Phase One Certified Pre-Owned Camera systems, digital backs, and lenses are held to a no-compromise philosophy. Each piece has gone through a rigorous 9-step certification process to ensure like-new medium format performance and quality. Everything is shipped in like-new condition, in new packaging, and with all accompanying accessories. Every Certified Pre-Owned component comes with a full 1-year warranty for your peace of mind.
1. FULL HARDWARE INSPECTION:
Each component is visually inspected, functionally inspected and preliminary tested for signs of wear or possible impairment. This inspection is internal, as well as external.
2. INTERNAL CLEAN-ROOM INSPECTION:
Under clinical conditions, each digital component is partially disassembled, cleaned, and reassembled as if it were a newly-fabricated component.
3. PRECISION FOCUS ADJUSTMENT:
Using microscopic measure, the digital sensor’s mounting plane is adjusted to ensure perfect factory focus and precision performance with the paired optics.
4. THOROUGH MECHANICAL TESTING:
All components undergo strict performance tests for all moving parts. Not only shutters and buttons, but also simple moving parts such as battery doors and CF card ejection buttons.
5. FINAL TEST OF ELECTRONICS:
Through integrated “stress tests” each electrical component is put through tests that ensure all integrated boards, processors and interfaces are working to new standards.
6. CALIBRATION AND FIRMWARE UPDATE:
In the final stages of the inspection and adjustment process, the entire system is calibrated and firmware is reinstalled, updated and verified.
7. TEST CAPTURES:
All ISOs, shutter speeds, apertures, and storage options are tested thoroughly in a studio setting, ensuring that all components are working in tandem and capturing images to meet the system specifications.
8. IMAGE QUALITY INSPECTION:
The test capture images are now inspected by certified image quality professionals, and compared to standard test images to ensure that the quality of the captures meets the standards of Phase One’s image quality.
9. QUALITY ASSURANCE CERTIFICATION:
Finally, the QA department performs additional independent, real world testing to ensure the camera works under demanding conditions without issue, and not just within a laboratory setting.
The Phase One Auto Extension Rings supports all Phase One, Schneider Kreuznach and Mamiya lenses. The electronic contact set ensures auto aperture functionality on lenses which features this. When attached via an Auto Extension Ring, all lenses operate as manual focus, and are limited to manual focus and focal plane shutter use. There is practically no light intensity degradation when using the extension rings, and there are no optical dispersion since no glass elements are added with the Auto Extension Rings.
