Nikon Z 30vsSony a6700: Which APS-C Camera?

The Sony a6700 carries a 26 MP sensor against the Z 30's 20.9 MP, so the Sony gives you more room to crop and still print large. That extra resolution is the main reason to pay more if you shoot stills and crop often.

The Z 30 reaches a higher native ISO ceiling — 51,200 versus 32,000 on the Sony. Settings above that ceiling are expanded on both, so the Nikon's advantage is real but narrow. In practice the Sony's in-body stabilization, rated at 5 stops, matters more for handheld low-light work than the ISO gap does.

This is the widest gap between the two. The Sony a6700 shoots 4K at up to 120 fps, though that top rate uses a crop; full-width 4K tops out at 60 fps. The Nikon Z 30 stops at 30 fps in 4K. If you want slow motion or smoother motion at normal speed, the Sony is the only real option here.

The Sony also records 10-bit video with HEVC codec support and a log profile rated at 14 stops of dynamic range. The Z 30 records H.264 only, and Nikon does not publish bit depth or log support for it. For anyone grading footage or protecting highlights, that difference is decisive.

Both cameras fire at 11 fps with the mechanical shutter, so stills burst speed is a tie. The difference is what the autofocus can lock onto. The Sony a6700 detects humans, animals, birds, insects, cars, trains and airplanes. Nikon does not publish subject detection for the Z 30.

For wildlife, pets or motorsport, that subject library is a practical advantage — the camera finds and holds the eye or the vehicle while you frame. For portraits and everyday shooting, the Z 30's contrast and phase-detect system still gets the job done.

The Z 30 has no electronic viewfinder at all. You compose on the 3-inch rear screen, which is fully articulated on both cameras. That is fine for vlogging and casual shooting at arm's length, but it is a real limitation in bright sun and for eye-level shooting with long lenses.

The Sony a6700 has a 2.36 M dot viewfinder with 0.7x magnification. If you shoot handheld with your eye to the camera — sports, wildlife, portraits outdoors — the Sony is the more comfortable tool. If you shoot from the screen, the Nikon's lack of a finder costs you nothing.

The Sony a6700 is rated for 570 shots on a charge; the Nikon Z 30 is rated for 330, and that figure assumes the EN-EL25 battery — the count differs with the EN-EL25a. Nearly double the battery life means fewer spares and less mid-shoot swapping on the Sony.

The Z 30 is the smaller and lighter body: 405 g versus 493 g, and it is wider and taller but noticeably shallower. Carried all day or mounted on a gimbal, that 88 g difference is the Nikon's clearest win.

The Sony a6700 has a headphone port; Nikon does not publish one for the Z 30. If you monitor audio while recording, that alone can decide the choice. The Z 30 uses a Mini HDMI connector, which is more robust than the Sony's Micro HDMI — fewer bent or broken plugs on set.

Both support USB charging and power delivery, though the Nikon needs an optional EH-7P or EH-8P adapter for it. Both have a single card slot and neither publishes weather sealing or a minimum operating temperature above 0 °C.
