I have a Celestron 300/5.6 mirror, and its a very nice lens. Very small and
light. I don't think its as sharp as the 300/4.5 Zuiko, and you only have
f5.6 aperture, but its about 1/2 the size of a can of soda, actually about
the same size of my 100/2.0 Zuiko, and lighter. Very easily hand held at
1/250 or above.

I used ISO100 and ISO200 speed film on a sunny day at the motorcycle races I
was almost always at or above those speeds. However, as I was back from the
track 300mm was only good for about 1/3 frame for motorcycle and rider. It
worked very well at Sears Point where I found places to be about 50-75 feet
off the track, but a Laguna Seca I was typically about 100 feet off the
track to avoid fences in the view and the images aren't as big as I want.
Next time I'm trying my 600 with a monopod. For what these 300 mirrors cost
(~$150 or so on e*ay) I think it was a good lens to buy.
