I'm personally not too crazy about a 14-24mm f/2.8 lens. I would much much rather Canon release a further updated 16-35mm f/2.8 III, specifically based on this insane lens patent:
16-35mm f/2.8 IS Pro Lens.
f/2.8 3 ED elements 5 aspherical ones, and sharpness that rivals the 14-24mm wide open, AND image stabilization!
Internal focusing, low vignette.
I really would much rather have greater flexibility and greater focal range than an ultra wide angle that only does ultra wide, and worse than this proposed lens at that.
Anyone else feel the same way?
If they can make a great 16-35 I would be very pleased. The 14 prime is a great lens, and an overlap with the 24-70 would mean I could avoid changes lens occasionally.
