In addition to the wide-angle to mid-range telephoto zoom, the lens features a large 2.8 aperture. Extra-low dispersion glass works to reduce ghosting, flare, and chromatic aberration, while asperhical lens elements also correct aberrations at wide-angles. 0.2x Magnification 24-75mm Zoom (35mm Equivalent) f/2.8-22 72mm Filter Diameter Sony A-Mount

The Sony SAL-18250 DT 18-250mm f/3.5-6.3 Autofocus Lens is a compact, wide-angle to long-telephoto zoom lens specifically designed for the Sony Alpha and Minolta Digital SLR cameras. This long zoom range translates into a 14x zoom ratio. This lens is relatively very compact, and the optics have been optimized for the small diameter image circle in order to work with the APS-C size CCD used with digital SLR cameras.

Specifically designed for digital SLR cameras equipped with APS-C size image sensors, the Sigma 10mm f/2.8 EX DC HSM Fisheye Lens is a lens that captures a rectangular 167° view in all directions (when mounted on Canon SLR camera). The diagonal field of view of this fisheye lens produces striking images with exaggerated perspective and distortion.

The Sigma 10-20mm f/3.5 EX DC HSM Autofocus Zoom is a super-wide angle lens with a relatively bright f/3.5 maximum aperture throughout its zoom range, helping to ensure high image quality. The lens gathers enough light to make it a great choice for indoor shooting as well as landscapes and creative portraiture.

The Tokina 11-16mm f/2.8 AT-X 116 Pro DX Lens is an ultra wide angle zoom/lens specifically designed with a mount for use with Sony Alpha digital SLR cameras with an APS-C size sensor. The slightly shorter zoom range of this lens over the popular and award winning 12-24mm lens makes it possible to maintain optical quality even at wide-open apertures. This lens features a fast constant aperture of f/2.8, and provides a focal length equivalent to 17-25mm in 35mm format.

The Sony E-Mount 18-200mm f/3.5-6.3 Zoom Lens for NEX Camera is a can-do lens--an 11 x 27-300mm (35mm equivalent) zoom that can handle everything from wide landscape photos to portraits to sports, action and even wildlife photography with the telephoto up to 300mm. And the results will be brilliant, with four aspherical elements that correct visual aberrations across the entire zoom range, a quiet AF motor for improved sound recording with video, and optical Steady Shot image stabilization (with Active mode) for steadier handheld shots while on the move. A circular aperture provides more pleasing out-of-focus areas. This lens is not recommended for use with full-frame DSLRs.

The Sigma 4.5mm f/2.8 EX DC HSM Lens is a spherical fisheye lens that easily captures a full 180° view in all directions, in a circular image. Even the most familiar and mundane of subjects can be portrayed with startlingly fresh new expressions through exaggerated perspectives and unusual distortion effects. It is well suited for academic and technical measurements such as solid angle measurements, cloud cover measurements & virtual reality.

The super wide-angle 122 to 84.1 degrees zoom range of this lens makes it ideal for the tightest of interiors, as well as for dramatic landscape photography. Using effective arangment of lens elements and advanced technology this lens has super compact dimensions of only 3.9 inches full-length, and 3.4 inches maximum diameter. It is equipped with an Inner Focusing system that will keep the length of the lens unchanged while controlling aberration.

The Sigma 24-70mm f/2.8 IF EX DG HSM Lens is a large aperture standard zoom lens that covers a range from wide angle to short telephoto. It is ideal for general photography such as snapshots, portraiture and landscapes.
