Yellow

Got this new lens, well very old one from 1970's vintage.  It's a Tamron 105mm F2.5 (CT-105).  I bought it to see if I like it more than my copy of a Nikkor 85mm F2.

This Tamron has very nice bokeh (out of focus area) and greet metal built like tank construction. Very smooth in operation with high precision manufacturing quality.

Well, I personally like 85mm more in several reasons. So, I'm going to sell this Tamron but I bet I might be regret as it is much better for portrait work.
