About

14mm — Wide. Landscape drama, cinematic space. 35mm — Street. The classic reportage frame, natural and honest. 50mm — Standard. The human-eye view, no distortion. 85mm — Portrait. Compressed space and beautiful subject separation. HOW IT WORKS - A clean 2:3 viewfinder with Leica-style frame lines, so you compose deliberately. - Every shot is a real capture from a real lens — never a digital crop faked from one photo. - A focal length key is printed on every export: 14 WIDE · 35 STREET · 50 STANDARD · 85 PORTRAIT. SHARE OR STUDY - Story — a 9:16 contact sheet for Stories. - Feed — a clean 2:3 grid. - Save the composed frame to your photo library for reference or class material. Quartet works best on iPhone models with multiple rear cameras (iPhone 12 and later recommended) for true optical framing across all four focal lengths. Made by 2B Studio.
