I know this lens has been beaten to death on every forum on earth, but B&H just posted this new page with more information about this amazing piece of glass...
holy crap, lol, I like the pictures they show from it.
"For what it's worth, if you couple this lens to a Rebel XTi or EOS 40D you end up with the 35mm-equivalent of 1920/5.6, a 2688/8 with a 1.4x extender, and a 3840/11 with a 2x extender. If you need to focus any tighter to your subject you'll have to hop a plane and fly there."
As if the nearly 100,000$ price tag didn't make you pass out, you would be paying 7,300+ in tax if you live in NY, and 500+ for shipping, and thats if you live within the same 40 mile distance from NYC like I do.
I might just buy a ticket for EuroMillions on Friday now, 93 million quid, I might be generous and lend the lens to a few people, shipped on my private jet of course!
Anyway, it's a prime, so keep in mind: zoom with your feet ...
and what comes in handy with the 1200's hood: a 2.8/300 and the rest of my lens kit fit in the hood of this one. Really this is more than 1200 mm of EOSfun
