This series evaluates the Canon RF 28-70mm f/2L at 28mm at far distance on the 30-megapixel Canon EOS R on a planar subject.
This subject is perhaps the most demanding test scene I use, in that the extremely fine detail along planar (flat) subject are merciless to lenses showing field curvature and/or weak in the outer zones.
Canon RF 28-70mm f/2L Aperture Series @ 28mm: Mosaic (Canon EOS R)
Includes images up to full camera resolution from f/2 through f/11.
There is a great deal to like about the about $2999 Canon RF 28-70mm f/2L. It is a must-have for the Canon mirrorless shooter.
