During zooming, a distance between every adjacent lens units varies. During focusing from an infinite distance to a minimum object distance, the lens unit Ln and the lens unit Lm move toward the object side. The focal length FLm of the lens unit Lm and the focal length FLm2 of the lens unit Lm2 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 having the same","description":"A zoom lens includes, in order from an object side to an image side, a lens unit Ln having the highest negative refractive power of all the following lens units, a lens unit Lm2 having positive refrac","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9715094","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.
