Pros: Sharpness, weight, low distortions, price

Cons: No aperture ring

Opinion: I wanted to get the 8-16 2.8 Fuji, but before paying a considerable amount and not yet having clear the use I would have made of it I decided to buy this 9 mm, just tried, boom!!! I didn't believe that with just over 200 € I could have this quality. Is it perfect? No, but it has many qualities first of all excellent sharpness and minimal distortion at the extreme edges, I think inevitable with these focal lengths. I highly recommend it because at this price it is a must have if you like extreme wide angles

Pros: Compactness, f2.8 aperture, no distortion and price

Cons: For the cost absolutely nothing

Opinion: Of Viltrox I have the 75 - 27 F1.2 and the 13 F1.4 here these are of another level both body construction ,engraving and price But the small 9mm defends itself very well at such an extreme angle if used correctly it has no distortion it does not "stretch" you have sides of the frame Here you see a bit of chromatic aberration in extreme contexts though I have never tried the original 8mm and I can't do it a comparison but this 9mm costs 1/3 In conclusion the 3 lenses mentioned above in my humble opinion are EXCEPTIONAL ... the small 9mm VERY GOOD I highly recommend it Greetings

Pros: Everything, but above all small and light and sharp.

Cons: Too bad it's only APS-C

Opinion: Extraordinary optics, it completely enraptured me, on the Z50 II it is perfect. Fast AF, very minimal distortion, first-class sharpness, Flare management I would say well contained. And who expected it, from a negligible cost a robust and flawless performance. I also tried it on Z8, in DX mode, and even on its sensor it showed an efficiency on distortion and sharpness that I did not expect. The same 14-24 at the minimum focal length has difficulty at the edges, the small 9 mm in comparison plays on an equal footing. Absolutely rated 10 !!!

Pros: Sharpness, weight, size, price, brightness, distortion.

Cons: Flare resistance.

Opinion: A respectable lens in relation to the cost; with € 200 you take home a nice wide angle equivalent to 13.5mm on FF. Tried with the Z50II, on the road, I fell in love with it. A light and space-saving combination that allows you to take home excellent sharp shots with good color rendering. The only complaint is the resistance to flare but it can be safely overlooked given the low cost of this lens. The plasticky lens hood is also included, however, it does its job and attaches quite well. A lens that I highly recommend, well done Viltrox.

Pros: Sharpness, distortion-free, weight and size

Cons: I haven't encountered any yet

Opinion: I'm a fan of super-wide-angle lenses and, over the years, I've spent a good amount of money to buy them. I have had and used sigma, tamron and tokina and I have to say that none have the quality of this small and cheap Viltrox. It may seem impossible but with a figure of around 200 euros you can have a sharp 9 mm with a respectable aperture (2.8). Surely there are some features that allow it to have a lower cost (and by a lot) than the many other super wide-angle cameras on the market. First of all is that it is not a zoom, but anyway (we all know) supergrandongali zooms are almost always used at the widest focal length. The absence of the zoom also made the design easier to the point of ensuring almost no distortion. It lacks stabilization, but even if many purists will certainly find some reason to criticize this "lack" I would assure you that at 9 mm the stabilizer is completely useless. I use it daily and appreciate its focusing speed, aesthetics, optical and build quality. I rate it with a full 10.
