Since two months I own the Walimex Pro 135mm F2.0 and hadn't the chance to perform a menaningful test in the night sky. Few days ago there was at least a "half-opportunity".
Frames were taken at F=2 with my unmodified Nikon D5200, under strong backlight due to the moon, not the best clarity, without any guiding, and the ordered focussing aid not yet arrived.
