Actually, I had only bought the lens to bridge the waiting time for the Nikon Z 26 mm pancake. I usually shoot with a Z6 for which I also own a few lenses. For short trips with hand luggage only, I bought the Z30 because of its small dimensions and low weight. Actually I wanted to wait for the 26 mm Nikon but now we were on a short trip to Antalya in Turkey and the 69 euros for the lens were not too expensive for me. What can I say: I am very impressed! Of course, the focus is only manual. But you get used to that very quickly thanks to the focus peaking of the Z cameras. Since - at least my copy - has a clicking aperture, focusing with an open aperture is not a problem. When the aperture is open, the edges are quite blurred. But I actually only use the open aperture for portraits or for shots where I consciously only want the center to be sharp. I take most street photos at aperture 8. With this lens, the infinity setting is actually adjusted once in a while. With an aperture of 8 and a setting of approx. 1.7 m, everything is actually sharp so that you don't have to correct anything. The pictures with the motorcycle were taken at f/2 and f/8. The light mast at f/2. All other photos at f/8. It's really amazing what you can get out of this optical construction without any electronic intervention. All photos are unedited and saved as jpg in the camera.
Absolutely awesome for the price!

The lens is made of metal and makes a solid impression. Aperture and sharpness are set manually. Works perfectly on a Nikon D50 (DX sensor). With an open aperture in backlight, very pronounced reflections in the lens, which decrease significantly from aperture 5.6. This gives a certain retro look. Example photos attached. A small drawback: the aperture ring has no detents and can be accidentally adjusted.

needed something small and cheap as I'm tired of carrying around a full frame DSLR. I have a small Fuji camera and this lens. I expected the quality of the images to be "decent" but what I got is very good to excellent. I don't hesitate to use the lens wide open. Focusing is easy and sharpness is very good wide open. My Fuji is 16MP, so the lens would probably be a bit less sharp with a 24MP sensor. I think wide open sharpness is best for medium distances. 2-4 m away from the camera. This is perfect for me as I'm not a flower shooter. When stopped at F2.8 or F4, the lens will be sharp throughout the frame. I love the way it glows when the sun hits the glass. The photo will look warm blurry. I miss that with modern expensive lenses. I can wholeheartedly recommend this lens. I will definitely be ordering the K&F Concept 17 and 50mm lenses.
Great little lens

For this price there are only plus points for the optical performance of the lens. I added two shots Jpg (unedited) with exposure compensation +0.7 The shots are taken at close range with aperture 2.8 and 4.0. I put the sharpness on the calyx and on the right side of the zipper. The pictures were taken with a Nikon Z50. The image quality convinced me, as did the processing of the 50/2.0mm lens. Norbert Kaufman

