A combined handheld stack photography telescopic lens assembly

Abstract

The utility model discloses a combined handheld stack photography telescopic lens assembly, through modularization design realizes many specifications adaptation, is constituted by first mirror drum subassembly, second mirror drum subassembly, aperture structure subassembly and telescopic mirror group. The mirror drum subassembly can be combined through the screw thread, and the built-in lens forms different mirror groups, and the aperture assembly is exposed uniformly in cooperation, and the telescopic mirror group contains sliding cylinder, telescopic spring and telescopic mirror drum, and the spring provides telescopic power, and the damping structure (rubber part or damping grease) controls telescopic speed, and the limit design ensures the movement stability. When using, manual press telescopic mirror drum focuses foreground, and slowly releases and makes the focal point with mirror drum extension smooth and moves to the background, and the photograph group of composition, exposure is consistent is obtained, and is adapted to the later stack synthesis. It does not need external device, and it is portable, convenient and stable, reduces the cost while guaranteeing the picture quality, breaks through the traditional macro stack photography limitation.
