Kamlan has just launched the second version of its 50mm F1.1 lens for cameras with APS-C sensors, and we've been able to shoot with a sample copy to get an idea of how it performs.
Designed with Fujifilm, Sony, Micro Four Thirds and EOS M mounts in mind, this all-metal lens is all-manual and offers plenty of background blur when you want it, at an equivalent focal length of 75mm on the Sony a6500 we tested it on.

These small, fast primes aren't cheap, but neither are the cameras you're meant to mount them to.
Shiftcam's Pro line lenses attach to smartphones via dedicated cases or a universal lens mount.
The pop-up design allows for image and video recording in both folded and unfolded state.
