Lovely lens! It reminds me of the one lens I use, very similar to yours, a Super Carenar MC f=135mm 1:2.8.
Made in Japan:
I believe it was one of the cheaper lenses at the time, sold as kit lens for many cameras. Anyway it may be luck, but this one packs quite a punch when it comes to picture quality. I really treasure this one above my other lenses (although I do have a certain affinity to my Sigma Art 50mm).
It's a lean mean bokeh machine. :) And even comes with a built-in lens shade:
I'll post some portraits and stuff later on my own blog.
I love the first photo, the processing you used makes it look vintage too.
Happy shooting with that absolute lens-gem of yours!
oooo ) Sigma Art 50mm, you want to test it too. Waiting for photos on your blog
Sigma? It is sharp:
Also, all the pictures of the Super Carenar lens were taken with the Sigma.
I might post a blog about my lenses, yes. :) Consider it on my To-Do list.
publish of course, it would be interesting to take a look)
