GearScore™ Verdict — Which should you buy?

Photographers Who Want To Strip Back Every Distraction — BF (2025): The most radical camera in years — no dials, no buttons, just a flat aluminium body and total creative minimalism.

Portrait, Landscape & Studio Photography — A7R II (2015): The A7R II transformed the A7R series — adding IBIS, 4K video, BSI sensor tech, and phase-detect AF in one generation. A landmark Sony camera.
