Canon RF 15-35mm f/2.8L Aperture Series: Big Laurel at Bend in Alpine Creek (Canon EOS R5)

This series from f/2.8 to f/11 with the Canon RF 15-35mm f/2.8L IS USM is presented with two series: one series shot where initially planned, and another shot with focus ~10 feet closer. The two series show how easy it can be to prove that the same lens is better/worse than itself, and thus why it is so hard to compare different lenses, or even different samples of the same lens model.

I had been attempting to match focus on this scene against the Canon RF 14-35mm f/4L, and in spite of trying on two different days, it proved impossible to get a satisfactory match. Part of this is the distortion differences, part is field curvature differences. It’s really hard to compare the two on a scene like this.
