Z5vs A7 III
VS
Which should you buy?
Entry-Level Full-Frame & Dslr Switchers — Z5 (2020): The most affordable route into full-frame Z — dual card slots, IBIS, and a capable sensor at an accessible price.
All-Round Photography & Video — A7 III (2018): Still one of the best all-round cameras money can buy — particularly strong used. The A7 III proved that full-frame doesn't have to mean compromises, and nothing at this price point has meaningfully beaten it.
Who should buy what
Z5 (2020)
- DSLR photographers switching to full-frame mirrorless for the first time
- Enthusiasts who want full-frame image quality on a tighter budget
- Photographers stepping up from APS-C who don't need fast burst or 4K

A7 III (2018)
- Enthusiast photographers upgrading from APS-C for the first time
- Working photographers who need reliable AF and weather sealing
- Anyone who shoots in low light regularly
- Hybrid shooters needing both stills and video performance
