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 M3 - APS-C
Another budget lens but it is a 135mm and most 135mm's are quite usable. This one is also quite usable.
It is soft at f2.8 but tightens up nicely by f5.6.
Color rendition is a bit on the cool side. Contrast is a bit low.
Purple fringing is noticeable at wide apertures but should correct easily in post processing.
