When you're in the street and you have but a split second to capture the decisive moment, a rangefinder might be the tool you need. Fundamentally a different design from an SLR, looking through the viewfinder of a rangefinder lets you see beyond the framelines, allowing you anticipate elements coming into the frame so you can time your photo just right, and when you squeeze the shutter, there is no viewfinder blackout to disengage you from your subject.
Paying tribute to these trusty tools is the Classic Rangefinders 1-inch button set.
Featured cameras are the Leica M3, the Olympus XA, the Canon Canonet QL-17 GIII, and the Nikon S3.
