Mir 37 1B (37mm f2.8)

In preliminary testing I found the Mir 1B to be sharp, especially from f4, with low distortion, excellent color rendition and nice shadow detail. The lens is prone to flare; use a lens hood. Chromatic aberration was minimal. Focusing is smooth and precise. The aperture is almost circular and stepless, which is a nice feature when shooting video.

Quantaray 500mm f8 Mirror

Most Quantaray lenses were made by Sigma and some were made by Tamron and Tokina. This lens performs like a Sigma Mirror lens. It is reasonably sharp if you can hold it steady. It has the typical ringed bokeh we see from mirror lenses. Contrast is surprisingly high. While it is not a Zeiss or even a Tamron in quality, it is still far better than any of the off-brands flooding the market.
