MTF charts for Canon's RF lenses?

[PatFig]

Hi all, does anyone know where can I view MTF charts for Canon's RF lenses? 

Thank you!

I found a few databases for EF lenses and a good article from Rudy Winston, but nothing complete for RF lenses.

Anyone else?

You can also try Canon Sales.  I'm sure they have these.

IMHO, the only thing MTF charts tell you is how good the lens is at taking fancy pictures of charts. Tells you little to nothing about how well a lens preforms in the real world situations. They do give the lab guys something to do and talk about. 🤔

click on image of lens, e.g. https://cweb.canon.jp/eos/rf/lineup/rf16-f28/

Then click on "specification" if your browser translates the page to English, e.g. https://cweb.canon.jp/eos/rf/lineup/rf16-f28/spec.html

If that was true, no one would bother. MTF charts provide, (from a number of samples), a comprehensive idea of how a lens will eliminate CA, or minimize vignetting, or limit any number of things IN real world use. Maybe you don't notice them because you aren't focused on them. But other people do. Someone like me has to focus on them because we do more technical photography like macro or astro.

Is that site in Japan still working?  I was looking for an MTF chart for the RF14f/1.4L VCM, but FFox comes back with "cannot reach site" for any of the links you provided?  Thanks!

There have been massive SYN flood distributed denial of service attacks recenty. I likely by a large organization such as a government. I suggest keep trying.
