5 Pentax 50mm Lenses Tested; The Ultimate Pentax 50mm Lens Comparison Review.

Pentax K SMC 50mm f1.2 vs. Pentax K 50mm f1.4 vs. Pentax-M 50mm f2 vs. Super-Takumar 50mm f1.4 vs. Super-Takumar 55mm f1.8 (same optical scheme as K 50mm f1.7.)
CORRECTION AT 17:54: The Super-Takumar 50mm f1.4 has a single coating. I incorrectly state in the video that it is uncoated.
Extensive testing on Sony a7ii and a7s cameras for bokeh, maximum bokeh, fine contrast, color rendering, night, low light, and sharpness tests at different apertures.
