The Leica Viewing Magnifier M 1.25x is a small and practical accessory for select Leica M rangefinder cameras, from the M (Typ 240)-series and earlier. By enlarging the viewfinder image by twenty-five percent, it facilitates image composition when using lenses with focal lengths of 50mm and upwards. At the same time, it also improves focusing accuracy by expanding the effective measuring base. Especially useful for the M line since the different viewfinder models offer different magnification ratios.
Made of black anodized aluminium, the viewing magnifier is screwed into the camera eyepiece. It also has a thread for correction lenses to compensate for vision defects. An optional Thread Adapter is also available for use on the M10-series of cameras.
The small accessory is secured with a chain and connected to the camera eyelet with spring catches. The viewing magnifier can be kept in its leather case with snap fastener and attached to the camera strap when not in use. The magnifier is thereby protected and is easily accessible whenever required.
