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.

Eos T2i - APS-C

Enlarging lenses make great macro lenses. They are flat field lenses with excellent corner sharpness, good shadow detail and are usually tack sharp wide open. They are also small and light, which makes them easy to handle on mirrorless bodies.
Not all lenses are created equal. Some cheap enlarger lenses are simply not very good. This lens is reasonably inexpensive and it performs quite well.
It is tack sharp from f3.5 thru f11. At f16 it suffers from diffraction. Corner sharpness is superb.
Contrast is slightly soft at f3.5 but excellent at f5.6.
Color rendition is excellent.
Bokeh is very soft wide open and it remains uncluttered as the lens is stopped down. There is some bokeh fringing at f3.5.
