I have decided to venture into the world of full frame and get myself a Canon 6D after having a play with one. I am particularly interested in the 6D's handling of noise in low light/ night shots. Once I get that, the next purchase will be a wide lens for it. I would prefer it to be a fast lens and at this stage I'm leaning towards the Tokina AT-X 16-28mm f2.8 Pro FX lens, based on reviews and on price. I was just wondering if anyone has had any experience with this lens and what their thoughts are on it? I would also be very interested in the same from anyone with a Canon EF 16-35 f2.8L lens and whether or not they believe it is worth the extra money. The reviews I have read are fairly split on this lens.
Any comments or advice would be much appreciated, thanks.
