I like how they describe it as a cannon. It's not, although for those used to the prosumer market it seems like it. They should see a 600mm, or even one of those rare 1200mm lenses =D
I'd be curious to see what a modern-day EF 1200mm f/5.6 L IS II lens looked like, and what kind of IQ it provided. I suspect it might barely border on "hand holdable" (i.e. like the old 600mm f/4 L) if it used todays fluorite elements and titanium/magalloy body. The 600mm f/4 L IS II with a 2x TC still offers STUNNING IQ. I can't imagine what a native 1200mm lens comparable to Canon's current-day IQ would be like. And, you'ed get 1680mm out of it with a 1.4x TC!
If they can ever get those diffractive optics to start delivering, you might actually be able carry it. Hopefully with some 6 or 8 stop IS. At 1200mm you'll need it!
Good idea. But wouldn't a modern 1200mm lens cost over $20k, given Canon's cost structure for superteles? Maybe not, since it's a little more limited in its usefulness due to the narrow field of view...not many sports pros would use it.
I believe the old 1200 lens sold for over $100,000.00.
Which makes a $20k price tag, especially for a hand-holdable 1200mm DO, rather appealing!
True, but only if you're willing to spring for $20,000 for the lens. I doubt you would. I know the older 1200mm sold for a lot, or rather does sell for a lot on the used market...as do other exotic lenses. I wouldn't pay a dime for it, though. Too heavy, no stabilization, not all that sharp other than in the center.
You doubt I would? Hmm...I just dropped $11,000 on the EF 600mm f/4 L IS II. A purchase I am quite happy with, and one I think was WELL worth the money. BTW, if you need proof of that:http://jonrista.com/2013/06/28/the-arrival-unpacking-and-glamour-shots/
I also plan to order a 2x TC III to go with it, which would make it a 1200mm lens when attached to a 5D III. If someone made a 1200mm DO IS with a light weight barrel for $20k, I'd be more than willing (hell, partical dispersion diffractive optics would be even better than fluorite...allowing an extremely short lens design, if Canon can ever figure it out). I'd be rather ecstatic if it was truly hand-holdable as well. I hand-hold the 600mm+1.4x, and it is hand-holdable, but not particularly ideal (too long, really.)
