Canon EOS R8vsNikon Z 30: Which Camera to Buy

The Canon EOS R8 uses a 24.2 MP full-frame sensor; the Nikon Z 30 uses a 20.9 MP APS-C sensor, which Nikon calls DX. A larger sensor gathers more light at the same aperture and framing, so the Canon holds detail better in dim rooms and at dusk, and gives shallower depth of field for portraits. The pixel gap is small and rarely visible in normal prints.

The Canon also reaches a higher native ISO ceiling, which matters when you would rather raise sensitivity than slow the shutter. The Nikon's ceiling is lower, and settings above it are expanded rather than native. For available-light work indoors or after sunset, the Canon is the easier camera to shoot handheld.

Both cameras cap out at 4K resolution, but the Canon EOS R8 records 4K at up to 60 fps and the Nikon Z 30 stops at 30 fps. That extra headroom lets the Canon halve motion in-camera, so panning shots and moving subjects stay smooth without slowing footage in post. The Canon also records in HEVC alongside H.264 and captures 10-bit color with a log profile, which gives more room to grade.

The Nikon records in H.264 and does not publish bit depth or log support. If you shoot casual clips for social media, the Nikon's 4K 30p is entirely usable. If you deliver graded footage or want slow motion straight from the camera, the Canon is the clear pick.

The Canon EOS R8 has a 2.36 M-dot electronic viewfinder, so you can hold the camera to your eye, brace it against your face, and frame in bright sun where an LCD washes out. The Nikon Z 30 has no viewfinder at all, which means every shot is composed on the rear screen.

That design keeps the Nikon small, but it changes how you shoot. Outdoors in daylight you will shade the screen or guess at framing, and holding the camera away from your body is less stable at slow shutter speeds. The Canon's rear screen is also the sharper of the two, which helps when checking focus on the Nikon only.

The Nikon Z 30 fires faster on the mechanical shutter, and that advantage is worth having for bursts of moving subjects. The Canon EOS R8 counters with a much faster electronic burst and a pre-burst mode that keeps a short buffer of frames from before you press the button, which is genuinely useful for timing a jump or a serve.

The bigger gap is subject detection. The Canon recognizes people, animals, birds, cars, trains, planes, and motorcycles, so it tracks and holds focus on its own. The Nikon publishes no equivalent list. For sports, wildlife, or chasing a toddler, the Canon does more of the work.

The Nikon Z 30 is the smaller and lighter camera on every dimension, and the difference is large enough to feel on a strap all day. It is the better choice if the camera needs to disappear into a bag or you shoot one-handed for long stretches. The Canon is bulkier but adds dust and drip resistance, which the Nikon does not publish.

Battery life tilts the other way. The Canon is rated for more shots per charge, though the Nikon's figure is measured with the EN-EL25 battery and changes with the EN-EL25a. Both charge over USB, but the Nikon needs an optional adapter for in-camera charging and power.

The Canon uses the RF mount and the Nikon uses the Z mount, so lens choice is settled by whichever system you already own or plan to build. Neither mount takes the other's glass. The Canon's full-frame sensor also means RF lenses designed for full frame will render at their intended field of view, while the Nikon's DX sensor crops them.

The Nikon offers a full-size HDMI port, which is sturdier for a monitor or recorder cable than the Canon's micro connector. The Canon includes a headphone port for monitoring audio; the Nikon does not publish one. If you record to an external device, that HDMI difference is worth weighing.
