Sigma 28mm f/1.4 DG HSM Art 鏡頭 L接環用

Picked this up to pair with my S5 and the chromatic aberration correction is noticeably better than my older adapted lenses, especially in high-contrast corners. It focuses quickly in dim light which is a big plus for me.

The coma flare correction is a godsend for astro shots—stars stay pin-sharp right into the corners. Wide open at f/1.4 it's got that classic Art lens bite, and chromatic aberration is basically a non-issue.

I’ve been testing this lens for landscape work, and the correction on sagittal coma flare is immediately noticeable—stars and streetlights stay sharp corner to corner. Focus is snappy on my L-mount body, and the f/1.4 aperture gives a dreamy separation that really elevates foreground detail.
