Abstract: An optical image capturing system includes, along the optical axis in order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens. At least one lens among the first to the sixth lenses has positive refractive force. The seventh lens can have negative refractive force. The lenses in the optical image capturing system which have refractive power include the first to the seventh lenses. The optical image capturing system can increase aperture value and improve the imaging quality for use in compact cameras.

Abstract: An optical element driving mechanism is provided, including a movable part, a fixed part, a driving assembly, and a first supporting assembly. The movable part is used for connecting an optical element. The movable part is movable relative to the fixed part. The driving assembly is used for driving the movable part to move relative to the fixed part. The movable part is movable relative to the fixed part through the support of the first supporting assembly. The movable part includes a movable part setting surface, and the movable part setting surface corresponds to the optical element.

Abstract: The present invention relates to optical imaging systems which are able to provide increased depth of field to microscope devices, motion-picture cameras, and still photographic cameras, while also reducing or elimination breathing while the focus of the device is adjusted. Optical systems described herein are also able to be used with standard film and digital sensor formats, and are able to be attached to, or integrated with, photographic and motion-picture cameras, including currently existing cameras.
