Canon EOS R100 with RF-S 18-45mm: What to Know
The strategic argument for this kit is the mount. Canon's RF system is the one it is actively developing, so lenses bought now carry forward, which is not true of the EF-S lenses in the Rebel T7 kit further down this page. For a beginner spending money on glass for the first time, that matters more than any single specification.
The autofocus is the camera's real strength. Canon's Dual Pixel CMOS AF with 143 autofocus zones is derived from the same technology as its much more expensive bodies, and it tracks people reliably, which is what a beginner camera is mostly pointed at. The sensor is APS-C at 24 megapixels, with the DIGIC 8 processor and 6.5 frames per second burst shooting.
The lens included is the Canon RF-S 18-45mm f/4.5-6.3 IS STM, which Canon describes as a general-purpose zoom. It has image stabilisation and a stepping motor for quiet video focus. Note the RF-S designation: it is an APS-C lens, so if you later move to a full-frame EOS R body it will trigger automatic crop mode.
The video specification is where you pay for the price, and the listing is honest about it: 4K at 24p with a crop, plus Full HD at 60p. A cropped 4K means the camera uses only part of the sensor, so your 18mm lens behaves as a narrower one in 4K, which is awkward for vlogging. The Nikon Z50 II at the top of this page does uncropped 4K 60p and is the better video choice.
One listing inconsistency: the headline and one bullet say 24.1 megapixels while another says 24.2. The difference is immaterial but it is a reminder to read these listings carefully.
