Didn't think I would, but I LOVE THIS LENS. I prefer my fast primes for editorial work, and my go-to kit for editorial would be 16-23-35. But, if the shot's got to be a landscape or architectural interior, the 10-24mm is one of the finest wides I've ever worked with. It's shot more covers than any of my other Fuji X lenses, so for commercial/print reasons this is one of the most useful lenses you can own IMHO, especially if you deal in landscapes and interiors. You'd have to go tilt-shift to get better performance. It's funny because I actually never really liked the 10-24, and you'd probably never see me walking around shooting with this lens "just for fun." It has been, and will continue to be, a real moneymaker for me though.
Whether the 10-24mm truly shows less distortion than Canon's 16-25L or whether it's just got better and more aggressive correction for distortion on-camera, I just don't know. What I can tell you is that end result, my wide shots from the 10-24m show markedly less distortion, specifically a LOT LOT LOT less barreling. It's a heck of a lot easier for me to make interiors look "straight" with a properly used Fuji 10-24.
I actually much prefer the sharpness, IQ, and "pop" coming from the 14mm or 16mm so if you're just looking for a wide to round out your kit and you can live with a prime that is a little less wide, I'd suggest your money would be better spent on the 14 or 16mm. But if you've just got to be able to get a few mm wider, the 10-24mm is a good performer. It's reasonably sharp, manages distortion well, and isn't super flare-happy. The IS works quite well and the lens is very good, although somewhat overshadowed by its prime stablemates. As others have noted it's much larger than its siblings, and it takes a Canonesque 72mm front filter. It still is't huge though, and manages to be a little smaller than Canon's comparable 10-22EF-S, with much better build quality.
But enough babbling. Here are a few shots with this lens from the last year:
At 14mm:
At 10mm. This one made cover for Hawaii Magazine:
At 10mm, ISO 1600, and f/8 indoors and handheld. Taken around late afternoon. This made another cover for Hawaii Home +Remodeling:
At 14mm. This was another cover (I had a lot of interiors to shoot in 2015):
At 10mm, cropped in a bit I think:
This one was around 18mm:
Like any other wide of course you've got to manage your horizon, and camera tilt/yaw to get the most out of the lens, but if you do, it's great!
I prefer primes or fast lenses so I have the versatility to shoot in low light, so while the 10-24 isn't a lens I use out of preference, it's been a solid performer and other than the whole "F4" thing, I've no complaints! And no, I would NOT want to own a faster but much bigger f/2.8 version of this lens anyway, so even that part's OK I guess? Hope this helps!
