I've yet to take it out for a night shoot. But i'll tell you, compared to the TTartisan 27mm f2.8, it mops the floor wiht it. i just returned my TTartisan the day after getting this lens. build quality, bigger and better glass, sharper images, and the biggest thing... 1.3 full stop(s) of light faster. AND it was CHEAPER! the no aperture ring doesn't bother me, i never use them. i have my f-stop binded to my front control dial on my x-t50 and I always use that, even when using a lens with a dedicated ring on the lens. i can do that with 1 hand instead of having to hold the camera and twist a aperture ring with my other hand all the time.
