Which should you buy?
Enthusiast Photography, Travel & Street — X-T30 III (2025): 40MP resolution and flagship-level subject detection in the most affordable X-T body — the best value Fujifilm camera ever made.
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.
