Canon EOS R8vsRicoh GR IV: Full-FramevsPocket
These two are both compact mirrorless cameras at very different sizes, and they share a 3-inch screen and USB-C charging. What decides it is reach versus pocketability: the Canon EOS R8 takes interchangeable RF lenses and shoots 4K, while the Ricoh GR IV is a fixed-lens APS-C camera built to disappear in a jacket pocket.

Sensor and low light
The Canon EOS R8 uses a full-frame sensor, which is the biggest single reason to pay for it. A larger sensor gathers more light, so low-light shots are cleaner and background blur is easier to get. The Ricoh GR IV's APS-C chip is smaller, and its higher pixel count of 25.74 MP is a rounding-error advantage rather than a real one.
Ricoh counters with stabilization. The GR IV is rated at 6 stops of in-body stabilization, with 4 stops toward the frame edges, while the R8 has none. That means handheld shots in dim interiors are far easier to keep sharp on the Ricoh, which offsets some of the sensor gap for still subjects.
Video
This is not close. The R8 records 4K up to 60 fps in 10-bit with Canon Log, H.264 and HEVC. The Ricoh GR IV tops out at 1080p and H.264 with no log profile published. If video is any part of the plan, the Canon is the only realistic option here.
The R8 also gives you a headphone jack and a micro HDMI port for monitoring and clean output. The Ricoh has neither, and its video leaves over USB-C as DisplayPort rather than HDMI. Vloggers and hybrid shooters should treat the GR IV as a stills camera.
Speed and autofocus
Canon's subject detection covers people, animals, birds, cars, trains, planes and motorcycles. The Ricoh GR IV only detects human faces and eyes. For sports, wildlife or kids running around, that difference shows up in how many frames actually land in focus.
Burst rate leans the same way. The R8 does 40 fps electronically and 6 fps with the mechanical shutter; the Ricoh's only published figure is 4 fps with no shutter type stated. The R8 also pre-bursts for 0.5 seconds, which the GR IV does not list.
Handling and battery
The R8 has a 2.36M-dot electronic viewfinder, a fully articulated 3-inch screen at 1.62M dots, and dust and drip resistance. The Ricoh GR IV has no viewfinder, a fixed screen, and no published weather sealing. Shooting in bright sun or at odd angles is much easier on the Canon.
Ricoh wins on size and stamina in the pocket. At 262 g and 32.7 mm deep it slides into a jeans pocket, and the R8 is 461 g before you add a lens. The trade is battery: the Canon is rated at 370 shots versus 250, so the Ricoh needs a spare on a long day.
Which is best for sports?
The Canon EOS R8, by a wide margin. Faster burst, subject recognition for vehicles and animals, and pre-burst capture all matter when the subject moves. A fixed 28mm-equivalent lens on the Ricoh also can't reach out to a sideline or a bird.
If your sports shooting is casual street-level action, the Ricoh's pocket size is still useful, but it will miss frames the R8 catches. Buy accordingly.
The Verdict
Buy the Canon EOS R8 if you want full-frame image quality, 4K video, subject-tracking autofocus and a viewfinder, and you accept carrying a bigger body and lenses. Buy the Ricoh GR IV if the camera has to live in your pocket and you shoot mostly stills in good or handheld-stabilized light. The R8 is the better tool. The GR IV is the one you'll actually have with you.

FAQ
Does the Canon EOS R8 have image stabilization?
No. The R8 body has 0 stops of in-body stabilization, so you rely on lens IS or faster shutter speeds. The Ricoh GR IV offers 6 stops at the frame centre and 4 stops at the edges.
Can the Ricoh GR IV change lenses?
No. It has a fixed lens, while the Canon EOS R8 uses the Canon RF mount and accepts interchangeable lenses. That makes the R8 far more flexible over time, at the cost of size.
Which has better battery life?
The Canon EOS R8, rated at 370 shots versus 250 for the Ricoh GR IV. Both charge over USB-C, and the Ricoh also has 53 GB of internal memory alongside its single microSD slot.
Is the Ricoh GR IV weather sealed?
Ricoh does not publish a weather-sealing rating for the GR IV. The Canon EOS R8 is described as dust and drip resistant, though neither carries a published IP rating in the available specs.
