Is the 7artisans af 85mm f 1 8 good for portraits?

Yes, the 7Artisans AF 85mm f/1.8 is a sensible portrait lens. It's an 85mm, the classic focal length for full-frame portraits, with autofocus and an f/1.8 aperture for soft backgrounds. It has no stabilisation, so keep shutter speeds up. It's made for Sony E, Nikon Z and L-Mount, and on APS-C it frames like about 128mm, which is a bit long for most portraits. Check the 7Artisans AF 85mm f/1.8 page for your camera.

If you want something lighter, the Samyang AF 85mm f/1.8 P FE weighs about 270 grams. For a faster classic option on full frame, look at the Nikon AF-S 85mm f/1.4G. For the wider picture on lens choice, see portraits.
