Canon EOS R, RF 28-70mm f/2L. (70mm, 1/400 sec, @f/2, ISO 400, Aperture priority, spot metering) Words cannot describe how impressed I am with this lens and the hit rate of the R's eye AF. This was taken through some brush between us in natural light (shade), with a small speedlight on a Manfrotto nano stand right behind her. I probably should have dialed down the power of the speedlight a little more, but I'm still learning and she is ecstatic about the photos. Just placed an order for the RF 85mm f/1.2L as I am very confident in Canon's new system. Best I have ever used.
