This is an awesome lens: the pictures are sharp, the colours vivid, the contrast excellent, the vignetting minimal (no small feat for an ultra-wide-angle lens). I use a Leica Vario-Elmarit 14-50 as a standard lens, which is still a bit sharper.

Love this lens! The clarity is amazing and like one of the other reviewers said, it is tough to go back to my standard lenses after using this one. The lens is heavy and can put quite a strain on the neck. It is great for capturing crazy angles in architecture photography.

This is an awesome lens! There is no pincushion or barrel distortion, nor vingetting at any zoom setting. I sometimes use it for art photography, and the edges of a framed piece of art line up perfectly with the image edges. It demands a different way of shooting.

Simply incredible quality -- both optically, and build quality; Water-resistant design.

Big, heavy, expensive; I'm a prime shooter, and I use this lens 90% of the time at 7mm, 10% at 14mm, and almost never in-between.

From shooting ATT Giants Stadium to an Orthodox Church in low light this lens is amazing. The 7-14mm almost acts like my 2.0 14-35 and 35-100 lens. It sucks up the light to produce a very clear image from edge to edge with spectacular colors.

"This lens has magnificent scope and the glass is absolutely tack sharp. The continuous f2.8 allows for brilliant colour and contrast even in low light conditions. By utilizing the level gauge in my E-M5 mk II viewfinder there is little to no noticeable distortion at all.

This is an amazing lens. My experience is in-tune with the reviews written here and elsewhere, it is absolutely beautiful. I purchased right before a trip where I would be in numerous cathedrals and wanted to be able to capture a very wide (or tall, in portrait) field of view, in low light.

Searching for imagery with these lenses starts off slow composition-wise and sneaks up with a bang right up to your eyeballs. This is ONE incredible piece of glass. Finding compositions with this is astounding once you find your groove and mood.

feels good heavy lens , but really bad Quality the lens bad with any kind light , the light makes reflections with bad blue dots every where in the images

Impressive Optics. Little noticeable barrel distortion. Optics appear to be just as good as my Canon 16-35mm L II. Having said that, I wish the lens design accommodated a filter so I could use a screw-on VND filter.

Ordered This Lens from WEX at 3.00pm and it arrived the Next Day at 11.30am. Amazing service. The Lens is unbelievably sharp at all f stops including f2.8. THE only downside I can find is being unable to fit my Lee filters to this. But I am working on a solution at the moment.
