A camera body determines control on the interchangeable lens by referring to the driving method information obtained from the interchangeable lens to generate a control signal. The lens controller of the interchangeable lens controls the drive unit according to the driving method instructed by the control signal received from the camera body, when autofocus control is performed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Camera body, and camera system","description":"An interchangeable lens includes a drive unit that drives a focus lens back and forth along an optical axis, a storage unit that stores driving method information indicating a driving method for autof","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488050","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
