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 only had time for a few shots before this lens was sold off. Bushnell has specialized in sports optics for 70 years. For a short time they distributed camera lenses that were made in Japan. Like most 70's lenses, they were well made. I got my hands on a Nikon Non Ai version of the 35mm f2.8. Sharpness is good from f4 up. Contrast is average and color rendition is warm. I did notice some minor fringing up to f5.6. At f5.6 sharpness is very good. Close focus performance is good. Focus dampening is excellent. Distortion is negligible. If you need a budget 35mm, this will do fine.
Bokeh fringing is noticeable, but color shifts are not severe and fringing is corrected as the lens is stopped down.
