20mp on the 7D ii’s 6 year old sensor will perform much worse than a 17mp version of the new R5 sensor especially with a low pass or no AA filter.
The 7D ii performance in low light is pretty terrible for instance and I’m sure the R5 in crop mode would be vastly superior and I’d love to buy an R5 but it’s very expensive
If canon priced the R7 at the same or slightly less than the R6 and with similar features I’d buy it for sure.
Yeah, it's absolutely awful at ISO 3200, f/2.8, 1/800, isn't it?




But the age and performance of the 2014 7D Mark II is beside the point.
The existing 32MP APS-C sensor in the 90D and M6 Mark II is better than the 7D Mark II in similar lighting. Presumably a 32MP version of the roughly 80MP sensor expected in the predicted R5s would be even better than that.
This would be a more significant improvement over the 7D Mark II than a 17.8MP APS-C version of the FF 45MP sensor found in the R5.
Many of us who want a 7D Mark II replacement would be perfectly happy with an R7 that uses the existing 32MP sensor found in the 90D/M6 Mark II combined with the DiG!C X processing pipeline and an APS-C version of the 500,000 cycle shutter in the R5 (or even the 300,000 rated shutter of the R6) in a magnesium alloy body with weather sealing comparable to the R5.
Just for comparative purposes, the 2014 $1,799 7D Mark II had a 200,000 cycle rated shutter at the same time the 2012 $3,499 5D Mark III and the 2016 $3,499 5D Mark IV had shutter ratings of 150,000.
