Oldie but goodie: UV Topcor 1:4 f=100mm Tokyo Kogaku

  Cost: $29 (market price $40 or more)

   

As a reminder, the UV mount lenses from Tokyo Kogaku were produced from the 1960's for Topcon's "cheap" line of camera's and do not have an aperture setting ring, as this is found on the camera body.

So, as I had both good an bad experiences with the Topcor lenses, I'm glad to state that once again, I was impressed. This lens was sharp, and did not display to many "old lens design" issues. In contrast the pictures show rich colors (probably thanks to the UV coating), and a crispiness that provides a true 3D feeling. The pictures feel like they have real depth. As bonus, a nice round bokeh effect, and ability to focus close to the subject. 

And it also follows the design and look of the other lenses in the series, so again a beautiful classic look. Also easy to use with smooth manual focus. For a 100mm, this lens is very small, almost the size of an older nifty fifty.

Yes, a keeper and part of my almost complete UV Topcor collection.
