best ultra wide angle you can buy, there is no competition.

Great color; sharp; also on a FF

This is an outstanding lens. A bit pricey... but nothing else really compares to it.

I like to use it for action shots. I'm in the military and sometimes its not easy to back away to get the whole scene so the wide angle REALLY helps.

The widest prime lens in the Canon catalogue is a real gem: the EF 14mm f2.8L II USM, now in an improved Mark II version, delivers ultra-wide coverage without any of the distortion of a fisheye.

"There's not a lot of point to use this lens on a crop sensor because in that case the magnificent field of view, amazing sharpness and brilliant distortion control get lost in the cropping of the image circle.

I tested this lens on a full frame camera at every aperture under a variety of settings. The lens was not real sharp, even in the center, until around f/8 and showed a lot of distortion towards the edges regardless of the aperture setting.

Fast auto-focus; Superior build quality

Gary Wolstenholme reviews this ultra-wide angle 14mm f/2.8L II USM lens for Canon full-frame cameras.

Great build quality; Excellent sharpness in the centre; Relatively lightweight

Expensive; especially when compared to alternatives; Sharpness towards the edges of the frame could be better

Fantastic lens for interior pictures. No noticeable barrel distortion, great image quality. I had been using a Nikon 14-24 but was getting frustrated spending time correcting the barrel distortion.

Consistent Output; Fast / accurate auto-focus; Insignificant Distortion

Try using the 14mm on a full frame camera without a major grin on your face.

I gave this lens the top rating. It is expensive and lots of people will knock it a little for this reason. But I find it to be the perfect tool for some types of jobs. It is a specialty lens for sure. I shoot real-estate photos as part of my business.
