Has anyone had the chance to try these out. I am curious to hear how good they perform for as image quality and field sharpness. I appreciate any input.

I just received a 20mm a few days ago. In a nutshell you get what you pay for. Reasonable center sharpness but pretty severe seagulls at the outer 30~40% of the fov. The afov is at least what is advertised, almost identical to the Panoptics. If you really need the edge to be sharp then don't consider them.
