This super-wide-angle lens is ensured minimal light-fall-off with superior peripheral brightness. The iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus images in the foreground and background. This is an ideal DG lens optimized Digital SLR camera.The minimum focusing distance of this lens is 20cm (7.9 inch) and it has maximum magnification of 1: 4 with fast F 1.8 maximum aperture. The minimum focusing distance of 20cm (7.9 inch) and 94.5? angle of view allow close up photography surrounding the photographic subject.The lens incorporates Dual-Focus (DF) mechanism. It is easy to hold the lens, since the focusing ring does not rotate during auto-focus, yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens. The rear focus system eliminates the need for the front of the lens to rotate, thus allowing the use of a "Petal-type hood", which is superior light blocking effect.The use of aspherical lens elements in both of the front and rear lens groups effectively compensates for distortion, spherical aberration and astigmatism.

A telephoto lens with a focal length equivalent to 300mm on a 35mm film camera, is unprecedented in combining a first aperture of f2.0 with exceptionally compact size, low weight, and telephoto power. It offers, thanks to the use of Super ED and ED lens elements, exceptionally sharp imaging with an absolute minimum of chromatic aberration. It also has superb defocusing characteristics that make it possible for photographers to precisely achieve their creative goals.

Tamron 2X Teleconverter for Canon EOS mount cameras

Sigma 24mm f1.8 EX DG Aspherical Macro is one of the EX Series lenses. This lens has a fast F1.8 maximum aperture with macro focusing capability of minimum focusing down to 18cm/7.1inches (reproduction ratio 1:2.7). The iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus image. It incorporates the floating focus system and uses two aspherical lens elements for minimizing distortion and spherical aberration and astigmatism. Internal focus system eliminates front lens rotation, thus allowing the use of a Perfect Hood and the easy use of polarizing filters. The lens incorporates non-vignetting optical construction, in order to obtain adequate peripheral brightness even at open aperture. This is desirable for digital cameras. The lens also incorporates dual-focus mechanism. It is easy to hold the lens, since focusing ring does not rotate during auto-focus, and yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens. The lens materials used in this new lens are lead and arsenic free ecological glass.

Digitally Integrated Design (Di) is a designation Tamron puts on lenses featuring optical systems designed to meet the performance characteristics of digital SLR cameras.Tamron introduces a new version of the famous 90mm macro lens for film and digital photography. Tamron's 90mm macro lens, often referred to as "the portrait macro" and loved by photographers all over the world, is now reborn as a Di lens that is perfect for use with both film and digital cameras.

A Teleconverter is a great way to extend the focal length of your lens. This Teleconverter will extend the focal length of your lens by 2x giving more magnification. The Tamron Pro series Teleconverter offer superior optical construction for improved image quality.

Compact, wide-angle lens which enables tilt and shift movements. The floating optical system, with an aspherical lens element, corrects distortion and other aberrations. High image quality and compactness are the result. Great for architecture, landscapes and other wide-angle shots.

Digitally Integrated Design, is a designation Tamron puts on lenses featuring optical systems designed to meet the performance characteristics of digital SLR cameras. This lens employs an IF (Internal Focusing) system that maintains the overall length of the lens during focusing. It uses two LD (Low Dispersion) glass elements that effectively compensate for chromatic aberration. Providing high-contrast, outstanding image quality and a soft out-of-focus background effect it incorporates an AF/MF one touch switchover mechanism built into the focus ring (for Canon & Nikon only). Super performance series provides high performance through outstanding design specifications. The lens features the new FEC (Filter Effect Control) function that enhances operational ease of Polarizing Filter use. The new Filter Effect Control is designed to rotate the filter to the desired position while the hood is attached. This is accomplished by turning the FEC ring that in turn rotates the portion of the filter mount where the filter is mounted.

A Teleconverter is a great way to extend the focal length of your lens. This Teleconverter will extend the focal length of your lens by 1.4x giving more magnification. The Tamron Pro series Teleconverter offer superior optical construction for improved image quality.
