It is recommended to have a look at this article first to get an idea how this brightness graph works. The 7Artisans 35mm 1.4 M IF Wen has the same vignetting values within the margin of error. When we compare this to something like the Sony FE 35mm 1.4 GM the Sony is about 0.7 EV better at the maximum aperture but the same stopped down. The vignetting figures are average for a fast 35mm lens. The lens does not feature any electronic contacts to communicate with the camera. The problem: it also causes mechanical vignetting in the very corners (see Flare Resistance section). It increases the size of the lens noticeably, but indeed does help a bit with stray light. Pergear shipped the lens to me with what looks like a generic 43mm vented lens hood. Pergear 35mm 1.4 with 43mm screw in vented-hood The lens is a standard unit focus design and the front element does not rotate, so using a polarizer is a hassle free operation. What bothered me more: except for the focus and aperture ring the barrel is not structured, so removing and attaching the lens is as annoying as it is with a Zeiss Loxia lens without the PocketPano LensGrip or the Laowa 85mm 5.6 (to only name a few). Not the first lens with a typo on the casing, probably also not the last. There is also a typo here, as it says “MUTI COATED”. The lens seems to be made from metal, but – except for the distance scale markers – all the markings are only printed on. The aperture ring travels ~90° from f/1.4 to f/16. I found this rather confusing and it makes setting a desired aperture value without looking at the lens a bit complicated. The aperture ring is one of the most interesting I have seen so far, but why is that? It features half-stop(?) click-stops between f/1.4 and f/2.8 (no f/2.0 marking), one-third-of-a-stop click-stops between f/2.8 and f/4.0, full-stop click-stops between f/4.0 and f/8.0, nothing at f/11 and a last click-stop at f/16. The constructrion in itself is also very slightly wobbly, so there is a tiny bit of slack when changing the direction of rotation of the focus ring. The throw between 3.0 m and infinity is pretty short and I found setting precise focus at wider apertures rather fiddly in this distance range. The focus ring is also knurled, like those of some of the Voigtlander lenses. The focus ring has a nice albeit not perfectly even resistance and travels ~160° from the minimum focus distance (0.3 m) to infinity. This is the first Pergear lens I am having a look at and there are a lot of things to talk about here. The Pergear 35mm 1.4 was kindly provided free of charge by Pergear for reviewing purpose for a duration of 4 weeks. This lens can be ordered from | | | (affiliate links) and the price is $129 Disclosure Maximum Magnification: 1:6.2 (measured).Number of Aperture Blades: 10 (slightly rounded).Most of the chinese 35mm lenses I reviewed over the years came in M-mount and had to be adapted to E-mount (some have also been released later in E-mount with unchanged optics) but this Pergear 35mm 1.4 is an E-mount lens from the get go and with the diameter and position of the rear element I also doubt it would be compatible to M-mount. portrait distance 1.0 m (42mp Sony A7rII).
