Hengyijia 25mm F1.8 (Black) HD.MC Manual Lens for SONY E-mount NEX ILCE Camera

Product Information

Here's a few samples from the Skerryvore concert I shot last night. Only PP was my standard NR and sharpening I use on all my concert photos, and some cropping. The 7artisans 25/1.8 looks to me like a rebranded Zonlai/Discover/Hengyijia 25/1.8. The other brands also offer a 35/1.8. Both the 25mm and 35mm use the same lens housing, and I suspect the distances marked on the focus scale would be decently accurate on the 35mm, but they didn't bother to print a separate focus scale for the 25mm. I have a Wesley 24/1.8, which seems to have identical optics to the 25/1.8, but with a different housing. The focus distances are actually not bad, though the center mark is off by a little bit. Easy to adjust for it, though. I placed a piece of gaffer tape to mark where the accurate distance should be read. in extremely sunny weather it seems to be sometimes difficult to see what’s in focus and what’s not. I had this problem particularly on snow — snow produced a lot of highlights in the viewfinder which is again similar to focus peaking highlights. I mis-focused several images because of this. Split image manual focus assist might be better in this use case. This lens is fully manual — there’s no auto focus (and no electronics) in this lens. Because there’s no electronic connection between camera and the lens, camera can’t actually detect that lens has been placed into the mount. To be able to shoot pictures with fully manual lens, you need to configure your Fuji camera to “shoot without lens” in the menu.

When I set my camera to ISO-Auto, the first option on the list, which takes 3 shots and combines them, and with f/1.8 I can really get some good night shots. This puts the reviewed lens at the higher end of the price range, but it can justify that with its impeccable performance and the fine quality of the resulting images. In the last few weeks, we covered a couple of new Chinese Fujifilm X mount lenses here on FujiRumors, such as the brand new 7Artisans 60mm F2.8 1:1 Macro and the Kamlan 50mm f/1.1 MK II. As the Alpha 7 range has been a game-changer for cameras, so I suspect Samyang is becoming a game-changer for lenses. Apochromatic lenses have special lens elements (aspheric, extra-low dispersion etc) to minimize the problem, hence they usually cost more.|One possible explanation is the heavy vignetting at larger apertures which makes metering choose slower shutter speed than expected. Glass

Flare is also very well suppressed, no doubt thanks to good lens barrel design as well as the well established Super EBC coating technology.Maybe I am a hard reviewer. Just being honest. I didn't just judge wide open. I posted just as many shots stopped down. And I just follow-up with with a stop down comparison all the way to F16. One of the main issue I have is the corners don't get much better until F8, which makes F2-F7 not very useful. I noticed that aperture ring is quite off. I did a very simple non-scientific test — I set the camera on ISO 200, lens on f/2 and tuned the exposition compensation so that shutter speed falls on 1/100s. Then I switched lens to f/4, f/8 and f/16 to see what’s the shutter speed, expecting that it should go down by the factor of 4 (since I’m testing 2 stop differences). Results (sorry for the table look): | Aperture | f/2 | f/4 | f/8 | f/16 The only complaint I have is the focus scale, which is sufficiently at odds with the reality through the EVF to make scale/zone focus a non-starter. The barrel contains feet and metre distance engravings, progressing (in feet) from 0.6, 1, 2, 5, 16 and infinity markings. Subjects at approximately 5ft - pin sharp at f1.8 though the EVF - showed closer to the 16 ft than 5 ft markings, and the void between the two makes hyperfocal shooting a gamble. It's possible, but you'd have to work out your own sweet spot and most users will confirm distance through the viewfinder. I assume the discrepancy is the result of the same lens being produced for a variety of sensor formats.

It's just a re-housed CCTV lens (like the 35/1.8 and 50/1.8) rather than a dedicated APS-C lens design like many of the later ones.I also think lenses like this mark a new era in affordable, quality manual focus lenses with native mirrorless camera lens mounts. A great era we live in. I wondered for some time if it could be some optical effect and not real bubble. But since Hengyijia copy arrived and it has nothing like that, it must be real. Lens hood To help with focusing, I use a DIY Sugru to mold a focusing tab on the focusing ring, it helps me quite a bit. Approximately 90% of those images, on those albums, are made using 7Artisans 25mm f1.8 lens with Fuji XE-1camera. I started thinking about whether or not my expectations are much, much lower for this little lens than yours might be.
