Lateral chromatic aberration is reasonably well controlled at f/1.4 but can be rather noticeable at narrower apertures. It’s rather worse than in most competing 85mm prime lenses. Distortion: 1.16

The Samyang FE 85mm lens boasts a weather-sealed design and there's a UMC Super multi-layer coating to help reduce flare and ghosting. It has a minimum focusing distance of 0.90m (2.95ft) and a maximum reproduction ratio of 0.11x. The build quality of the Sigma 85mm F1.4 DG DN Art is on par with the Sony GM and above the Samyang and Sony FE85mm F1.8 This fully manual lens is designed for the latest, high-tech Canon and Nikon mirrorless full-frame cameras. As well as being manual-focus, you can’t set the aperture from the camera body, so have to use the control ring on the lens itself. As with other manual lenses, the availability of a focus peaking display in the electronic viewfinders and rear screens of mirrorless cameras helps with accurate manual focusing, which can be critical considering that the depth of field can be tiny at 85mm with an aperture of f/1.4. IBIS (In Body Image Stabilization) is available in Nikon Z 6 and Z 7 cameras, if you enter the Non-CPU lens data in the Setup menu. It’s a fun lens to use, great value at the price, and delivers impressive image quality with beautiful bokeh. How we test lenses The photos straight out of the camera come with a warmer color and the bokeh that it creates has a uniqueness to it. I would like to see Samyang continue to refine the autofocus through firmware update (and I believe they will), but for the primary task of shooting portraits, this lens already does great. Eye AF works very well, and, while I don’t believe the autofocus to be fast enough for sports action, it is fast and quiet enough for event work, portraiture, and the kinds of general purpose shooting it was designed for. All in all, I think the AF85 does what it needs to, and I look forward to shooting with it more in the future. Sony shooters now have a reasonable F1.4 alternative to the excellent Sony FE 85mm F1.8 lens!With the lens set to its maximum aperture of f/1.4, there is significant light fall-off in the corners. Stopping-down to f/5.6 virtually eliminates this. There is no hyperfocal distance scale, or hard infinity stop, which is unusual for a lens like this, which uses no low dispersion glass in its optical design. Focusing is usefully internal and manual focusing is possible when the MF mode is set on the Sony camera body. Full-time manual focus override is also available if you choose the DMF focusing mode instead. There's no distance and/or depth of field scale available on this lens. The AF 85mm F1.4 FE’s optical design minimizes optical aberrations, while maximizing the image quality from corner to corner. Its detailed rendering results in exceptional image quality, even on the latest high-resolution full-frame cameras; and its bright maximum aperture means you can enjoy this excellent performance even when shooting indoors or in darker conditions.

The sharpness is very good wide open and excellent as of F2 and skin rendering is very good but maybe a bit too contrasty sometimes Samyang AF lenses: More recently, Samyang has brought autofocus prime lenses to the market. Most of these are designed for Sony mirrorless cameras, in full-frame FE-mount. There are currently nine in total, ranging from the AF 14mm f/2.8 FE to the AF 85mm f/1.4 FE, both of which are also available in Canon RF-mount editions. Samyang has additionally created 14mm and 85mm autofocus lenses in Canon EF and Nikon F mount options, but with a different design to the mirrorless lenses.I’m excited about this Samyang lens as I’ve always appreciated the performance and value of the previous versions of the lens, and now we’ve gotten a more compact size along with new features as a part of the formula. The new version is slimmer and lighter along with some other significant improvements:
