Canon hasn't missed that the EF version of the 100mm f/2.8 macro lens has been popular as a portrait lens for some time and asked Kahran and Regis Bethencourt of CreativeSoul Photography to take the new RF model for a spin. Together, they show the insane image quality this new optic can deliver.
Oliver Wright, a professional macro photographer, shows how the Spherical Aberration Control Ring -- also known as the Bokeh Control Ring -- on the new RF 100mm f/2.8L Macro IS USM works in a 5.5-minute video published in conjunction with Canon Europe.
When you look through your viewfinder and things seem a little bit blurry or lacking definition, it's probably because you are using an “el cheapo” lens. So you read reviews and buy a much more expensive lens, and what do you do next?
Canon just released this 3.5-minute video that explains how lenses work. We learn about focal points, spherical aberration, chromatic aberration, and how multiple lens elements are used together for aberration correction.
