Сlose-distance resolution test, minimal distance
Testing methods description
- Target: 10-15 cm picture, printed on glossy photo paper
- Distance: 1.7m
- Camera: Sony A7II (24mpx, full-frame, tripod, remote control). M-mode, ISO fixed, WB fixed, SteadyShot – OFF.
- The test was repeated for every F-stop on every focus position with manual focus adjustment for each shot. That is to avoid the effect of field curvature.
- RAW processing: Capture One, default settings. All quality settings – 100%. Crops – 300×200 px

Yashica ML 50mm 1:1.9 – final conclusion
This lens may not be the fastest or the sharpest, but that’s okay, because – this is a rare case of a lens capable of swirly bokeh with very good sharpness. To clarify, the sharpness of this lens is quite common, it is somewhere in the middle of the ratings among all possible fifties, but for the swirly bokeh developer, this is a very good result.
So, dear fans to shoot something that is not in the focus area – you should at least try this lens. Of course, it is not very iron, not huge and not from Soviet Union (joke), but suddenly you will like it.
What about other traits – nothing special. The lens has a hard vignetting on wide opened aperture, it needs to be closed up to F4-5.6 for the correct distribution of sharpness over the frame. And it has noticeable geometric distortion, it looks strange, since, for example, on Minolta MD 50mm F2 (MD III), such distortions are generally invisible. I even think this lens looks a little overrated. Not much, but the prices for them are still slightly higher than for others with similar characteristics.
According to the test results, this lens can hardly be called universal. It is best suited for playing with bokeh, and for more ‘accurate’ photography, it is better to take something another.
