500mm Mirror

I got a Pentax M42 adapter earlier with some other stuff in a package from Ebay. To my surprise, my old 500mm mirror lens for Canon is actually a M42+Canon EOS adapter. So it is nice and easy 500mm mirror for K10D. I took a little walk around with it, mostly aimed for squirrels. It is difficult. 500mm needs a fast shutter speed, even with SR and ISO 800. This is hard to get even 1/150s in shade. And this lens only have F8 and it is soft. The bokeh is interesting for mirror lens. Usually people hate it. But sometimes it looks interesting.
