I recently picked up this fun screw mount lens for a sweet deal (25.00) on Craigslist. I've never owned such fabled optics, and honestly, never really cared about them so much. I have had some fun over the past years with old lenses adapted for the Canon EOS system though, and have shot through old Asahi's, Vivitars, Sonnagars and others, but honestly, this one is the sharpest.
As macro as this Tessar gets, full frame
It glows on the highlights however, as you can see in the videos second shot, it gets a little dreamy around the highlights, unlike the EF 50 1.4, which is my go to for most things, and is to be expected. 50 years of glass and coating development separates the two.
