Camera Craftsman - Rolleiflex SL35

This issue of Camera Craftsman features an in-depth examination of the Rolleiflex SL35, Rollei's distinguished single-lens reflex camera celebrated for its elegant engineering and innovative design. Written by Lawrence C. Lyells, the comprehensive article explores the camera's lightweight construction, weighing under 28 ounces with its standard 50mm f/1.8 lens.

The primary focus is the electrically cross-coupled CdS exposure meter system that allows light readings through the lens at stopped-down aperture. Detailed explanations cover the dual-roller focal-plane shutter mechanism, its unique design elements, and operational procedures for precision exposure control.

A significant portion addresses exposure meter adjustment, calibration, and optical alignment procedures. The article thoroughly documents the three trim potentiometers for fine-tuning meter response, the focal plane mirror adjustments, and the focusing screen modifications—all achievable without requiring lens removal.

Extensive technical photography and circuit diagrams illustrate internal mechanisms including the mirror cocking and release system, the opening curtain brake lever assembly, closing curtain control gears, main wind shaft cam operations, and film transport sprocket systems. Readers will discover Rollei's thoughtful engineering touches, such as the spring-loaded ball detent for wind lever positioning and the convenient adjustment points accessible from the camera base.

This issue is essential reference material for technicians servicing advanced SLR cameras and enthusiasts seeking deep understanding of precision camera mechanics.
