What matters

Both cameras share the entry-level Canon RF-mount APS-C baseline: an approximately 24 MP sensor, the same battery system, one UHS-I SD card slot, and no sensor-shift in-body stabilization. The R50 is worth stepping up to for operation and capture capability, not for a different lens mount or a fundamentally larger sensor.

Key differences

  • EOS R100 uses DIGIC 8, offers Dual Pixel autofocus for stills, shoots up to 6.5 fps, and has a fixed 3-inch non-touch screen. EOS R50 uses DIGIC X and Dual Pixel CMOS AF II with people, animal, and vehicle detection, reaches 12 fps with electronic first curtain or 15 fps electronically, and adds a 3-inch 1.62-million-dot vari-angle touchscreen. That makes moving family members, pets, and sports easier to follow and capture on the R50.
  • For video, EOS R100 records 4K24 with a central crop and contrast-detection autofocus. EOS R50 records uncropped 4K30 oversampled from 6K with Dual Pixel autofocus. The R50's articulating touchscreen and less constrained video mode make it the clear choice for self-recording, hybrid shooting, and unusual camera angles.
  • Canon US marked both body pages as no longer available, so those pages do not provide a current official-direct transaction price. A used or leftover R100 becomes a value choice only after its lower price survives checks for condition, shutter history, bundle contents, return policy, and warranty; otherwise the R50's operational advantages are the better buy.

Who it is for

  • Choose EOS R50 if you regularly photograph moving people, pets, or sports, or if you need an articulating touchscreen and capable autofocus for video.
  • Choose EOS R100 only when a verified used or leftover body is materially cheaper, your subjects are mostly static, and its fixed screen, slower burst, and limited video mode will not obstruct your work.

Watch-outs

  • Do not infer a current official-direct price for either body from the cited Canon pages. Compare seller condition, shutter history, included lens and accessories, warranty, repair state, and return rights.
  • A cheap body can become an expensive kit if the lens bundle is poor or you need spare batteries and replacements. Those ownership costs can erase the apparent saving on an R100.
  • Buy neither if sensor-shift in-body stabilization or current official-direct body stock is a requirement.
