A substantial article follows on the Canon F-1 new model, addressing battery specifications, AV gain calibration, meter positioning, speed-indicator disc adjustment, and other operational parameters essential to field service work. Throughout, the publication delivers high-quality technical illustrations, step-by-step disassembly photography, component layouts, and functional schematics that guide technicians through adjustment and maintenance procedures with precise reference values. Additional coverage addresses Hasselblad equipment servicing. The issue rounds out with advertising rates and contact information for specialized technical services in the photography repair sector. Intended as a reference document for technicians performing preventive maintenance, troubleshooting, and component-level repair on professional camera systems.
SPT - Vivitar Series1 35 85mm f28 VariFocal guide
Comprehensive service manual for the Vivitar Series 1 35-85mm f/2.8 Varifocal zoom lens, offering detailed repair and maintenance procedures for optical and mechanical adjustments. This workshop guide covers essential tuning of spacer positions and optical element placement to restore peak lens performance. You'll find precise focus adjustment instructions for both 35mm and 85mm focal lengths, field curvature correction, element centering, and diaphragm aperture calibration. The manual walks through focus ring operation, zoom ring brake tensioning, diaphragm rotation alignment, and helicoid timing setup. Step-by-step disassembly sections include annotated photographs that document helicoid assembly and internal component layouts, making complex teardown straightforward. A troubleshooting section addresses the most common failure points: helicoid impact damage, guide screw and roller shear breakage, and optical misalignment. Practical repair tips cover partial-disassembly approaches for localized fixes without full teardown. Technical drawings and detailed component illustrations clarify adjustment procedures and part relationships throughout, making this manual an essential reference for technicians working on this lens.
SPT - Vivitar Series1 70 210 Guide
Comprehensive technical service manual for the Vivitar Series 1 Macro Zoom 70-210 lens, covering maintenance, adjustment, and repair procedures. The guide establishes essential calibration values and adjustment positions for focus settings across the 70 mm and 210 mm focal lengths, minimum aperture sizing, and alternative aperture configurations. Detailed procedures address cleaning and lubrication of the focus assembly and lens groups, with secure disassembly protocols protecting optical component integrity. Instructions provide step-by-step access to the diaphragm system, zoom mechanism, and focus components. A dedicated section walks through helicoid disassembly with specific alignment reference points and thread positioning markers to ensure proper reassembly. The troubleshooting guide identifies common issues resolvable without full lens disassembly, and highlights frequently damaged areas such as the zoom lens barrel and impact-related damage patterns. Important technical notes document seized threaded parts and design variations between early and recent production styles, enabling effective repair work while maintaining optical centering and performance specifications.
SPT - Yashica FR1 FR2
Comprehensive service and repair manual for the Yashica FR1 and FR2 35mm cameras with focal-plane shutter. This technical workshop manual provides detailed maintenance procedures, adjustment specifications, and troubleshooting methods essential for servicing these automated camera models.
