Pentax SMC Takumar 55mm f1.8
SMC Takumars are legendary for good reason. They are sharp, have great color rendition, excellent shadow detail and a nice balance of contrast. The 55 1.8 Super Multi Coated Takumar is a great example of this legend. Bokeh is silky smooth, optics are tack sharp and colors are beautifully rendered. Chromatic aberrations are very low. Bokeh is smooth. This lens is very close in performance to my Contax Planar 50mm f1.7.
