Canon and Nikon users continue to rejoice in the belief that their respective lens mounts are superior when compared to Sony, but the latter just fired off another shot during their a6400 presentation, asserting that even f/.63 is theoretically possible. Even setting aside the vast catalogue of native lenses, E mount enjoys a singular advantage over the competition in that it is compatible across the entire lineup, providing an upgrade path from Sony’s entry level a6*** APS-C sensor cameras on up through their full frame bodies and top-of-the-line cinema cameras. Sadly, Canon’s 50mm f/1.2L RF lens is only compatible with one camera body – the middling 30 megapixel EOS R! And Canon’s top product-planning executive said in a recent interview that their next EOS R camera will not be the 50 megapixel dual card slot beast reviewers have been anticipating, but an entry level body. hehe Meaning that for the time being, GM lenses have the upper hand on the 42 megapixel a7R III.

Slides from Sony presentation:

Canon’s 50mm f/1.2L RF has received lots of praise for sure, but it is nearly 200 grams heavier than Sony’s Planar, almost $1,000 more dear, and according to Lens Rentals, is practically unrepairable. Oh, and it suffers from vignetting. Just how much? Around four stops wide open! Meaning it is actually slower than Sony’s Planar, which has a highly respectable showing of T1.6. As Canon’s ultra-fast glass doesn’t benefit from stabilization, photographers will get consistently sharper images with Sony’s Steady Shot cameras, especially those shooting in available light. Sony also has the edge where eye autofocus is concerned – Canon’s EOS R only operates in S-AF, whereas the A7 III and a7r III work in both single and continuous AF.

Let’s face it. Most Sony shooters want smaller, lighter, less expensive lenses, not glass that only brain surgeons can afford. That is why lenses like the Tamron 28-75mm zoom and Sony’s 24mm f/1.4 and 85mm f/1.8 have been immensely popular.
