[Nikon Z] Initially, I was not sure if I had made a wise purchase. Okay, it is a cheap, manual lens for my Nikon Z9. I already had a Nikkor14~24mm f/2.8 lens, but to use that huge lens with the FTZ adapter made the lens a bit ungainly for travel. But I was disappointed with the focusing of this new lens though the EVF. On the other hand, I learned by shooting at f/11 while paying attention to the distance setting on the external ring like early manual lenses, this lens works like a champ. Yes, it can deliver wide open but one has to be extra careful in focusing by whatever method you use. In any case, after getting the hand on how to focus, the results have surpassed my expectations. The clincher is the solidily constructed small size at a low price.

[77 mm (Front)] Great at what it does. For the price and quality, it's hard to beat. There are definitely flaws to the lens when compared to more expensive counterparts. But they would cost significantly more and not worth if you do not use them on a regular basis.

[77 mm (Front)] This is the perfect lens for ultra wide angle sunsets/sunrises. Very sharp. The biggest knock on it was that it doesn't have a very short minimum focus distance, but that doesn't matter to me. This lens is very well built and has a nice heft to it on my S5. Feels good to get away from auto focus once in awhile and going back to manual focus. For the price, this lens is wonderful.

[Full-Frame] Amazing lens, with amazing features, at an amazing price. I shoot mainly real estate media and the wider the better, this is the lens for my new Z6 II and soon Z9. . .agents noticed the difference right away and said they liked it. . .It's a HIT!! THANKS

[f/4] Bought this lens for doing Landscape and star trails. The lens really surprised me with the build quality and butter smooth turning of the focus. The Aperture stops have clicks which I like. I use this lens on my Nikon Z6II. Doing star trails with this lens is simply fantastic. The color rendition of the glass and beautiful star effects on bright lights simply looks great. Great sharpness too. Anyone looking into getting a wide landscape/Astro lens should really consider this lens. I plan on purchasing more lenses from 7artisans. As always, BH Photo service is second to none.

[f/4] I purchased both the 10mm and 11mm Artisans and found the 11mm definitely sharper when comparing lettering at 400% on a calendar in a room shot, however at 4 inches the 10mm was amazing. Purely by accident while shooting tests with the 10mm with the Lumix S1r I focused the camera on a pad of paper I had written notes on in pencil. Along side of the pad were 8 or so new Dixon pencils with gold stamped lettering all sitting on a dining room table cluttered with computers etc. At f8 with the lens so close the background dropped beautifully, but what astounded me was the detail of the lead pencil writing on the paper the the gold leaf stamping on the pencils. Photo had Color, contrast and even a bit of micro detail in the paper texture and writing. Based on this and other tests, this is a great lens for very closeup experimental work. Colors are accurate and vibrant. Lens is seemingly well corrected for this type of work with Capture one correcting purple fringes. For room shots and sharpness stick with 11mm unless you need the extra angle.

[Manual Focus] For the few dozen or so of us left that still love the fisheye look, this thing is perfect. Very affordable and the image quality is sharp. The edges are softer but that is to be expected from most super wide lenses anywhere near this price point. If you shoot with a wide aperture, you won't even notice since the background will always be out of focus anyways, so the edges don't matter much for me personally. I am using this on the R5 C and I can't begin to express the joy of being able to shoot fisheye with its full distortion glory in 8k up to 60fps in RAW. I have the 16mm canon prime but it's just not the same, I need that fisheye distortion.

[f/22] This 10mm fisheye is exactly what I needed for up close rocket launches. 10mm seems to be the perfect lens for the shots I'm taking of rockets that practically go over my head when they launch. I typically use it at infinity focus and 16-22 f stop on my Canon R3 or R6 (depending on where I'm at and which one I want the higher resolution on. I do a ton of launch photography and never shoot a launch without this baby.

[Manual Focus] After reading several online reviews of the 7artisans 10mm f/2.8 Fisheye Lens, I recently purchased one for my Nikon Z 8. It does not disappoint. This lens is incredible and a great value! It is a manual focus lens, but if you are shooting anything farther away than a foot, just set the focus ring to infinity. The lens has almost no lens flare and you can get a beautiful starburst even shooting at f/8. The images I have produced so far are very sharp. It is also a great lens for night sky photography, giving you a very wide filled of view of the night sky. This lens stays in my camera bag!

[f/4] Tried out this lens for some playing around with super wide angle for church interiors, ballparks, etc. Something I have not done before. Thought for the money it's not a big loss if the lens is not great. I was so surprised at the build quality and sharpness of this lens. Unless someone were really picky, I think you would be hard pressed to tell the difference between this lens and a much more expensive lens. I was also concerned about it being manual focus. I came to learn that with a super wide angle, it's almost always at infinity or I am shooting a still scene up close and auto focus is not necessary. Long story short, a great lens for a great price!!!
