Canon Explains Why RF Lenses Are Better Than EF

By David J. Crewe on June 19th 2019

In a recent article, Pye discussed that if he could only have one lens, it would be the Canon 28-70 f/2L [Linked Here] lens for its characteristics and optical quality. As professional photographers, we always strive to capture and produce the cleanest, sharpest, and best quality of image possible. Thus as we grow we seek out and acquire the best quality optical equipment possible for our respective brands of cameras. As the years go by, the technology changes and improves allowing us to create  better and better images. Well I recently found a video from Canon that shows the technology behind Pye’s  lens choice and the new RF Mount system and figured I should share all those details with you.

In the video below, Canon explains why the RF mount system really is such a huge deal and why it’s a massive improvement over the previous generation EF mount systems in the older DSLR models. (This improvement also applies to the Nikon Z mount system.)

But what makes these lenses so outstanding? This video introduces the innovative features of RF lenses that open up new possibilities in photographic expression.

As you can see and hear in the video, Canon says what makes the difference is the distance between the rear lens element and the sensor. This shorter distance allows them to focus the light more evenly and accurately across the entire sensor. With the older EF system the rear element is so far away from the sensor that lenses need to be larger and heavier to compensate for the problem.

If you thought that the RF 28-70mm F2 was impressive, what has me excited about this whole new system evolving, is just thinking about the patented, (but still only rumored) RF 14-21mm f1.4 wide angle zoom. As a landscape fan and timelapser, being able to shoot so clean and sharp at such a wide angle…well…I mean…I can’t even find the words to express my excitement and I don’t even shoot on Canon Systems!

What do you think about this and the Nikon Z systems? Is it enough for you to consider making the leap to Mirrorless? Are you already using the new systems? We’d love to hear your thoughts in the comments below.
