Is this the SL series lens (a small stylish red "SL" mark)? I had one of these and found it was pretty good when stopped down but a little soft wide-open. It had a pretty decent built-in hood. I ended up selling it when I found a FA*400mm f/5.6 secondhand at B&H. AF was pretty tempting at 400mm. The Pentax appears to be a bit better optically, but was not quite as good as I expected.
