Pros: I weigh the quality on aps-c and in my opinion a low price.

Cons: I would say that over f10 drops badly in quality, but if you know you avoid it.

Opinion: I would say it was a surprise this lens with its unexpected quality. I would say it was one of the components I tested for the new March article on Photographers. Switching from a medium format to an aps-c was not easy, but in the end you get used to it if it is the only system you use. I've tested several lenses, but here we're really on another level of quality at an affordable price. And if you're skilled in post-production, no one will notice that you've shot with an aps-c, especially if the images are posted online at 1920 pixels, where they look great. As always, the colors are rather flat and the contrasts don't shine, but this is only true if you don't work on the negative in camera raw. For me, this is an exceptional lens, free of defects and capable of offering extraordinary quality.

Pros: Very light, very well built, excellent dials, excellent cost ratio and very high performance.

Cons: On the 40MP Fujifilm sensor, some marginal chromatic aberration in very extreme situations, lens hood lock system, no aperture ring marked for the Fujifilm system, attention on the precise setting of the AF point.

Opinion: The Sigma 10-18 Zoom is here. Tested with my Fuji X-H2 40MP. Very quick tests against the Sigma 12 1.4 vs Fuji 8-16. The Fuji 8-16 remains a Premium lens with no chromatic aberrations: the images are cleaner, but the heavy and bulky lens also costs three times more. The Sigma 10-18 Zoom as a construction looks like the brother of the Sigma 12 1.4, the Sigma fixed with very slight advantages in sharpness even if you have to zoom a lot to see a difference, but you notice it in the corners, which one to choose between a Sigma 10-18 vs 12 zoom 1.4 I find it really difficult to answer the Sigma 12 1.4 is definitely more suitable for indoor photography also for astrophotography, but with doubts about the exact AF it may have a problem with the firmware. Less performing point at 10/11mm causes distortion, even visible, some chromatic aberration in difficult light situations. Another point to be very careful about the precise AF point settings?, I prefer to use Zone AF on this wide angle zoom. For very high demands, Fujifilm extreme wide-angle lenses unfortunately only offer the 8-16 zoom as a Premium lens, there is no lighter and more transportable alternative, for example Fuji 12 1.8, 10-20, 2.8, it's a shame, Fujifilm has a nice 40MP sensor but then partly the lenses that are not available, you have to look for alternatives from third-party suppliers with a 40MP sensor, A great commitment. Note: great value for money and what it offers, so for me a great optic to recommend, but definitely not a Premium optic. I have done more tests definitely to recommend the Sigma 10-18.

Pros: Sharp even at full aperture, very compact, very light, non-existent chromatic aberrations, possibility of mounting screw filters, max aperture f/2.8, tropicalized, AF on a par with native lenses

Cons: Zoom ring in reverse (but you get used to it quickly) and little else

Opinion: A truly brilliant lens that, in my opinion, fits perfectly with what is the philosophy of APS-C cameras: compactness and lightness. Combined with the superb image quality on most of the frame, the tropicalization and the possibility of mounting common screw filters, it makes it an almost obligatory choice for those who want a quality wide-angle in the APS-C segment. Of course, if it cost 70/80€ less like the Tamron it would have been ideal but even if taken at 700€ in my opinion it is a bargain. Also because it is smaller and wider than the aforementioned competitor. The zoom ring turns backwards and it's a bit strange but you quickly get used to it having a limited focal range. The f/2.8 aperture allows you to take several photos at night or some close-ups without expecting a sensational bokeh. Finally, like almost all the latest Sigma lenses that I have been able to analyze, the image performance and sharpness are very satisfactory and worth every penny. Vote 10.

