Which should you buy?
Architecture, Landscape & Astrophotography — RF 15-35mm f/2.8L IS USM (2019): The best wide-angle zoom Canon has ever made — optically superb, stabilised, and L-series built.
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
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
