The F15-300mm zoom system is composed of visible light zoom lens, control circuit board and power supply circuit board. The visible light zoom lens includes CCD, optical lens, diaphragm, potentiometer, micro-dc motor, CAM and other structural parts. 3 Optical lens design 3.1 Zoom lens system is an optical system in which the focal length changes within a certain range and the image plane remains fixed. In general, the relative aperture is constant during zoom.For imaging system, continuous zoom optical system is the best way to solve the problem of large field search and small field resolution. The ratio of the two ultimate focal lengths in the zoom range, namely the ratio of the long focal length to the short focal length, is called magnification ratio, also known as multiplier. In consideration of the secondary spectrum requirements, the plan of the small relative aperture of the long focal length is adopted (that is, the relative aperture also changes during the zoom process). 3.2 The optical system USES a continuous zoom lens with a focal length of 15mm~300mm.

Contrary to popular belief, a super telephoto does not have to be a massive lens, proven here with the Nikon AF-S NIKKOR 500mm f/5.6E PF ED VR. Taking exceptionally long reach and giving it a hand-holdable form factor, this 500mm prime utilizes a unique Phase Fresnel element to greatly reduce the size and weight compared to previous versions of the focal length. This PF element, along with three extra-low dispersion elements, also helps to virtually eliminate color fringing and chromatic aberrations in order to achieve a high degree of clarity, sharpness, and color fidelity. Complementing this advanced optical design, individual elements also feature both Nano Crystal and Super Integrated Coatings to suppress flare and ghosting, as well as a protective fluorine coating to guard the optical system from dust and moisture.
Spanning a long, versatile zoom range, the AF-S NIKKOR 200-500mm f/5.6E ED VR Lens from Nikon is a telephoto zoom characterized by a constant f/5.6 maximum aperture for consistent performance throughout the zoom range. The optical design incorporates three extra-low dispersion glass elements to reduce chromatic aberrations and distortions for increased sharpness and color accuracy. Also contributing to improved image quality, a Super Integrated Coating has been applied to lens elements to lessen flare and ghosting for improved contrast and clarity. A Silent Wave Motor AF system produces fast, near-silent focusing performance that suits both stills shooting and movie recording, which can instantly be manually overridden by simply turning the manual focus ring. Further contributing to photographing in fast-paced situations and difficult lighting, VR (Vibration Reduction) image stabilization compensates for the effects of camera shake by up to 4.5 shutter speed stops. Additionally, an electromagnetic aperture mechanism is integrated into the lens design to provide greater exposure control stability that is especially beneficial when working with faster continuous shooting rates.
