Jupiter 37A 135mm f3.5

This Russian lens comes in M42 mount. It produce sharp images with smooth bokeh. On the rear glass it has a lot of tiny bubbles, it looks like airstone for the aquarium. The lens doesn't have "MC" words, so I assume it isn't the multi coated version, but strangely you can see some color on the front glass.

SMC Pentax 35mm f3.5

Bought this lens from ebay. It's very light lens, but it produce super sharp images with nice color, but the bokeh's not that smooth. 35mm on 1.5x cropped sensor becomes 50mm, and it's more convenient with human eyes' field of view.
