I've been enjoying Canon Rumors for years, but I finally joined the forum with this topic. I have an original R6, which is an amazing and capable camera. I've owned numerous Canon bodies of varying tiers prior to this. I'm very fortunate that my day job is that of a COO of a successful analytics company, so I don't need to pursue photography for pay. I do shoot a lot, all the same, and the pictures are used by my community. But in that context at the CAD $3k range of pricing I'm probably representative of a number of purchasers. I know many here are as well. I'm pretty optimistic about what the R6 III will bring, but my concerns about ISO (and related matters, such as dynamic range) is really head room. Like many people point out, there's probably not a lot of shooters using high ISO values exceeding 12k on a regular basis, but that 12k or lower is in the context of 102,400. If 12k is good when the ceiling is 102.4k, then how much worse might it be when the ceiling is 64k? Yeah, yeah, the R5 scaled down is equivalent, and so might the R6 III, but who buys one to scale down (not crop) from 45mp? So for us R6 shooters it feels like a potential downgrade -- at 3k+ for cost. It's a double-whammy too, because the new glass sacrifices light for speed and weight, so not only is Canon reducing the ISO but they're increasing the need for sensitivity for prosumers who aren't buying f/2 28-70 glass in bulk. I'm sure Canon does what it feels is appropriate, but whereas the R6 felt like a love letter to a patient community of well heeled but non-professional flag bearers then the R6 III, in terms of photography, feels more like a middle finger. Moreso if the price goes up. What did I actually want to see that would make me upgrade when the R6 II didn't? (And not knocking that edition, it's great for people who didn't buy an R6 but want that tier.) A better EVF. A better back screen. More programmable buttons. Maybe more resolution, if the ISO / DR is maintained. None of these are big ticket enhancements, but they'd get me to trade in and spend dollars on gear instead of on my wife or kids. Anyhow, I hope Canon monitors the comments from people like me for when they plan the R6 IV. By all means make an R6c, but for R6-pure go back to the original spirit please! Make it a love letter to the non-pros who want the essential character of pro gear--but not the expense of pro SLAs or high resolutions. But maybe it doesn't matter—maybe 2025 ISO 64k offers such improved quality that it's equivalent to 2015 ISO 102.4k. Given the R5, R5 II, and R6 II I doubt it. I'll keep saving for something that's interesting to me, and in the meantime hopefully the R6 III makes someone else's day.
