I've been looking at comparisons between different brands and that R5 sensor looks great in terms of PDR.

I wouldn't put too much stock in a high DR that is achieved by raw-cooking the deep shadows.

yikes, please explain how raw cooking (to presumably reduce noise) can increase DR

By "DR" I meant the calculated DR.

To be fair, one could measure what it would be if that cooking wasn't there, by using higher raw levels that aren't cooked and extrapolate towards black, but even if you get the potential DR, any cooking will give unexpected deep shadow qualities.

I remember when you gave me great advise not to use any sharpening of high iso 7d2 images - instead just go with a razor sharp lens instead - and the 7d2 was only 5/8 of a stop from the 5d3 - vs the classic 1 and 1/3 stop -- impressively close for its time

I was using LR at the time which really hurt the image with sharpening

today I use the AI of the class leading DXO PL for my NR

so yes indeed I'd rather use class leading NR software on uncooked files rather than having Canon cook them with inferior capability - ie, their DPP software NR sucks which is an indicator they lack the best NR methods to use in cooking raw

I guess for them marketing is marketing - but in the end noise and sharpness are not mutually exclusive  - and nobody is trying to develop comparators for the sharpness output between bodies so Canon is under the radar when they cook raw to get the charts to look better
