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.

Minolta MC Rokkor-X PF 50mm f1.7
I have several copies of this lens for matching with Minolta bodies. It was Minolta's standard kit lens. It is made well, just like most other Rokkors. Focus dampening is perfectly balanced. Aperture clicks at half stops from f2.8 through f16. This lens balances very well on my Eos M3. Focusing is quite easy through the finder. All sample shots are handheld.
At f1.7 it is sharp as long as you don't shoot at minimum distance. Once you back up a foot it tightens up nicely. At f2.8 & up it is tack sharp at all distances.
Contrast is excellent through the entire range.
Bright backlight will cause some color shifting and bokeh fringing at certain angles. Purple fringing is well controlled though.
Color renditiion leans toward the warm side.
Bokeh has a natural feel at wide apertures. Bokeh fringing is present at f1.7 but gone by f4.
This lens regularly sells for less than $50 and that makes it a great value. Just don't expect it to be as good as a 58mm f1.4.
