I generally don’t write negative reviews, but in some cases, I feel it’s important to share my opinion of something I bought that isn’t any good. I have a Fujifilm X-Pro2 camera, and I bought the 7artisans 25mm f1.8 lens. I wanted to try one of these cheap manual-focus lenses, made in China, because I’d heard good things about them. At around $79 or £79, it could be a good way to get a compact prime lens. (Amazon.com, Amazon UK) The lens is solid, seems well built, and heavier than it looks. It’s also quite compact; smaller than the Fujifilm 35mm f2 lens that I also have (and smaller than Fuji’s 23mm f2 that I don’t have). The focus ring is taut and fairly smooth – though there’s a bit more drag than I would like – but the aperture ring is also smooth; it doesn’t click at all. This means it’s hard to know exactly which aperture it’s set to without looking at the lens. Focusing with this lens is all visual, since the camera can’t get any data from it. I used focus peaking, at it was fast and accurate; I’ve used manual lenses in the past, and I often use manual focusing with the lenses I have. However, at open apertures, this lens truly sucks. Here’s a shot of my garden at f1.8. The vignetting is horrible, and there’s a bluish tinge to everything. If I stop it down to f16, the vignetting goes away, the bluish tinge fades, but the lens isn’t very sharp (I’ve reduced the size of the photo here a lot, but the sharpness was poor in the original unscaled photo). You might want to have a cheap lens that duplicates the toy camera look of a Holga or other cheap camera, and in that case, this lens will suit you fine. But this lens is essentially unusable at open apertures, meaning that to get good colors and even lighting you need to be at f11 or 16; it’s not worth having a lens that limited. Yes, you save money compared to, say, the Fujifilm 23mm f2 lens, but the quality of Fuji’s lenses is as good as it gets for this type of glass. (Amazon.com, Amazon UK) Plus you get autofocus, weather resistance, and better overall build quality. -Có ngàm dành cho Sony E-mount,Fuji FX Mount,Canon EOS-M Mount,và Panasonic Olympus M43. -Tiêu cự: 25mm -Khẩu độ: F1.8-f16 -Khoảng cách lấy nét gần nhất: 0.18m -Số lá khẩu: 12 -Cấu tạo ống kính: 7 thấu kính thuộc 5 nhóm -Kích thước filter: 46mm DISCLAIMER: Below are my own thoughts and opinions on the 7artisans 25mm f/1.8 lens. I paid for the lens with my own money and I am not sponsored or associated with 7artisans. By no means are my views scientific and should be taken with a grain of salt. Whether you agree or disagree, please let me know in the comments below! Camera: Fujifilm X-E2 Lens: 7artisans 25mm f/1.8 Focal length: 37.5mm (in 35mm equivalent) Focusing: full manual The Good: My first impressions of handling the 25mm is that the lens is solid and well-built. The lens body is entirely metal with a metal lens hood that screws in securely. I opted for the silver version and it came with a matching silver bayonet lens hood (purchased via Aliexpress). The lens itself is tiny and makes my X-E2 even less intrusive when shooting on the street. The aperture ring is clickless and well-dampened making it difficult to accidentally bump your F stop. The focus ring is heavily-dampened and has a healthy throw making it easy to fine focus on fine details. In comparison, my Voigtlander 35mm Nokton Classic lens has an overly sensitive focus ring with a short throw, making fine adjustments difficult to nail. As a bonus, the minimal focus distance is as close as about 1 inch, making this capable of being a pseudo macro lens. The Bad: Quality control at the China-made factory is not the best. Be sure to thoroughly inspect your lens after receiving it as you may need to exchange your lens for another copy. When looking at the front element, my lens has a spot under the glass off to the side which may be something that dripped onto the glass during production. Luckily, it does not affect image quality and cannot be seen in images. Other consumers have complained of poor construction or improperly calibrated lenses, so be sure to thoroughly put your copy through it’s paces when you receive it. The rear design of the lens has a bad design and rear lens caps do not securely lock and stay on, often falling off when in your camera bag. At first I thought it was due to the 7artisans’ rear lens cap design, but oem Fuji caps do not securely stay on either. Image Quality: I tried searching but was unable to find anyone else able to verify, but I suspect 7artisans may have copied the Zeiss Biogon formula when creating this lens. To my eye, images share a familiar bokeh and could pass as a cousin to the Zeiss. When shooting wide open, the lens has a touch of vignetting and adds some nice character. The culmination of these different details helps the lens create some moody images with some soul. This lens is definitely NOT for the pixel peeper. You can still get tack sharp images in the center of the frame or if you focus stack multiple images in post, but don’t expect this ultra budget lens to compete with more expensive brands. When shooting on either end of the aperture range, expect some softness due to diffraction. Conclusion: Buy it. Simple as that. When I originally bought this lens, it only cost me 45$ shipped from Aliexpress. As of Feb 2019, prices have increased to 70$-80$ from most online vendors, mostly due to receiving loads of positive reviews from early adopters who were willing to try out 7artisans’ lenses. Even at this increased price, i’d still highly recommend this lens and argue that it’s still a good deal. If you’re looking for a superbly compact lens for your small mirrorless body, this is the perfect companion. My Fuji X-E2 with 7artisans 25mm f/1.8 lens mounted makes for a great stealthy street photography setup. See below for some street photography samples (click to enlarge). |
