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.
Dslr Enthusiasts & Outdoor Photographers — Pentax K-3 Mark III (2021): The finest APS-C DSLR ever made — class-leading weather sealing, optical viewfinder, 5-axis IBIS, and extraordinary build for photographers committed to DSLR.
Compact Travel & Content Creation — A7C (2020): The A7C proves full-frame doesn't have to be bulky. Excellent battery life, reliable Eye AF and a vari-angle screen in a pocketable body is a compelling combination for travel and content creators. The A7C II improved on it, but the original remains a strong value buy.
