I think it's a great shot! You were very lucky to get those exact circumstances too Thomas! :D

Is the odd looking bokeh a characteristic of all mirror lenses?

Unfortunately the answer is Yes. Have a look about halfway dow Bob Atkins essay Bokeh and Background Blur where the effect is described and illustrated with this image (both shots at 500mm and f/8):

That's unfortunate. I guess you can't have everything you want in a lens. Can't beat them for price though.

The doughnut-shaped bokeh is one thing, which under certain circumstances is not too distracting. But what I find more of a nuisance is the MF: With a limited dof that matches a 500mm F/5.6 (!) the lens is unforgiving when you don't focus right. I now tend to shoot a burst of 3-5 shots while focussing, doing "focus bracketing" in effect and hoping that one of the shots nails the correct focus.

Great picture!
Suggestions
1. Cut out the guy on the left... he's sharp and taking away attention from our main subject
2. You a ps-man? Suppose you are: make it al B&W except the child and give him a little more contrast en take some of the brightness away...

And never say it was a lucky shot!!! Your a pro no matter what others may tell you!!! Never ever admit it wasn't intentional :)
