The first lens unit includes a first lens sub unit not moving for focusing, and a second lens sub unit moving during the focusing. The first lens sub unit includes a negative lens and a positive lens. A focal length of the first lens unit, a distance on an optical axis from a lens surface closest to an image side of the first lens sub unit to a rear principal point position of the first lens sub unit, and a focal length of the zoom lens at a telephoto end are appropriately set."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Zoom lens and image pickup apparatus including the same","description":"Provided is a zoom lens including, in order from an object side: a first lens unit not moving for zooming; a second lens unit moving during the zooming; at least one lens unit moving during the zoomin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9739986","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.
