The lens that I’ve been waiting for, the Zeiss 100mm f/2 MAKRO PLANAR ZE, is now in stock at Amazon.com for $1,843! (BUY IT HERE). The price is cringeworthy. Quality? 2nd to none!
According to what I’ve read online, this baby offers high resistance to flare and is a very strong performer at infinity, even though it is a macro lens.
The Canon has built in ‘Image Stabilization’ and autofocus which might make a difference to those who depend on those functions. The Zeiss is manual focus only… but keep in mind when shooting video there is no autofocus.
