Abstract
Official abstract text for this publication.
An image capturing apparatus includes: a photographing optical system; an image capturing element; and a viewfinder device, in which the viewfinder device includes at least one variable magnification lens that may be inserted on and removed from an optical path of the viewfinder device, and a drive mechanism configured to drive the variable magnification lens, in which the image capturing apparatus further includes: a variable magnification lens control unit configured to supply a drive signal to the drive mechanism so as to control the insertion and removal of the variable magnification lens on and from the optical path, and perform a high-speed control to move the variable magnification lens through a maximum moving distance for a first time, and a low-speed control to move the variable magnification lens through the maximum moving distance for a second time that is longer than the first time.
First claim
Opening claim text (preview).
What is claimed is: 1. An image capturing apparatus comprising: a photographing optical system; an image capturing element configured to capture an image through the photographing optical system; and a viewfinder device configured to be capable of observing a photographic subject through an optical system that is different from the photographing optical system, wherein the viewfinder device includes at least one variable magnification lens that may be inserted on and removed…
