| comment: | This is a small metal manual lens with a native E-mount that is available under several brand names. It has been heavily marketed by 7Artisans recently. I purchased the silver Discover version for $75 shipped in 2016 from an eBay seller based in California. I purchased the black Neewer branded version in late 2018. These look and function very similarly. The Neewer version came with a brown vinyl storage bag. "MADE IN CHINA" The original Zonlai version of this lens had the aperture ring at the front of the lens and was listed for $130. Zonlai also sold a similar looking 35 F1.8 lens, and now has a 22 F1.8. Meike sells a MK 25 F1.8 that has a larger filter thread diameter. I have a C-mount 25 F1.8 that has a more complex optical formula. I've also tried another C-mount 25 "F1.8" mini lens very strong field curvature. It feels nicer than the Kaxinda/Neewer/Meike primes. There is no roughness in either the focus or aperture throws. Both are nicely damped. The focus is the opposite direction to Minolta and Canon lenses. It focuses much closer than the Meike, but not as close as the Green-ring C-mount lens. The center sharpness is good wide-open, but the corners are a bit dark and mushy. It has a similar amount of barrel distortion as the 16-50PZ, 18-55 SAM, and Minolta AF 24mm F2.8. It seems to let in more light than the printed aperture numbers report--brighter than other F1.7 and F1.8 primes. The aperture scale is off more than a full stop comparing both exposure and visual aperture measure. F/4 on the scale seems to be closer to f/2.8--f/16 on the scale is more like f/8. I redid the charts using equivalent exposures to adjust the aperture instead of relying on the printed aperture scale. The focus distance scale is also very inaccurate. The printing on these lenses is just decorative. Test charts and sample images here. |
