A well built standard zoom lens for DSLR cameras with ‘APS-C sized’ sensors.Tamron has tagged its new 17-50mm F/2.8 lens with the ‘SP’ label, indicating Super Performance, which puts it into the professional product category. It also bears the Di II, indicating a second-generation, digitally integrated lens that is designed for use with ‘APS-C sized’ sensors and mounts are available for Canon, Nikon and Sony DSLRs. As tested on a Canon EOS 300D, it covers a field of view equivalent to approximately 27-80mm.
Sigma’s new 18-200mm F3.5-6.3 DC zoom lens is marginally heavier than the similarly-featured Tamron lens we reviewed in issue 25 but also somewhat smaller in size and considerably cheaper. Designed specifically for current DSLR cameras with ‘APS-C’ sized sensors (1.5-2.0 field of view crop), this lens has internal focusing, which prevents the front from rotating, making it ideal for use with angle-sensitive accessories like polarisers and graduated filters.
Digital integration is now available for a popular long-range zoom 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.
