I picked up a Pentax Super-Takumar 135mm f/3.5 lens on eBay. I typically do not shoot much telephoto stuff. However, since this lens arrived, I have yet to remove it from my camera. Great colors and quality straight out of the camera. I haven't had to color correct anything so far. It is a fully manual focusing lens, which can take some getting used to. But, if you can nail-down the focus, you will receive very sharp images. Also, depth of field and bokeh nothing but top-notch. This is a great lens and can be found for a very good price.
