Fujifilm X100VIvs Leica SL3vs A6400
Which should you buy?
Street, Travel & Everyday — Fujifilm X100VI (2024): The best fixed-lens camera ever made — 40MP, 7-stop IBIS, film simulations, and a design icon. Wildly oversubscribed for good reason.
Professional & Luxury Hybrid Shooters — Leica SL3 (2024): Leica's most capable mirrorless — 60MP, 30fps burst, 8K ProRes, and 7.5-stop IBIS with L-mount's growing lens ecosystem.
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
