>>4072611Yes, but I'd like to add that the differences between the sensors show up exactly in editing. I've never shot with a newer sensor than the Canon 6D in the Canon 6D, RP category, but I can assure you, if you compare the Canon 6D with the 5D4, that the latter is much better at suppressing banding and noise, which doesn't make much difference unprocessed, but makes corrections and editing at high ISO much easier, maybe since even small differences in noise have a big effect. These differences are even noticeable with different sensor formats. Having both cameras at the base ISO, the Canon M5 shows much more latitude when moving sliders around in Lightroom compared to the 6D, despite being APS-C. The 6D only catches up here at higher ISO values.
But yes, we agree with each other, with the Canon 6D (me), and RP (you), it's advisable to expose as bright as possible to not push exposure and shadows further in post, it's advisable to maximize shutter speed and aperture to be brighter but have less ISO.
Again (and this is the reason for my post) OP is in a backlight situation at sunset, which without fill light requires underexposure and (if it's not for silhouettes) hard shadow push, with DR already limited due to the dark environment, due to the high ISO. This can put a strain on processing RP raws, on 6D raws this would assured be the case, on the 5D4 it would not be such a stark extend.
That being said, I use the Canon 6D in worse environments and only for moments in editing (on bloopers) regret not having used the better gear in this regard.
