The latest M-series Leica now has an EVF. This product is a godsend, allowing you to equip an EVF to a camera body that originally only offered focusing via the rangefinder's split-image system or by looking at the monitor. You simply attach it to the hot shoe. Since the angle is adjustable, it can also be used like a waist-level finder. An EVF is extremely convenient when you need precise focusing at wide apertures with fast lenses. This allows for quick snapshots and portrait photography!
