I'm honestly surprised by the negativity around price with this lens. It's a niche lens with a complex design and near flawless image performance that demands a large price. So be it I say. I'd like to purchase it, but two things will prevent me from doing so in the short term:
- Canon does not have a high megapixel body yet to take advantage of this lens. Granted, there are certainly other benefits such as color rendition, contrast, edge-to-edge sharpness, but my guess is that it really shines with a high megapixel body
- Manual focus through the viewfinder on newer Canon models is an exercise in frustration if you are extremely anal about perfect focus placement. Forget about it on the 5D III, as the viewfinder presents an image with an f-stop well smaller than large ones on prime lenses. I have a 1D-X, but have yet to try one of the focus screens that can be purchased, so maybe I can go that route.
Regardless, I find this thens very intriguing and hope to be able to rent a copy to try at some point. I will reserve any judgment on price until then.
