Sony FE 85mm f/1.8 Full-Frame Prime Lens

The Sony 85mm f/1.8 FE (model name 85 mm / F 1.8 FE, SEL85F18) is a fixed 85mm E-mount prime sold as full-frame, listed at £490.00 and sitting at number one in this guide on a 4.7 rating from 2,435 ratings. It is the cheapest lens in the running: the two Viltrox 85mm f/1.4 Pro lenses in the same list go for £569 each. The listing gives 9 diaphragm blades, a 67mm filter thread, a minimum focus distance of 0.8 m, no image stabilisation, and a 19-degree angle of view. Of the 100 ratings in the star breakdown shown on the listing, 86 are five-star, 10 are four-star and 4 sit at three stars or below.

Its own spec table repeats the problem this guide keeps running into: Maximum Aperture is filed as '1.8 Millimetres'. An f-number is a ratio of focal length to entrance pupil diameter, not a length, so that field tells a buyer nothing the bullet doesn't already say. The same table files a Zoom Ratio of 1:1 on a lens whose Lens Design field says Prime and whose focal length is fixed at 85 Millimetres — there is no zoom range to express as a ratio. Everything on this page is taken from the Amazon listing for this lens; we have not tested it ourselves.
