Canon R10 vs Sony a6400

Two of the most cross-shopped APS-C cameras under a grand. Canon's fast burst and deep grip, or Sony's benchmark autofocus and huge lens system?

By Stephen V.Last updated How we pick

These two sit right next to each other for anyone buying their first “proper” mirrorless camera. Both use 24-megapixel APS-C sensors, both have a viewfinder, and neither has in-body stabilization. They’re genuinely close on image quality — so the decision comes down to handling, autofocus, and which lens system you want to live in.

The Canon R10 leans toward speed: faster burst shooting and a deeper, more comfortable grip. The Sony a6400 leans toward focus and flexibility: its Real-time Eye AF is still a benchmark, it’s weather-sealed, and the E-mount has the widest, most affordable lens selection of any APS-C system. Here is how they compare.

#1Best for burst and grip

Canon EOS R10

The enthusiast step above the R50: faster burst shooting, a deeper grip and a second control dial, plus the same trustworthy Dual Pixel autofocus. If you shoot action, sports or kids and want APS-C without going Sony, this is Canon's sweet spot.

Strengths

  • Fast mechanical and electronic burst shooting
  • Twin dials and a proper grip for one-handed control
  • Reliable subject tracking for moving targets

Trade-offs

  • 4K60 is cropped; no in-body stabilization
  • RF-S lens lineup is still limited

#2Best autofocus and lenses

Sony a6400

A durable all-rounder that has aged well thanks to genuinely sticky autofocus and a proper viewfinder. It is the pick if you want stills as much as video and don't need in-body stabilization — the eye AF still tracks a moving subject better than a lot of newer, cheaper bodies.

Strengths

  • Real-time Eye AF that still holds up years later
  • Built-in electronic viewfinder for shooting in bright sun
  • Weather-sealed against dust and moisture

Trade-offs

  • No in-body stabilization
  • Menus are the older, denser Sony layout

Which should you buy?

Buy the Canon R10 ifyou shoot action and value how a camera feels in the hand. Its faster burst is better for sports, kids and pets, the deeper grip suits longer lenses and one-handed shooting, and Canon’s guided, friendly interface is a gentle place to learn. It’s a featured pick in our beginner mirrorless guide for exactly those reasons.

Buy the Sony a6400 ifautofocus, weather sealing and lenses matter most. Its Real-time Eye AF locks onto eyes and holds moving subjects with a reliability the R10 can’t quite match, the weather sealing helps outdoors, and the E-mount’s enormous third-party lens support (Sigma, Tamron and more) means more choice and often lower prices as you grow. It also appears in our hybrid camera guide.

For most people it comes down to two questions: do you want the faster, grippier action camera (R10), or the stickier autofocus and the bigger, cheaper lens ecosystem (a6400)? Either way, spend your next money on a lens rather than a second body — our portrait lens guide is the best place to start.

Frequently asked questions

Which has better autofocus, the R10 or the a6400?

For sheer stickiness on moving subjects, the Sony a6400's Real-time Eye AF is the benchmark and edges ahead. Canon's Dual Pixel CMOS AF II on the R10 is excellent and very beginner-friendly, and its faster burst helps for action. Both are among the best in class; the a6400 has the slight autofocus edge, the R10 the burst-speed edge.

Which has more and cheaper lenses?

The Sony a6400, thanks to the E-mount's huge third-party support from Sigma, Tamron and others. That usually means more choice and lower prices as you build a kit. Canon's RF mount for APS-C (RF-S) is newer and its native lens lineup is smaller, though full-frame RF lenses also fit.

Is either camera weather-sealed?

Only the Sony a6400, which has dust and moisture resistance that helps outdoors and in poor weather. The Canon R10 is not weather-sealed, so it needs a bit more care in rain or dust. If you shoot outdoors often, that's a real point in the a6400's favor.

Which is better for video?

They're close. The a6400 shoots oversampled 4K30 with excellent autofocus; the R10 shoots oversampled 4K30 plus 4K60 (with a crop). Neither has in-body stabilization, so for handheld video you'll want a stabilized lens or a gimbal. The R10's 4K60 option and the a6400's autofocus are the main differentiators.
