We've seen the 2010 Super Teles and the pricing are... mind-boggling for good reason.
With that in mind let us talk about the most popular super tele prime used by many talented wildlife photographers worldwide: the EF 400mm f/5.6L.
It is a good long lens that disgustingly easy to hand hold but lacks two things: Image Stabilization and Weather Sealing. Which is odd as it is most likely used outdoor.
So what if tomorrow Canon announces a EF 400mm f/5.6L with 4-stops of IS, weather sealing, weight reduction of 28%, improved build quality, improved image quality, closer minimum focus distance & other improvements found in the 2010 Super Teles would this be worth $2,175-2,300?
Price assumption is based on the pricing strategy of Canon for the 70-200 f/4 vs 70-200 f/4 IS & 70-200 f/2.8 vs 70-200 f/2.8 IS II.
