JUPITER - Jupiter 3 Clean and Lube 39mm CLA
Comprehensive clean and lubrication (CLA) guide for the Jupiter-3 39mm focus mount. This service manual provides detailed step-by-step instructions for complete disassembly, cleaning, and reassembly of this classic Soviet lens design. The document covers the five main mechanical components—the 39mm focus mount, inner helical, outer helical with inner sleeve, and focus ring—along with a complete parts breakdown. You'll find precise guidance on removing the optical module safely, disassembling the focus ring assembly, and thoroughly cleaning both helical sections to remove old, dried lubricant without damaging precision surfaces. The manual emphasizes critical techniques such as making scribe marks to preserve original component positions, carefully managing guide pins that control focus travel distance, and maintaining alignment throughout disassembly and reassembly. A dedicated section covers the outer helical assembly cleaning procedure, explaining how to keep the sleeve partially unscrewed to prevent misalignment, removing stubborn grease deposits with appropriate solvents and brushes, and applying fresh lubricating grease in correct quantities for smooth operation. The reassembly section details proper alignment using cam positioning and guide pin reference marks to restore correct rangefinder coupling and ensure optimal focus performance. Optional procedures for securing set screws with lacquer are also included. Essential reading for anyone performing maintenance on Jupiter-3 lenses, whether for hobby restoration or professional workshop use.
JUPITER - Jupiter 3 Contax Leica Conversion
Comprehensive technical manual for converting a Carl Zeiss Jena 5cm F1.5 Sonnar lens from Contax mount to Leica mount using a Jupiter-3 base. This service guide covers the complete optical modification workflow, including identification of critical components such as the optics module, focus mount, and adjustment shims. You'll find precise specifications for focusing distances, back focal length calculations, and the optical formulas needed to verify correct infinity focus after conversion. The repair instructions walk through separating the Zeiss optics module from its original Contax mount, adapting the Jupiter-3 variable stand-off ring where required, and properly seating the Zeiss optics into the Jupiter-3 focus mount assembly. Detailed procedures include tools needed (jeweler screwdrivers, aluminum stock, shim materials) and step-by-step instructions supported by photographic documentation. Contains direct comparison of focus travel characteristics between the original Zeiss configuration and the Leica calibrated setup, essential data for achieving correct optical performance. Invaluable for vintage camera enthusiasts, optical restoration technicians, and anyone undertaking precision lens conversion work.
JUPITER - Jupiter 3 Exploded
Comprehensive technical service manual presenting the complete internal structure of the JUPITER-3 lens through professional exploded diagrams designed for repair and maintenance work. This workshop guide provides a systematic breakdown of the entire optical assembly using high-resolution component photography and precise labeling. The manual begins with an overview of the three primary assemblies: the focus mount, main shim, and assembled optics module. The focus mount section details its sophisticated construction, including the 39mm thread mount, outer helical two-piece component with inner sleeve, and inner helical mechanism. The optics module section covers the complete breakdown of all constituent elements: the optical fixture, rear triplet, F-stop ring, two-piece aperture ring, coupling ring, aperture retaining ring configured as variable stand-off ring, and main shim. Each part is clearly identified through professional photography and precise labeling to enable accurate component identification and understanding of assembly relationships. Essential for optical technicians, camera repair professionals, and restoration enthusiasts requiring detailed knowledge of the JUPITER-3 internal architecture. The exploded view presentation directly facilitates disassembly, reassembly, and maintenance procedures while serving as authoritative reference and troubleshooting documentation for this classic lens.
JUPITER - Jupiter 3 Focal Length Adjustment
Comprehensive focal length adjustment guide for Jupiter-3 lenses manufactured before 1964. This technical service manual provides detailed procedures for adapting Jupiter-3 lenses with 39mm thread mount to achieve proper focus compatibility with Leica cameras, which are calibrated for a nominal focal length of 51.6mm rather than the standard 52.4mm. The guide explains the optical reasons behind infinity focus discrepancies and presents practical methodologies to resolve these issues through hands-on repair work. Coverage includes lens disassembly techniques, optical surface polishing, rear triplet element positioning, and main shim adjustment procedures, supported by specific optical formulas and technical illustrations for each step. The document also addresses focal length extension using standoff shims and provides iterative testing processes to verify corrections. Procedures are precise and require specialized tools including optical spanners and precision calipers. Additional topics cover identification of focus errors through F-stop analysis, glass element removal and reinstallation with proper protection of the aperture mechanism, and verification of image sharpness across the entire focus range. This reference work serves lens repair technicians, vintage camera enthusiasts, and anyone seeking to restore Jupiter-3 lens performance to original specifications.
