thephoblographer.com
