Last week, Canon rehoused a couple of its old EF lenses into RF cases, but also released something brand new. A macro lens that wasn’t just an old design with an EF to RF adapter bolted on the end, but a whole new design. That lens is the Canon RF 100mm f/2.8L Macro IS USM and it brings with it a new and very unique feature – Spherical Aberration Control.
It’s a ring just behind the focus ring that lets you adjust how the out of focus areas of the scene are rendered within your shot. But what does that mean in the real world? How does it make them look? Well, this video from Canon Europe answers that with some examples from pro macro photographer, Oliver Wright, who’s been using it with the Canon EOS R5.
