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.

Prized for event, portraiture, and sports shooting, the Canon EF, Nikon F and Sigma SA mount Sigma 70-200mm f/2.8 DG OS HSM Sports Lens is a flexible telephoto zoom characterized by its bright and sophisticated design. The fast constant f/2.8 maximum aperture excels in difficult lighting conditions and also offers increased control over depth of field for isolating subjects. In regard to the optical layout, an impressive 10 low dispersion elements are used to greatly reduce chromatic aberrations and color fringing for improved clarity and color accuracy. A Super Multi-Layer Coating is also featured, and helps to suppress ghosting and flare when working in strong lighting conditions. Complementing the optics is an Intelligent OS system, which minimizes the appearance of camera shake for sharper results when shooting handheld. A Hyper Sonic Motor is also used to provide quick and quiet autofocus performance along with full-time manual focus override. The physical design of the lens also incorporates several seals to guard against dust and moisture, and a water- and oil-repellent coating has been applied to the exposed elements to prevent moisture, fingerprints, or smudges from sticking to the surface. Additionally, a fixed rotating tripod collar is featured, and has a removable Arca-type compatible foot for wide compatibility with different tripod or monopod heads.

Micro Lens (Ultra small lens) Because of the ultra-small size of this kind of lens (outer diameter 0.5mm-5mm, length: 1mm-20mm), micro lens or ultra-small lens often requires special processing technology, unique production know-how and special optical fixture, etc. Photonchina provides various sizes of micro lens with an array of applications including active devices, wavelength division multiplexer ( WDM) and fiber lasers (see C-lens, G-lens) in fiber communications, endoscopy for medical and industrial use, capsule endoscope, etc. Its new application fields are still expanding. A variety of optical glass or other materials, such as N-SF11, H-LAF76, Fused Silica and so on are available for customerâ??s design. H-LaF53, for instance, has often been used in endoscope lens or capsule lens production. The outer diameter of micro lens covers 0.5mm to 5.0mm with any radius of curvature that can be made. We have a wide range of lenses in shape: convex, concave, biconvex, meniscus etc. Photonchina can provide unique rod-shaped glued lens by combining special gluing technics and edging skill. This rod lens has excellent eccentricity and clear aperture index. From design, manufacturing to optical coating, from endoscope lens, capsule lens to special-required rod lens, engineers in Photonchina implement strict production process to ensure stable quality, good yield, competitive price as well as responsive lead time.

A fast telephoto prime, the Nikon F, Sigma SA and Canon EF-mount 135mm f/1.8 DG HSM from Sigma pairs bright and sophisticated optics with intuitive handling and design. As part of the Art line of lenses, this 135mm f/1.8 is designed for high-resolution rendering, and utilizes FLD and SLD glass to control chromatic aberrations and color fringing for notable clarity. A Super Multi-Layer Coating also enhances image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions. Additionally, making it an ideal lens for portraiture, the bright f/1.8 maximum aperture pairs with a rounded nine-blade diaphragm to benefit selective focus and shallow depth of field imaging with smooth bokeh. Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. The physical design utilizes Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision. As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications. Prime telephoto lens is designed for full-frame Canon EF-mount DSLRs, however can also be used on APS-C models where it will provide a 216mm equivalent focal length. Bright f/1.8 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques. Two F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements are featured in the optical design, and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy. A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. Nine-blade rounded diaphragm contributes to a smooth and pleasing bokeh quality. The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time. The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations. The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant. This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
