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.

Auto Tamron 35mm f2.8 (Adaptamatic)
This is a rare lens. Adaptamtics predate Adaptall lenses. The adaptamatic mounts are a bit finicky and more scarce than the lenses. I've discovered that my Eos M adapter doesn't allow infinity focus with this lens so I will be updating this page after I test with my 6D.
I have learned that this lens is tack sharp wide open and it handles flare very well. There is some minor fringing in highlights but it is barely noticeable. I can't wait to take some 'important' shots with it. Bokeh fringing is very well controlled.
