Yashica ML 50mm 1:1.4 vs Yashica ML 50mm 1:1.9 – comparison – final conclusion
No surprises – faster lens is able to provide a better result if aperture a bit closed, but Yashica 50/1.9 still the perfect lens with a great resolution. The difference for real photography in sharpness terms doesn’t matter.
