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.

Vintage Lens Reviews
Hover above the brand boxes below to choose a lens review. My reviews are simple and to the point. My sample pics are usually of mundane subjects and often taken in less than ideal lighting. I have limited mobility so I shoot what I see and have access to. I believe that mundane subjects give a better representation of a lens' characteristics. Also, by shooting the same subjects repeatedly, I am better able to compare performance between lenses.
Most of the sample pics have been taken with an Eos T2i and an Eos M3, but I am currently doing tests with an Eos 6D.

Studio Tests
In this set of tests I will be looking at image quality in a basic studio setting. These shots will be taken with two strobes; Each will have an umbrella. The background will be natural so that the lens' bokeh can be appreciated. There are several benefits to doing these tests. I don't have to leave the house. Studio lighting allows me to shoot at low ISO and small apertures. If a lens suffers from diffraction at f11 we will be able to see it. I can shoot w/out worrying about camera shake. White balancing is consistent. Bokeh fringe testing will be very accurate. I finally have a use for all the knick-knacks we have laying around the house.
