(Please click on the photo to see it at 100%) Everything in life is a tradeoff. This gives the 7Artisans some advantage in terms of corner image quality. Therefore it has a bigger image circle and the micro four thirds version only using a smaller image circle closer to the centre. I believe the reason why the 7Artisans has better corner performance is because the 7Artisans was originally designed for APS-C cameras. ![]() Even at f/5.6 it’s still a bit soft when compares to the 7Artisans. Comparing this with the Samyang, surprisingly the Samyang is nowhere as sharp as the 7Artisans. If you stop down to f/5.6, the corner sharpness become really good. (Please click on the photo to see it at 100%) Looking at the corners, for a fisheye lens, the 7Artisans is quite sharp at f/2.8. However, the Samyang is noticeably sharper than the 7Artisans even at it’s maximum aperture (f/3.5), stop it down a bit and you get very sharp result at the centre. Stop down to f/4 – f/5.6 and the sharpness improves quite a lot. At f/2.8 it is a bit soft but still very useable in my opinion. I’ve borrowed a Samyang 7.5mm f/2.8 fisheye lens from one of my reader (Thanks Sean Gray!!) and did some comparisons between the two lenses.įirst, let’s look at the image sharpness.ħArtisans’s centre sharpness is quite good. I think the reason we have this issue is because one of the tap on the lens mount is shorter than it should be, and that allows you to put it onto the camera in the wrong angle. And what even worse is, if you didn’t notice the lens has not clicked/locked onto the camera, you may end up dropping the lens. While it may not cause damage to your camera/lens, you might be confused why the lens doesn’t “click” when you try to mount it onto the camera. I have to say this is the first time I noticed this kind of issue with all the micro four thirds lenses I’ve used. Check the end of my unboxing video and you’ll see how I could mount it onto the camera incorrectly. But one thing that is not so common, and actually a bit of issue is, you could kind of mount the 7Artisans fisheye lens onto the camera even if you put it on at incorrect angle. This is pretty common for a lot of third party manual focus lenses. Much better than my Nikon AF 16mm f/2.8 fisheye at least as the lens cap for that lens can easily fall off even when the lens was brand new.Īs I said at the beginning, the lens has no electronic components and therefore it doesn’t have any electronic contacts at the lens mount. It would be interesting to see how it will be like after say 6 months or 1 year but so far I think the lens cap is perfect function wise. The lens cap is still tight enough that I don’t think it would fall off by itself, but it’s not super tight anymore so I no longer worry that I might damage the lens hood when I take it off. But after using the lens for about a week, the lens cap has loosened up a bit and now I’m actually super happy with it. I felt I would easily damage the paint on the lens hood every time when I remove the lens cap. When I first got the lens, I wasn’t too happy about it as the lens cap is really tight when attached to the lens. The lens cap is made of soft plastic and does look/feel a it cheap. But I don’t see why anyone would want to remove the lens hood as the lens hood provides some physical protection to the extruded front element and you’ll also need the lens hood for the lens cap to attach on to. The lens has a built-in detachable metal lens hood which is solid and nice shaped. As I’m mainly a photographer, I would certainly prefer the aperture ring to have clicks or even better if they can make it a switchable design. The aperture ring has a click-less design, which seems to be a trend for most of the lenses from China for some reason. The aperture ring and focus ring are both smooth but I feel there is a tiny bit of play when I try to rotate them. The size is fairly compact but feel very solid thanks to its metal construction. The 7Artisans 7.5mm fisheye lens is a manual focus lens with no electronic components inside. ![]() Being a Leica M user, I might review that lens in the near future as well, but this time, I’m reviewing one of their other lenses first, it’s the 7Artisans 7.5mm f/2.8 fisheye lens for micro four thirds camera. Their 50mm f/1.1 M mount lens is definitely the one most people are excited about as it’s a super fast lens for the Leica M mount and the price is really really cheap. 7Artisans is another new comer and they have just released a bunch of lenses. Mitakon (Zhongyi), Laowa, Kerlee…etc and some of them have already established a good reputation as a lot of their lenses delivers not only good quality but also being very cost effective. In the last few years, we have seen a number of new lens manufacturers from China. 7Artisans Official Amazon webstore: (Note: I’m not affiliated)
