How to pick the right Sony
Start with sensor size. Most people want APS-C— the a6400, ZV-E10 and the step-up a6700 all use it — because it delivers excellent photos and clean 4K in a smaller, cheaper body, and it takes the same E-mount lenses as the full-frame line. Full-frame (the a7 IV and a7 III) gathers more light and gives shallower background blur, but the bodies and lenses are bigger, heavier and far more expensive. Buy full-frame only if low-light performance or paid work genuinely calls for it; our full-frame vs APS-C guide walks through the trade in plain terms.
Then decide whether you need a viewfinder. The a6400 has one, which matters the moment you shoot stills outdoors where a rear screen washes out. The ZV bodies drop the viewfinder deliberately — they’re built to be shot off a flip-out screen while you talk to the lens, with creator features like a background-blur button and a better built-in mic. If you mostly film yourself, that trade is the right one; if you shoot as many photos as videos, get the viewfinder.
The last question is the lens, because it changes your images more than the body ever will. Sony’s E-mount has the widest, most affordable lens selection of any system, with strong third-party support from Sigma and Tamron — which is a real reason to buy Sony in the first place. Whatever body you choose, budget for one good fast prime early: our Sony APS-C lens guide and portrait lens guide are the best next step, and a microphone will do more for your video than any sensor upgrade.
A note on the models we left off
Sony’s lineup runs deep, and a few bodies just missed the cut here. The a6700is Sony’s flagship APS-C camera — it adds in-body stabilization and the AI autofocus from the full-frame line — and it’s the one to grow into if YouTube is a job rather than a hobby; it leads our cameras for YouTube guide. The newer ZV-E10 II adds uncropped 4K60 over the original ZV-E10, which we cover in our ZV-E10 vs ZV-E10 II comparison. We feature bodies here that show a live, verified price so every recommendation comes with a reachable buy button; where a model is between stock, we point you to the guide that covers it rather than list a stale number.
