I haven't ever used either of these but my general rule of thumb is if I already have a certain lens range and f-stop in one mount then there is low priority to replace in a different mount is low priority unless the lens I own is hot garbage/obsolete.

Using this rule it seems like going from the EF to RF version is a lateral move. From what I've read about the RF version, the extra 2mm wide may not matter because of the unsuitable distortion at that point. So unless you really need those extra 2mm and your RF collection desires are otherwise complete I'd pass and save or use the money for something missing or with a higher need of replacement in your kit.

The lens does capture a full 14mm angle of view after correction. Without correction it's about 13mm. You don't give up anything.

I don’t think that is true, there is stretching and cropping done to the image.

why they don’t do vignette free lenses are to save money on less used glass.

the same goes for other RF llenses.

RF 24-105 STM @ 24mm after correction is not as wide as the 24mm on RF 24-105 F4L.

It is true 14mm after correction, and Canon does specify its AOV on their website = 114 degrees = AOV of 14mm lens. If you can prove its AOV spec. is wrong, you can sue Canon for false advertisement, and easily get 10000+ dollars of settlement fee.

I have both RF14-35 and RF24-105 f4L lens. I can tell you for sure both lens have and need distortion corrections. 24-105's distortion at 24mm has much less than 14-35 at 14mm At 24mm f4 14-35 is actually better than 24-105. It is not surprising to see a more expensive 2.5x zoom lens to perform better than a cheaper 4x zoom lens (very obvious if you compare their images before correction). Anyway, if you want a good image, you need to turn distortion correction on for both lens.

I did not say anything about 14-35 vs 24-105f4L

i said 24-105 STM vs 24-105 F4L .
