Canon EF 16-35mm f/4L IS USM

Pros: There's an important notice in Opinion section! Incredible sharpness across a frame on every focal length and aperture. Low price that seems to be the lowest in connection with sharpness it delivers among all L lenses I've ever used. A weather sealed body with a gasket, a comparatively small and convenient lens hood (takes not so much space in my bag like 17-40 lens hood), popular and affordable 77mm filter thread, image stabilization that's quite handy, image quite compact for an ultra-wide zoom.

Cons: Can't make coffee & toasts.

Opinion: https://yadi.sk/d/JRe0ArOkhL6nr Here are some raw (*.CR2) test shots with 16-35/4 L IS lens on my 6D at apertures 4.0 and 8.0. These shots are more telltale than words. Simply download files (find and press a downward arrow) and open locally with smth like DPP or ACR. I must only add that having experience of using 5 L lenses and 2 ZE lenses I was shocked by sharpness of this gem from Canon when I took first shots. Natural color reproduction, high contrast, uniform sharpness across a frame with only slight degradation in outermost corners, not a trace of softness of any visible CA, low and easy correctable distortion and vignetting. Beware of minor field curvature esp. on the long end. For max acuity nail focus on a side-located object through LV. Speaking emotionally I think I'm lucky with the lens or Canon finally made an almost perfect and affordable ultra-wide zoom or both. P.S. check on my flickr page for shots taken with this lens (still pending). An important notice (for pixel peepers)! I've been shooting with the lens for a week and that's what I found. 1. IS may and does degrade IQ making sharpness across a frame non-uniform. I believe IS in a ultra-wide lens acts like a tilt-shift unit making unfavorable and uncontrolled shift movements at the moment of capturing a shot. OTOH IS on mode is fine for videographers. With disabled IS the lens still captures sharp images as usual. 2. The lens has got a mild field curvature on focal length between 24 and 35 mm maximizing at 35mm. Hyper focal focusing is not effectively applicable with this lens. Corner objects are sharper if they closer to the camera. Increasing aperture makes close objects more sharper than ones on distance. So keep this in mind and use LV focusing or focus bracketing techniques. It must be mentioned that it is common for wide and even normal lenses. N.B. I won't decrease the lens rating because I think that these aspects are not negative yet rather its peculiarities. Simply keep them in mind and produce great pictures with this great lens.
