Canon EOS R5

Pros

• 45MP resolution provides excellent 'cropability' for wildlife and birds
• Seamless adaptation of EF lenses with no performance loss
• Significant autofocus improvement over older DSLR systems, especially eye tracking
• High durability, with reports of bodies exceeding 450,000 shutter cycles
• Strong professional performance in diverse environments, including studio and underwater

Cons

• Noticeably heavy and bulky, particularly when paired with a battery grip or large RF lenses
• Autofocus tracking and speed are now viewed as slightly inferior to newer R-series flagships
• Lacks built-in GPS
• Limited electronic shutter customization compared to more recent models

Caveats

• Sharpness gains from the 45MP sensor are highly dependent on proper technique and lighting
• Used prices have remained surprisingly high even after the release of the Mark II
• Some users report a hit in low-light performance compared to lower-resolution full-frame sensors

Best for

• Wildlife and bird photographers needing extra reach via cropping
• Professional photographers with a large investment in EF-mount glass
• Studio and commercial photographers requiring high megapixel counts

Avoid if

• You prioritize a lightweight, compact kit for personal or travel use
• You require the absolute latest in 'sticky' autofocus tracking for fast-moving sports
• You need integrated GPS for location tagging