In my test, no brick walls were photographed, 100% cropped in the corners, or pixel peeping was done. It is a diagonal fisheye, so there are no spherical images as with circular fisheye. The 180° picture angle is therefore only available in the picture diagonal. The K&F Concept 2.8/11 was simply attached to the Nikon Z 6II and photographed with it, then evaluated purely subjectively. K&F Concept is a Chinese company that manufactures lenses. When you think of Made in China and a Chinese company, you think oh dear, here comes a lucky bag. You think they can do something, prejudice is such a thing, completely unfounded here. How much of what we have in our hands comes from China, since many companies have outsourced their production to Asia. But I've also experienced completely different things, but also with the top dogs themselves. The lens is milled from the whole, pure metal housing, real coated optical glasses of the finest quality and at a great price. The lens is well calculated, at least for the price range and a diagonal fisheye. If you think you can get more from the top dogs for 5 - 10 times the price, you should try it. Sharp right into the corners and that from aperture 4.0, minimal weaknesses at 2.8, but this is to be expected with a UWW fisheye, nothing dramatic. With a UWW simply set to aperture 4 or even better 5.6 and everything is sharp from front to back. Close-up limit is 17cm. The lens cover is also made of full metal and perfectly protects the curved front lens. The front lens is so curved that no filters can be used, as with almost all Fisheye. It is also a purely manual lens with no electronic contacts or data transmission whatsoever. The whole thing weighs 512gr. without lid (weighed on precision scales), in the Nikon Z variant, but is still small and compact. Fits perfectly to the Nikon Z6II and is super balanced. Working with the lens on the Z 6II is great fun. You can adjust the aperture wonderfully (absolutely smoothly without a grid), read the sharpness range on a scale (where else does that exist today). It comes with a front and back cover, a guarantee card/instruction manual (who needs them) in the finest Chinese writing, and anyone expecting anything else is out of place here. The whole thing in a small, white box, absolutely shockproof, embedded in two Styrofoam shells. The bayonet connection is also made of metal, just like the permanently installed lens hood. The image look is a bit like slides or paintings, you have to like it, that's the character of this lens. The entire lens looks a bit like from days gone by in terms of its optics and feel (all metal). But it is a price-performance hit and can be used as a fisheye, UWW & panorama wide angle if you know how to use it properly. The advantage of a diagonal fisheye, when used correctly, you can also achieve straight lines. It is very suitable for architecture, see the picture of the side view of the church. When looking at the side view of the church, I was surprised how well this works. I give 5 stars because for this price and in this quality there is nothing better to get at the moment, above all the image quality and the versatility of this lens are convincing. That's the most important thing in a lens. You can't go wrong here.

What more could you want for a 60th birthday on Black Friday. Since no microchip is included, the device prompts to switch to manual mode. It's a lot brighter than the original 16-50 f3.5 on my Z30. The lens seems as good as a Nikkor, I don't have enough perspective yet but the photos I've taken so far inspire me with confidence. The quality is beautiful, well packaged in a beautiful and classy box.

I'm using this on a full frame Nikon — I don't know how accurate it is that it's f/0.95 as there doesn't seem to be any difference if you set it to f/1.2 or whatever, but as Lens advertised as a cropped sensor lens, this works really well. It's not the sharpest open goal, but then you know it's going in. When you consider the limitations of use, it's actually very good for the price.

use the fisheye for panoramas and occasionally also use the fisheye effect creatively in normal photos. Important to know: the lens is purely manual. No auto focus and no aperture control. And unfortunately no data transfer either. In practice, however, this is not so bad. In almost all cases I set the focus to infinity and stop down to F8 - F11. Everything is sharp from about 1m. If you want to focus more closely, the missing automatic aperture must be taken into account. The focus peaking of the Z7II no longer works properly when stopped down. You should therefore focus with the aperture wide open and only then adjust the aperture. So nothing for snapshots. The image quality is good, but should be sharpened a bit in the image processing. I photograph exclusively in RAW format and develop with DXO-Photolab. The camera-lens combo is not yet available here, so automatic corrections are not possible (also because of the lack of data transmission). In the manual process, however, a good - considering the low price even very good - image quality is achieved. The following is to complain about: - The aperture has no detents. As a result, it is easily misaligned and an exact repetition is basically not possible. - The lack of automatic shutter control is annoying for fast freehand shots. - The lens does not transmit EXIF data. If you want to know which lens you used for a picture, you have to enter it manually. - The focal length is cheated. It is more like 15mm. Conclusion: great prize for panorama photographers and for use without time pressure, but not suitable for quick snapshots.

At first I was skeptical whether you could get a usable fisheye at this price. After using it for a few weeks I can say yes you can. No autofocus, of course, but with the magnifying glass function on my Nikon Z50, that's irrelevant. The lens is not intended for snapshots, and when selecting an object, you can manually focus so precisely that the images are razor-sharp. A lens just for fun, and the joy is undiminished. In short: clear purchase recommendation.

Functional optics and above all sharp also at the edges. Excellent quality of materials. Precise and no backlash. Also perfect for video, membrane ring without shots, excellent also the ring of MF liquid and without indecisiveness. I repeat excellent color balance, absence of dominants. Just mole aesthetically not pretty, but that's okay.
