I'd really like to have one of these.

I'm not sure what you mean by "200m 2.0 prime (out of produciton)". As far as I know, the Canon EF 200mm f/2L IS USM is still in stock at many major retailers like B&H. Did you mean the older 200mm f/1.8?
It's still on Canon's web site.
Here is the link http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=153&am p;modelid=16357.

Guys, I think you're missing something important. He said "200m 2.0 prime", which is 1000 times longer than a 200mm prime. I bet there is only one like it in the world. Tough to handhold, that. I'd really like one, too, but honestly, I don't think it'd fit in my house. Actually, not even my driveway, come to think of it.

According tho these guys, the longest lens ever made for a camera is a 5200mm f/14. If you count telescopes, the longest is under 20 meters.
So much for the 200m f/2 prime.
If you cheat by stacking a bunch of barlows, the twin Keck telescopes will get you to 200 meters at f/20 (i.e. 200000mm f/20). Normally it's a paltry 17500mm f/1.75. []
