The 24-70mm f/2.8 IF EX DG HSM Lens from Sigma is a go-to option for many photographers thanks to a versatile zoom range from wide angle to telephoto. This model is designed for Sony A-mount cameras and features a fast constant aperture of f/2.8 for shallow depth-of-field and enhance low-light imaging capabilities. The lens provides good image quality through the use of three aspherical elements, one ELD element, and two SLD elements to combat aberrations and distortion. Also, a Hyper Sonic Motor provides fast and quiet autofocus and the lens is designed to do all focusing internally. Additionally, the lens has a front filter thread of 82mm and a rounded 9-blade diaphragm.

With a powerful guide number of 200' at ISO 100 and 105mm, the?Sigma EF-610 DG ST Flash?works with Canon E-TTL / E-TTL II and offers users the ability to illuminate the subject or scene both on camera and off. The unit also has a zoom range of 24-105mm with full frame cameras and has a wide-angle panel that will extend this to 17mm. The head will tilt from -7 to 90? and rotate right 90? and left 180? for full bounce capabilities. And, it has wireless master and slave TTL functionality.

The Nikon F mount Sigma 50mm f/1.4 DG HSM Lens is a fast standard-length prime designed to achieve high optical performance through the incorporation of both three Special Low Dispersion glass elements and one molded glass aspherical element. These elements, coupled with an advanced optical design, work to minimize sagittal coma flare and chromatic aberrations in order to provide high image sharpness and clarity. The lens' large diameter and floating system also help to correct for vignetting to ensure maintained peripheral brightness. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity.

Increase the maximum magnification from 1:3 to 1:2, the AML72-01 Close-Up Lens from Sigma is a dedicated accessory for the 18-300mm f/3.5-6.3 DC Macro OS HSM Contemporary lens. This close-up lens mounts to the original lens' 72mm front filter threads and increases the magnification ratio to benefit macro shooting applications. It features an apochromatic design and maintains the original lens' quality throughout the zoom range from 80mm to 300mm focal length positions.

The?EF-530 Super DG?is?Sigma's?flagship TTL flash, and has been updated with improved coverage range and a stronger power output. It features a powerful Guide Number of 174'/53 m at 105mm, and covers a focal range from 24mm to 105mm.

The Sigma 70-300mm 4-5.6 DG Macro lens is the compact and economical choice for a telephoto zoom lens. Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300mm focal length. It is the ideal high performance lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range.

Presenting an impressively unique 180? angle of view, the Nikon F-mount Sigma 8mm f/3.5 EX DG Circular Fisheye is a creative tool for producing dramatically distorted, circular imagery. Benefitting the unique look of the lens is an advanced optical design that utilizes one SLD glass element to reduce color fringing and chromatic aberrations for improved clarity. A Super Multi Coating has also been applied to suppress lens flare and ghosting for greater contrast and color accuracy. Additionally, the lens also features a close 5.3" minimum focusing distance of 5.3", along with a 1:4.6 maximum magnification ratio, to suit working with close-up subjects.

Producing an expansive 180? angle of view, the Canon EF-mount 15mm f/2.8 EX DG Diagonal Fisheye Lens from Sigma offers a super-wide perspective for creative applications. As a diagonal fisheye, this lens produces a notably distorted image that fills the entire frame, and its minimum focusing distance of 5.9" allows for working with unique perspectives with close-up subjects. Additionally, the bright f/2.8 maximum aperture benefits working in difficult and low-light conditions by allowing the use of faster shutter speeds.

An optically advanced wide-angle prime, the Nikon F 35mm f/1.4 DG HSM Art Lens from Sigma mixes a comfortable focal length with an especially fast design. The bright f/1.4 maximum aperture helps to achieve shallow depth of field and selective focus effects, and also suits working in difficult lighting conditions. The optical layout incorporates both low dispersion and aspherical elements, which help to improve sharpness and clarity by controlling both spherical and chromatic aberrations. A floating elements system is also used to maintain performance throughout the focusing range. A Super Multi-Layer Coating is also featured, and helps to minimize flare and ghosting for greater contrast and color accuracy when working in strong lighting conditions.

An ultra wide angle zoom lens for Canon digital SLR cameras. Incorparates four FLD low dispersion elements and three aspherical elements. HSM motors for quiet high speed focusing. Suitable for Canon digital SLR cameras with APS-C sensors
