A great lens. The sweet spot and optimal f stop is F8. It's amazing. The color is amazing. You will love this lens if you shoot landscapes or group shots. The color is stunning. And I am very impressed by the non distortion of this lens. It's superb.

Using it mainly for Landscapes as it gives me the extra width that I was used to on my 17-40mm on my Canon. Bought it to use on the X-T1 and it is lovely. So far looks amazing but as others have said it's worth stopping down a bit although to be fair, we're always looking for max DOF with a lens...

Durable

One of the best lenses Fuji make, worth every penny.

Nice and sharp @ f4, even along the edges and in the corners. Even better stopped down. Blows away other ultra wide's I've had (Tokina 17-35, Sony FE 24-70, Nikon 16-35 f4). I wouldn't hesitate to buy again. Highly recommended. I use it on a X-E2.

everything; I'm yet to be disappointed by a Fuji lens

a little large on a X-E2; but not a problem

A very very nice lens. Excellent for travel and landscape photography. Image quality is superb with enough light. The only thing this lens is missing is a weather sealing. In very humid conditions and locations, moisture will get inside. So be careful when you take this lens.

Awesome lens

Fantastic wide angle lens! Top sharp, well made. No complaints. Sale price was good too.

Gary Wolstenholme review this ultra wide-angle lens for Fujifilm X-Series cameras.

Outstanding sharpness; Robust build; Lightweight; Retro design; Low CA

Possibly a touch expensive at launch; Falloff at 10mm

The Fujifilm XF 10-24mm F4 R OIS is the widest lens in the fledgling XF line-up and is therefore worthy of attention from anyone interested in capturing everything from landscapes to up close and personal street photos.

If you read our analysis so far, you may have noticed a few negative findings but this has to be seen in a context. Ultra-wide lenses are never flawless and the Fujinon XF 10-24mm f/4 R OIS is actually one of the best representative of its species.
