Canon's most affordable RF-mount mirrorless, bare-bones for the most budget-conscious buyer.
The Canon EOS R100 was released in June 2023 as Canon's entry-level APS-C RF-S mirrorless body, positioned below the EOS R50 with a lower price and reduced feature set. Dual Pixel CMOS AF II with 143 AF zones provides subject tracking for stills and video. The 4K recording mode applies a significant additional crop beyond APS-C and is limited to 24fps — a deliberate specification limitation relative to the R50, which provides 4K/30fps. 1080p at up to 60fps is available without additional crop.
The 24.1MP APS-C CMOS sensor incorporates Dual Pixel CMOS AF II. The 143-zone DPAF II provides subject tracking including Eye Detection. Burst shooting runs at 6.5fps with One-Shot AF and 3.5fps with Servo AF. 4K video records at 24fps with a significant additional crop; 1080p records at up to 60fps. No in-body image stabilisation. Battery life approximately 340 shots via EVF using the LP-E17, body weight approximately 356g with battery and card, single SD/SDHC/SDXC slot.
The R100's practical strengths are DPAF II subject tracking and the compact, affordable RF-S body for stills photography. For video, the 4K limitation to 24fps-only with significant crop makes the R100 primarily a 1080p camera in practice — the R50 is the better choice if 4K is a regular requirement. The 3.5fps Servo AF burst rate is low for moving subjects; the R100 is aimed at casual stills users and beginners rather than sports or action photographers. The LP-E17's 340-shot CIPA rating requires a spare battery for extended sessions.
On the used market the R100 is the most affordable RF-S mirrorless body. Condition checks: DPAF II operation in live view, LP-E17 battery health, and screen for marks. The EOS R50 provides 4K/30fps with lower crop and higher burst rate at a modest premium. Canon has no AF motor in body — RF-S and RF lenses autofocus normally; EF/EF-S lenses require the Mount Adapter EF-EOS R. Compatible with all Canon RF and RF-S mount lenses.
