I noticed something interesting regarding the field of view between the RF 16mm and RF 14-35mm on an R5 at a distance of only a few feet. As one would expect when using Canon DPP to process images, the FOV of the 14-35 (set at 14) is noticeably wider than the RF16. However, if Lightroom or DXO is used to process the images (with their respective lens corrections), there is very little difference in FOV between the two lenses at a distance of only a few feet.

Not sure how much those results might be impacted at longer focusing distances. Nor do I have a 15-35mm to test for comparison.

I actually did get hold of some raw files from an R5 with 14-35 and used converted them using both DxO PureRAW and Lightroom (using the provided profiles).

My observations were:

* The original image from the camera is wider than 14 mm
* DxO provides a wider image than Lightroom - probably wider than DPP as well and wider than 14 mm?
* DxO does a much better job at processing the image - the sharpness (especially in the corners) are MUCH better

The images can be seen here:

I have not actually tried to convert the raw file using DPP - but maybe I will test it.

Edit: I now converted the image in DPP and see that it is the most narrow of DxO/LR/DPP. Lightroom is wider, but DxO is even wider again. See link to fredmiranda for updated post there.
