Description — Leica M4
The Leica M4 is a fully mechanical 35mm rangefinder camera that operates without any battery, using the Leica M lens mount and a 24x36mm full-frame film format. It supports film stocks ranging from ISO 4 to ISO 1300, giving photographers flexibility across a broad range of shooting conditions and emulsions. Focusing is entirely manual via a rangefinder patch system — no autofocus, no selectable points, no tracking of any kind.
The reverse Galilean optical viewfinder offers 0.72x magnification and brightline framelines for clean, accurate framing. For flash, the M4 provides a PC sync socket with X-sync at 1/50s alongside a cold shoe (no electrical contacts). The body is built from a brass top plate and metal chassis with vulcanite covering, coming in at 550g and 138 x 77 x 34mm — compact and solidly constructed.
There is no image stabilization, no weather sealing, and no digital connectivity of any kind. This is a stripped-down, discipline-first tool for film photographers.
