What We Like
+Industry-leading autofocus with cross-type sensors and eye control for reliable subject tracking
+Exceptional high-speed shooting at 40fps sustained for 7.5 seconds with large buffer capacity

Worth Knowing
−24MP resolution is lower than competitors' flagship models (45-50MP), limiting large print/crop flexibility
−Noticeably heavier and bulkier than predecessor R3, causing fatigue during extended handheld shooting
−Reduced LCD resolution (2.1M dots vs R3) despite flagship pricing
−AF performance limitations with dark-skinned subjects in low light conditions remains unresolved from R3
