Mine's Bigger Than Yours

Looking through my photos from the 2008 Farnborough Air Show, I remembered that I'd looked around during one of the flight displays and snapped this picture, but never put it online. 

I will leave it to my fellow photo-nerds to play Spot the Lens.

I've got a 500 mirror lens, it's rarely useful - colours are muted and it's always a little fuzzy.

No, what I meant was that there there are various optical tricks which can reduce the real length, as opposed to the focal length, but it adds complexity to the optics. That one looks pretty close to a true 500mm.
