Digital integration is now available for a popular long-range zoom lens.
Nikon AF-S DX Zoom-Nikkor 17-55mm f/2.8G IF-ED Lens
This professional quality, mid-range zoom lens has been designed specifically for the ‘APS-C’ sized sensors used in all of Nikon’s DSLR cameras and is quite a different beast from the 18-55mm lens supplied with the D50 camera reviewed in this issue. Covering a picture angle equivalent to 25.5~82.5mm on a 35mm camera, it maintains its fast f2.8 maximum aperture throughout its zoom range, giving it a big advantage over the cheaper optic for photographers who shoot in dim lighting and those who require a high level of depth-of-field control with differential focusing.
Nikon AF-S DX Zoom-Nikkor 55-200mm f/4-5.6G ED Lens
Purchasers of Nikon DSLR cameras that come with 18-55mm or 18-70mm lenses will probably want a long zoom to extend their shooting capabilities. The recently-released AF-S DX Zoom-Nikkor 55-200mm f/4-5.6G ED has been designed specifically to meet this need. Available in black or silver (to match the D50), it can be used for subjects as diverse as candid portraits, sports, nature and wildlife photography.
Canon EF 70-300mm f4.5-5.6 IS USM Zoom Lens
An affordable long-zoom lens with two effective image stabilisation modes.Released concurrently with the EOS 5D, Canon’s EF 70-300mm f/4-5.6 IS USM telephoto zoom lens replaces the 10-year-old EF 75-300mm f/4-5.6 IS USM lens. We tested it on Canon’s new EOS 30D, where it covered a focal length range equivalent to 112-480mm in 35mm film format. The new lens combines ultra-low dispersion (UD) and aspherical lens elements and includes an improved optical image stabiliser (IS) that allows users to shoot at approximately three shutter speed increments slower than a non-stabilised lens. This is a one-stop improvement over its predecessor.
Sony SAL75300 75-300mm f/4.5-5.6 Zoom Lens
A lightweight tele-zoom lens with an excellent price/performance ratio.Sony’s SAL75300 75-300mm f/4.5-5.6 lens partners the 18-70mm kit lens in some twin-lens kits. Compatible with both APS-C and 35mm ‘full frame’ Alphas, on the A55 body we used for our tests it provided focal lengths equivalent to 112.5-450mm in 35mm format. This range is useful for portraiture and shots of wildlife and also handy for close-ups of flowers and other small objects, where the lens will focus down to 1.5 metres.
Sony SAL135F18Z 135mm F1.8 Sonnar T* Lens
A fast, high-performance telephoto prime lens with above-average close-up capabilities.One of the first Carl Zeiss lenses to go on sale for the Sony DSLRA100 camera, the 135mm F1.8 Sonnar T* is relatively large and heavy, with a massive front element. It’s also extremely well-built, as you’d expect from a high-quality prime lens with a longish focal length. The T* designation indicates special multi-layer coatings on the lens elements to maximise light transmission and contrast. Claimed as the brightest telephoto lens in its class, it has nine aperture blades which close on a circular aperture, providing outstanding bokeh (out-of-focus blur).
Sony DT 50mm f/1.8 SAM Lens
A fast 50mm prime lens designed for Sony’s Alpha DSLRs with APS-C sized sensors.The DT 50mm f/1.8 SAM lens was introduced as one of four lenses announced with the A230, A330 and A380 DSLR cameras in early May 2009. The DT 50mm f/1.8 SAM lens is the first DT prime lens Sony has introduced and it’s being promoted as a ‘portrait’ lens. This is logical because it provides a focal length equivalent to 75mm (in 35mm format) when mounted on ‘APS-C’ camera bodies.
Sony DT 35mm f/1.8 SAM Lens
A new prime lens for general photography makes a welcome addition to Sony’s ‘Easy Choice’ lens range.The DT 35mm f/1.8 SAM (SAL35F18) was one of three new lenses announced by Sony in July, 2010. Designed to provide an affordable, compact and lightweight prime lens with a popular focal length for both entry-level and advanced photographers it’s less than one fifth of the price of Sony’s other 35mm prime lens, the SAL35F14G, which retails for $2,699 and is the only in line-up.
Sony DT 18-250mm F3.5-6.3 Zoom Lens
An extended-range zoom lens that covers a useful focal length range and provides above-average optical performance.Scheduled for release in October, at around the same time as the new Sony DSLR-A700 camera, the DT 18-250mm F3.5-6.3 zoom lens covers a 14x zoom range that is equivalent to 27-375mm on a 35mm camera. This well-built optic weighs only 440 grams and is reasonably compact. It can focus down to 45 cm to give a close-up magnification of 0.29 times.
Sony DT 11-18mm f4.5-5.6 Lens
A capable wide-angle zoom lens for Sony’s Alpha DSLR-A100 camera.Sony’s DT 11-18mm super wide zoom lens represents a minor evolution of the 11-18mm lens released by Konica Minolta in mid-2005 for the Dynax 5D and 7D cameras. Its DT design is ideally suited for the APS-sized CCD imager of these now defunct models – and also for the Sony Alpha A100 camera. Used on the A100 it provides angles of view between 104 and 76 degrees, which is equivalent to 16.5mm to 27mm on a 35mm camera. This is quite wide for the smaller sensor.
