GearScore™ Verdict — Which should you buy?
Professional Sports & High-Speed Burst Photography — COBALT 128GB UHS-II SD Card: If your camera has a UHS-II slot, the COBALT is one of the best cards to put in it. ProGrade is a brand started by former SanDisk and Lexar engineers — the quality and consistency match the pedigree. Faster file transfers and better burst clearance justify the price premium for professionals.
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.