Pros: Sharpness, contrast management and chromatic aberrations, in short, technically perfect

Cons: I would have preferred a bit of Premium materials given the cost, but nothing that affects everyday life

Opinion: Really nothing to say, for quality, size, weight. In the hands it gives the feeling of being a bit cheap, but it is solid. The lens hood is interlocking and not half bayonet. It is possible to mount filters, it is not obvious at these angles of view. It is a fun lens, which for some moments of the wedding, where I specialize, is useful and does its duty. And he does it well. On the stock market you forget it, but when you need it ... You climb it up and the world of extreme wide angles opens up. I would definitely buy it again.

Pros: Absurd sharpness

Cons: I don't think you can expect any more

Opinion: Mounted on the camera 10 minutes ago, I was already well informed about this lens, but beyond the opinions already present on the net that I quote 100% I just want to point out the first thing I look for in a lens, which is sharpness. Well.... This variable blew me away! Never seen such a thing on a wide-angle lens. I think it will be mounted on the camera body for quite a while.

Pros: Lightweight, not bulky, sharp, non-vignette

Cons: Nobody

Opinion: I've owned it for about two months, and I've already taken a lot of photos of it, from some set portraits, to a bit of street, and mainly architecture, albeit on the road. This was the purpose that decided to buy it, first of all, to be able to use it to take cues and glimpses that would be difficult to obtain otherwise, and to minimize falling lines as much as possible. Of course, if you don't level it perfectly, the deformations will appear, but they can certainly be corrected in post-production. Another thing that really surprised me in a positive way, is that it doesn't even vignette at full opening. It's not just because it's a recent acquisition, but I have to say that I replaced it a few other times during a cruise I did in April. I had the 18-55, and the 35 1.4 to choose from... And it continues. Maybe it's because my type of photography, in this period, prefers a certain type of subject. The fact is that for what it costs, and for what it yields, combined with a truly negligible size and weight, it is a lens that ensures satisfaction.

Pros: Portability, Sharpness, Weight

Cons: Nobody

Opinion: I made an apparently 'strange' choice: I replaced the Sigma 14-24mm Art with this little gem. Strange because the Art is a stellar lens and excellent lenses should be kept. But for a while now, I've been prioritizing portability over any other feature. Because portability often makes all the difference, it makes you put a lens in your backpack that, otherwise, stays at home. There is no doubt that the 10-18mm is a miracle of portability. And also image quality if you consider the size.

Pros: Very light, solid and focal length

Cons: Nothing, apart from the aperture ring.

Opinion: Switched from Canon 1 dx to fuji xt3/4 less than 1 year ago, at the beginning shock, then taking the measurements you appreciate the philosophy and the study behind the whole system, despite being apsc, but with the noise reduction of the latest version of lightroom I fear nothing. I was going to buy the tamron 11/20 but I was right to wait for this invisible gem. Great Sigma!! I'm waiting for a tele... maybe a 50/140....

Pros: Very small, very light, very sharp. And it's cheap for an f2.8 too.

Cons: Zoom ring that turns backwards, nothing serious, you get used to it.

Opinion: I'm just stunned! The sharpness is impressive and this already at f2.8, and over the entire focal range. Extraordinary. The fact that it doesn't have a bezel I can understand is annoying, especially if you use Fuji from the XT series. But I come from a time when I was using Sony, and there were lenses without a ring there, so I learned how to use wheels. It's true that even on the XE4 not seeing the aperture without putting the camera to the eye is a bit annoying, but I photograph 99% looking through the viewfinder so, at least for me, it's a false problem. On the XH series, on the other hand, the diaphragm can be seen on the upper display, and here the problem just doesn't arise. Slight vignetting at TA and distortion present, but very well corrected with C1. The fact remains that, as I had seen in Abbot's and Frost's tests, the sharpness is exceptional, especially in a zoom that, to see it so tiny, seems a compromise in all its parameters. Amazing what this little gem pulls out, which I remember, is an f2.8!! The corresponding Fuji, which I've used for years in both versions, doesn't even come close. And the Fuji, like the Tamron, which by the way starts at 11mm, is also more expensive, bigger and heavier. Absolutely passed with full marks.
