Price and rating as shown on Amazon when we collected them. Both change.
The Canon RF 85mm F2 Macro IS STM is a fixed 85mm prime for Canon's RF mount, listed at £518.50 and rated 4.4 out of 5 from 357 ratings. It sits third in this guide, and it is the only lens in the list whose listing quotes a magnification figure for close-up work: 0.5x macro, with a minimum focusing distance of 35 cm.
That one figure is doing more work than the rest of the spec table. The table files Maximum Aperture as "2 Millimetres" — an f-number is a ratio, not a length, so the field tells a buyer nothing — and it lists a Zoom Ratio of 1:1 on a lens it also calls a Prime. Meanwhile the bullet copy and the description both settle on nine diaphragm blades and a 9-blade iris. Everything on this page comes from the Amazon listing, not from any test of our own.
