My, what a pleasure I had yesterday shooting for the first time with my friend's R5.

I can't wait to recieve the images from him.
He also has 5D Mark IV which he's going to sell and replace it with R6 as a back-up for R5. As a former 5D Mark IV owner, I absolutely loved the 5D, but the R5 makes the 5D Mark IV (and my EOS R also) to look old and outdated.

It's impressive how accurate the R5 af is on a moving person whyle shooting at f1.2. The af stayed on the subject eye so easily in backlit situations or with some obstacles in front...
Also, the feel of the camera and the viewfinder experience is way better than expected. I don't like or need the resolution, but given that I shoot a lot for stock agencies these days and I also plan to do video for stock, I may take a closer look at R5 instead of R6, if it will become available for rent.

It's selling so well here so the store that usually has a new pro camera for rent in less than a month from the release in order to attract buyers, doesn't have one available for rent.

The optical diagram/section is interesting. they've basically kept the same barrel size but moved the optics forward due to flange distance sacrificing hood effect in the process.
Not a big difference in real life between these 2 lenses. The RF version looks better and it's a tad sharper in the center of the frame. It's a good inexpensive lens and I think this was the goal with it, to be a price attraction for the ones who want an additional lens to the kit lens.
