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.

I took a walk around the porch w/ the Rokkor PF 58mm f1.4. On the M3 body it handles well.
Focusing with the optional viewfinder is reasonably easy.
As you can see below the lens is sharp wide open. It is sharp in the corners as well. The shot of the tree was taken thru dirty glass and the corner is still sharp. Bokeh is smooth. Bokeh fringing is minor and CA is insignificant. I did not test for flare. I'm not a fan of shooting into the sun. Contrast is excellent and color rendition is very accurate.
