Sigma 24-60mm f/2.8 EX DG Asp is a compact zoom lens with a large aperture. With an overall length of 84.7mm, it is the smallest zoom lens in its class?. It is capable of taking pictures at close quarters, with a minimum focusing distance of 38cm at all focal lengths and a maximum magnification ratio of 1:5.8. It is a very effective lens for close-up photography.
Two Special Low Dispersion (SLD) glass elements are provided for effective compensation of color aberration, which is a common problem with wide-angle lenses. Four aspherical lenses, one moulded glass type and three hybrid aspherical types, offer excellent correction for distortion as well as all types of aberration. The design concept of this lens is especially suitable for the characteristics of Digital SLR Cameras.
New coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance.
This lens has excellent correction for “vignetting”, which is a common problem of large aperture lenses. The design ensures sufficient illumination of the corners of the image.
The Pentax HD Pentax DA 20-40mm f/2.8-4 ED Limited DC WR Lens is a high performance standard length zoom lens for K-mount APS-C cameras. Its 35mm focal length equivalency is 30.5-61.5mm providing a versatile and practical range for wide-angle to standard length shooting. It is the first zoom lens in the Pentax Limited Series line and brings with it a durable, weather-sealed body, HD lens coating and an optical design consisting of one ED element and one super-low dispersion element.
The f/2.8-4 maximum aperture enables effective low light shooting and, at the wide-angle end, control over its shallow depth of field for images that place sharp focus on the subject with a pleasing out of focus background. An in-lens direct current (DC) focus motor provides smooth and quiet autofocus action and its Quick-Shift Focus System enables rapid shift from autofocus to manual focus mode.
The lens barrel and the included hood are made from high-grade aluminum alloy, distance and depth of field scales are clearly marked on the barrel and a smooth rotating, knurled ring provides manual focus control. SP (Super Protect) coating on the front and rear lens elements repels dust, water and grease to help maintain peak performance.

The Pentax HD Pentax DA 40mm f/2.8 Limited Lens from is a pancake-style prime normal-length lens providing a 35mm-equivalent focal length of 60mm. The standard 39° angle of view is well-suited to everyday situations and the slim profile is ideal for an inconspicuous shooting style. A high-grade multi-layer HD coating has been applied to lens elements to help minimize flare and ghosting for enhanced contrast, clarity, and color fidelity and a seven-blade diaphragm contributes to an aesthetic out-of-focus quality to benefit shallow depth of field imagery. Additionally, an SP Protect coating has also been applied to the front lens element to effectively protect it from dirt, oil, and finger prints.
The compact form-factor of this lens integrates Pentax’s Quick-Shift Focus System, which allows manual focus control over the lens at any time, even in AF mode, for precise handling over the focal plane.
Prime normal-length lens provides a 35mm-equivalent focal length of 60mm, covering a natural perspective that is well-suited to everyday applications.
Slim, pancake-style lens measures just 0.6″-thick.
High-grade multi-layer HD coating minimizes lens flare and ghosting to enhance contrast and color neutrality.
Quick-Shift Focus System enables manual focus control at all times for precise handling that is well-suited to selective focus imagery.
Super Protect coating helps to protect the front lens element from dirt and finger marks.
The Sony 70-200mm f/2.8 G SSM II Lens is a versatile zoom lens covering portrait-length to telephoto perspectives and featuring a constant f/2.8 maximum aperture for enhanced low-light shooting and focus control throughout the zoom range. A Super Sonic Wave Motor (SSM) focusing mechanism provides fast, smooth, and quiet focusing performance with enhanced tracking capabilities that are well-suited to photographing quickly moving subjects. Also helping to increase focusing speeds is the integration of a Focus Range Limiter, which enables you to set pre-defined limits for the lens to focus within for faster response times. Additionally, when paired with Sony A-mount cameras, in-body image stabilization renders this lens stabilized and supports the use of longer shutter speeds with a reduction in appearance of camera shake.
The optical design employs two extra-low dispersion elements to minimize chromatic aberrations throughout the zoom range as well as heighten image clarity and overall sharpness. A Nano AR (anti-reflective) coating has also been applied to lens elements in order to reduce lens flare and ghosting for more contrast-rich imagery and high color neutrality.
The Sony Alpha a77II DSLR Camera is a versatile and advanced digital camera featuring a 24.3MP APS-C-sized Exmor CMOS sensor and BIONZ X image processor to produce high-resolution still images and full HD movies with marked low-light quality and sensitivity to ISO 25600. Beyond notable imaging traits, the image processor also lends itself to continuous shooting up to 12 fps for up to 26 RAW frames. The processor and sensor combination are also significantly benefitted by the unique Translucent Mirror Technology, which effectively directs light to both the image sensor and focus sensor simultaneously. This enables the expansive 79-point AF system, which includes 15 cross-type points, to work continuously even while recording video and photographing in a continuous shooting mode.
For live view monitoring, image playback, and menu navigation, both a large rear monitor and detailed electronic viewfinder are available. The 3.0″ 1,228k-dot LCD screen features a three-way tilting design to facilitate easier use from both high and low angles and also incorporates WhiteMagic technology for easier viewing in bright conditions. The 0.5″ 2.359k-dot Tru-Finder OLED EVF offers 100% frame coverage and a refined optical design to provide a natural viewing perspective and magnification. The dust- and moisture-sealed magnesium alloy body also houses a configurable user interface, built around several customizable buttons and control dials, for efficient and intuitive access to frequently used camera settings. Additionally, a Multi-Interface shoe is available for attaching external flashes, lights, or microphones.
Built-in Wi-Fi connectivity, with support for NFC-enabled devices, is also integrated into the a77II to support remote camera control and image sharing to linked mobile devices.
