The in-body stabilization keeps things steady for handheld shots, and autofocus mostly doesn’t let you down. You can use it for lots of things portraits, landscapes, events, even some studio stuff, though it’s a bit heavy to carry for long periods.Then there’s the Canon EOS R50. It’s smaller and lighter, so easier to lug around, especially for travel or street photography. The menus and controls are simpler, autofocus works pretty good, and video is okay for casual use.

Before diving into each camera’s detailed breakdown, here’s a direct spec-and-feature comparison to see how they stack up.

Specification

Sony ILCE-7M3K (A7 III + 28-70mm kit)

Canon EOS R50 + RF-S18-45mm kit

Sensor

Full-frame, 24.2 MP; larger pixels, superior low-light performance 

APS-C, 24.2 MP; smaller sensor, more crop, somewhat more noise in low light 

Autofocus

Sony’s hybrid AF, strong eye-AF, wide coverage; well proven in many lighting conditions

Canon Dual Pixel CMOS AF II; fast, reliable, especially for video / vlogging; very good tracking in its class 

Stabilization

In‐body image stabilization (5-axis) helps a lot with handheld, slower lenses 

No in-body IS; only lens IS if available; so more dependent on lens or tripod or steady hand 

Video

4K video (usually full-frame) with good detail; strong color, dynamic range; more flexibility in post-processing

4K30 video; Full HD up to 120 fps; lighter body helps for vlogging; but some limitations (crop / rolling shutter / stability)

Size / Weight / Handling

Heavier, stronger build; more grip; lens kit heavier; more fatigue if shot handheld long hours

Lighter overall, easier to carry; compact body makes it better for travel / vlogging / casual shooting

Price (kit)

Higher; more investment up front; accessories & lenses add up

Lower initial cost; more affordable lenses; less intimidating financially for many users
