Wanted to buy: 200m 2.0 prime (out of produciton)

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.

Sorry for rambling, but this got me wondering, and google led me to this discussion of the longest focal length lenses ever made.


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. [:D]

Sorry group
What I meant was a 200mm f 1.8

Well, if it's a 200mm f/1.8 you want, Bryan says where he got his in his review:

Lee at chamcamera proved reliable and seems to at this time have a deep source for these discontinued lenses.

You might check there. But I still think you should look into a 200 meter f/2. [:)]

For the sake of asking, why would you want one? They're front-heavy, not so sharp in the corners, and non-repairable. Oh, and on the rare/common occasion that you could benefit from IS, it's not there.

I can't speak for iND, but one reason that I want it is bokeh. The 200mm f/1.8 is soft because it has intentionally undercorrected spherical aberration, which greatly enhances bokeh at the cost of some sharpness, similar to the 50mm f/1.2.
