GearScore™ Verdict — Which should you buy?
Wedding, Events & Documentary Photography — HD D FA 24-70mm f/2.8 ED SDM WR (2015): The professional zoom for Pentax DSLR shooters — weather-sealed to the same standard as the K-3 Mark III, with a constant f/2.8 across the full range.
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.
