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.
No question just praise! Thank you so much for the excellent product. It was as advertised and I can’t wait to get into film photography."
"Doing business with Robert was absolutely amazing. So helpful, pleasant to talk to, definitely went above and beyond. I was looking to get into film photography and Robert gave me a bunch of options and suggestions, plus tons of tips and things to read up on. I would recommend his services to anyone!"
