Gets the job done. Good for the price.

Great fisheye lens. FYI if there some color issues, take the lens filter off. Having flat glass in front of the curved glass for the actual lens messes with the color and lighting in a weird way. Most reviews about poor quality are probably using the filter when they shouldn’t. Other than that, the sharpness is to be expected for a fisheye lens of this size.

It'a really cheap so I can't complain. However it is really just a toy, don't expect anything too nice from it.

Item: AstrHori 10mm F8 II Ultra Wide Angle Fisheye Price: $ 79.00 at time of review on 02 12 23 I was pleasantly surprised, given what I felt were reasonable expectations, when I received the AstrHori ultra-wide lens. I say that because this lens, while not equipped with the high quality optics I have in my studio lens inventory, is most certainly very usable and with a very attractive price point. I was able to easily ‘line up the dots’ and mount the lens on my A6400, which is my prime video-recording camera in my studio area. The close-focus distance is (0.3-meters), about (11.8-inches). I tested the lens on my camera and recorded a test segment. The 150-degree view contrasted quite noticeably with my 18-mm to 135-mm Sony lens, which is usually set at 35-mm for a somewhat ‘flat-field’ recording. If I were to describe the sharpness and clarity of the lens, based on the results from my studio test video, I’d say it was ‘adequate’ but far from a quality lens. I’m definitely going to use the lens. But it will probably be for ‘short video segments’ and if for still work, in a very bright and well illuminated setup. This f8 lens definitely benefits from ‘competent lighting.’ I noticed that in my studio video test, I was well illuminated with two panel lights and my image was decent. But as the lights dropped off on each side, the image quality suffered. The AstrHori lens, in my opinion, is an excellent value. While not a high-end prosumer lens, it will allow you to create still or video imaging with that ‘intentional distortion’ that only a fisheye can provide. And it provides that at an extremely reasonable price. The downside to a lens like this is most certainly its f8 fixed aperture. If I were recording outdoor segments, I wouldn’t expect great results with marginal light levels. However, when I saw the results from mounting this lens on my A6400, I could see a future of creating video segments and still shots that could certainly augment my projects. Again, proper lighting can help make up for the f8 lens, and augment and improve the results. Overall, I was impressed and satisfied with the AstrHori’s performance. The utility of the lens certainly meets and exceeds my expectations for what I would call a typical budget fisheye.

Disappointed. I read the product description and saw the sample photos. I saw the fisheye images, the fisheye title, and figured my shots would be fisheye. But that's only for full frame cameras. It's just wide angle and crops the fisheye fish bowl edges off. I wish it was more clear in the listing.

As they mention in the listing, this has to be used with the "release without lens" set to "enable". I had some trouble finding that on my Sony A6500 - Sony put it, oddly, in the video part of their menu. But with it enabled, the lens was usable. The listing describes it as f 4.5, and the title as f8. I just set the camera to P mode and let it sort out what the actual aperture was. It worked fine. There is some semi-fisheye or barrel distortion, but I was able to correct for that with a manual lens correction in Photoshop. The lens does have a focus ring. At one end it says 0.3 (meters, I would guess) although the listing says it focuses to 0.45 meters. I found that at the other end of the setting (infinity) everything from very far away to pretty close was adequately sharp. Even things only a foot or so (0.3 meters) were tolerably in focus, if not exactly crisp. They could be made sharp with sharpening software. On the other hand, at the close focus setting, although very close things did get sharper, distant objects (more than a couple of feet away) started getting blurry. At large distances they were quite blurry. So in actual use I'd just leave this thing set to infinity unless I had some special need to have a very close foreground item in crisp focus. There was very little vignetting, which is good, since automated lens corrections really aren't available for this lens.

Overall, this 10mm is a great value. It doesn't take a lot of skill to appreciate either since (with the small aperture and wide angle) your photos will almost always be in focus no matter what you do... just make sure you have a lot of light. If you do have more skill you can push it even further with long exposures and lower ISO settings. It's also a rectangular and not a circular fisheye, so the fish effect can be managed in post production with distortion and vignette fixes (see first outside photos). Overall, this isn't a professional lens, but it is a tiny, take everywhere sorta lens that help you push your creativity and barely put a dent in your pocketbook. PROS: + Adds a fun new perspective to your photography + Allows for sweeping panoramas, large group shots, 3 walls of a room (much wider than even the 18mm kit) + Fisheye distortion is manageable in post production (see first 2 outside photos one with and one without distortion correction) + Wide angle is almost all in focus at f8 from 1 foot to infinity without needing to focus much. + Wide angle is more forgiving in camera shake than telephoto. + Good optical performance with little to no light flare. + Sony cameras offer focus peaking so you can easily optimize focus manually if you'd like + Tiny body cap size makes it easy to keep a functional lens on the camera at all times without taking up any significant space. CONS: - Stuck at f8 means you need a lot of light, long exposures or very grainy ISOs. - Focus ring doesn't have detailed markings, so you're sorta just guessing until you hit the hard stops on either end. - You will need to go into your camera settings before you use it to allow the camera to fire without a lens (since this has no electronic communication with the camera) - Vignetting is fairly strong. - Can't close/macro focus, limited to about a foot on the close end.

Definitely a cheap lense. Decent quality for the price but almost more of a toy than a lens for real usefulness.

El diseño es muy bonito. Sin embargo no resulta práctico para quitar y poner de la cámara. El barril de enfoque es poco preciso y la óptica no es buena. Deforma mucho y no es aceptablemente nítida.
