To maintain high optical performance from infinity to close-up 1:1 macro photos without accessories, the Sigma 50mm f/2.8 EX DG incorporates a "Floating Internal Focusing" (FIF) system. As a result, the lens also features a non-rotating front lens group which makes it easier to work with polarising filters, and has a focus limiter to narrow down the broad focus range.

The smc FA 45mm f/2.8 Lens from Pentax is a moderately wide angle lens with a 35mm format equivalent focal length of 35.5mm and a 63 degree angle of view. Used by many as a substitute for the 75mm lens it's a favorite with street and wedding photographers alike and also ideal for landscapes. Its fast 2.8 maximum aperture is brighter in the viewfinder and allows low light shooting without hiking up the ISO, renders artfully blurred backgrounds and permits higher shutter speeds in standard lighting conditions.

This large-aperture medium macro lens delivers an angle of view equivalent to 70 mm in 35 mm size and 105 mm in APS-C size. A Special Low Dispersion (SLD) lens and two high refractive index SLD lenses provide excellent correction for chromatic aberration during close-up photography. "Super Multi Layer Coating" of this lens minimises the occurrence of flare and ghosting. The floating focus system provides extremely high optical performance from infinity to 1:1 Macro. It's the ideal lens for all close-up work as well as for landscapes and portraits.

The Pentax DA 18-55mm f/3.5-5.6 AL WR Zoom Lens is a standard focal length zoom lens designed specifically for Pentax digital SLR cameras. Blending versatility with affordability, it has a broad range of applications from indoor pictures, portraits, and landscapes to family photos and other general situations. This lens is weather resistant to handle damp, inclement conditions, and has a great wide angle capability with a standard 3x zoom range.

Extreme focal lengths are a challenge, particularly in digital SLR photography. The smc-DA 12-24mm f/4 ED (AL) offers you a lens that permits a total range of wide-angle photography. Utilising aspherical and particularly low-dispersion (ED Lenses) lens elements, crystal-clear sharpness and photos with marvellous colour depth are assured. The lens covers a picture angle range between 99 and 61 degrees, which corresponds to a focal length of 18 to 36mm in 35mm film format.

The smc PENTAX-DA Zoom 18mm-55mm f/3.5-5.6 AL is exclusively designed for use with PENTAX digital SLR cameras. This compact, lightweight standard zoom lens features an image circle matching the cameras large 23.5mm x 15.7mm image sensor. Compared with 35mm format counterparts offering similar optical performance, it is more portable and more affordably priced. When mounted on a PENTAX digital SLR, it assures comfortable, well balanced operation.

The smc FA 75mm f/2.8 Lens from Pentax is a standard or normal lens with a 35mm format equivalent focal length of 59mm and a 40.5 degree angle of view that closely approximates the human field of vision. The focal length allows a relatively simple 6 element/5 group lens design that produces sharp detail with a minimum of aberrations. The 75mm f/2.8 renders images without curvature of field found in wide angle lens or the flatness and compression found in telephotos.

The Sigma 70-200mm f/2.8 EX APO Pentax Fit lens is brilliantly designed to record further distances. Ideal for motorsport and wildlife photography, the lens delivers quality images everytime. The incredibly well made casing make it a desirable lens to record the subjects you wish to.

A versatile wide-angle to telephoto zoom for Pentax DSLRs, the HD PENTAX DA 16-85mm f/3.5-5.6 ED DC WR Lens offers a 24.5-130mm-equivalent focal length to benefit working in a wide variety of shooting situations. One extra-low dispersion glass element and three aspherical elements have been incorporated within the optical design to minimise chromatic aberrations and distortion throughout the zoom range and an HD (High-Definition) coating has been applied to maintain light transmission and reduce surface reflections. Additionally, an SP (Super Protect) coating has also been applied to the front and rear lens surfaces and an overall weather-resistant construction benefits this lens' use in a wide array of working conditions.

The smc FA 645 150mm f/2.8 IF Lens from Pentax is a medium format, manual and autofocusing telephoto lens with a 35mm-equivalent focal length of 118mm. Its fairly fast f/2.8 maximum aperture enables effective low-light shooting with pretty shallow depth of field, and helps produce a natural out-of-focus (bokeh) effect for backgrounds. High-refraction and extra-low dispersion glass help minimise chromatic aberrations and allow for sharp imaging performance with high contrast and clarity. The Super Multi Coating also contributes to high sharpness and contrast. An inner focus system is used to minimise lens extension when focusing, allowing for a closer minimum focus distance. A large hood with a PL filter operation window is included to enable the use of a circular polarising filter while checking the results through the camera's viewfinder.
