Samyang AF 85mm F1.4 Weather Sealed High Speed Auto Focus Lens for Canon EOS R Cameras - RF Mount (SYIO85AF-RF)

Product Information

Regardless of the camera format used and like most focal lengths, 85mm can be useful for landscape photography. With only a few exceptions, the f/1.4 max aperture made available by this lens is as wide as MILC lenses get. APS-C format cameras using lenses projecting a full-frame-sized image circle avoid most vignetting problems. Above: The rendering of a lens designed for portraiture is very important, so in my next test I’m going to compare the three lenses for bokeh blobs. For this test I positioned the camera at the closest distance that all three lenses could focus on the star ornament. Both the RF 85 1.2 and old EF 85 1.8 share a similar minimum distance of 85cm, so that’s what I’ve used here – oh and I manually focused the EF lens here to be sure. The RF 85mm f2 can get much closer, focusing down to 35cm and I’ll be showing much more of that in a moment.

Both the physical and optical construction of the AF 85mm f/1.4 RF make you wonder how Samyang can do it for the money. The value factor undoubtedly tops the list of reasons why you’d buy this lens, but obviously only because it doesn’t involve any significant compromises. The Canon lens uses 82mm filters vs. 77mm and features a focus limiter switch, control ring, better AF system, and better build quality. A relatively common lens aberration is axial (longitudinal, bokeh) CA, which causes non-coinciding focal planes of the various wavelengths of light. Wide open, it does have a fair amount of vignetting, but that is easily correctable in post. But quite honestly for certain types of images it actually looks great. Stop it down to 1.8 and its almost gone.The lens’s attractive bokeh, created through precise lens polishing, adds a great feeling of depth and space in your photographs. Also, its aperture mechanism comprises 9 precisely-controlled iris blades, providing natural, circular, out-of-focus highlights at all apertures. With this smooth bokeh, achieved through various optical technologies, you can create images full of character in your portrait or subject photography.

And just as you yourself explained, you are allowed to justify your setup. Why is it not valid for others to justify theirs to themselves however they want without getting the 3rd degree from you?

Mount an extension tube behind this lens to moderately decrease and increase the minimum focus distance and maximum magnification numbers.

As the aperture narrows, the entrance pupil size is reduced, and the mechanical vignetting absolves with the shapes becoming rounder — considerably rounder at only f/2.The Rokinon AF 85mm F1.4 Lens vs. Canon RF 85mm F1.2 L USM Lens comparison shows the Canon lens noticeably larger and weighing 2x as much. Moving farther out on the image circle, where light rays are refracted to a stronger angle than in the center, lenses typically show decreased sharpness. The "portrait photography" designation is a broad one that covers a wide variety of potential still and video uses ranging from moderately-tight headshots to full body portraits, with a wide variety of potential venues, including indoors and outdoors. Otherwise, I didn't pay strong attention to the details as there were other priorities at the time. as this is where the most significant difference in the magnification of wavelengths typically exists.
