The Sony DT 16-105mm 1:3.5-5.6 was announced in September 2007, as a premium kit lens to accompany the Alpha 700 DSLR. Sony has thankfully (and uncharacteristically) managed to avoid the over-proliferation of letters which afflict lens names from other manufacturers, with just the 'DT' badge (for Digital Technology) indicating that the design is optimised for cameras with APS-C imagers. Sony's information also reveals that the lens incorporates one ED (Extra-low Dispersion) glass element and two glass aspherical elements, promising minimised colour aberration and excellent contrast across the zoom range, plus a circular aperture for pleasing background blur.

However the 16-105mm is more than just an upmarket kit lens, and offers arguably the most interesting focal length range of any DSLR lens currently available, ranging from a 24mm-equivalent wideangle to a 160mm-equivalent telephoto; indeed for many photographers the wider-than-average angle of view will be more useful than the extended telephoto ranges found on the current crop of superzooms. This follows in something of a tradition for this lens's Minolta predecessors, which included a 24-105mm standard zoom for 35mm SLRs when other brands only offered 28-105mm lenses. Adding to the attraction is the fact that this is achieved within a compact, lightweight package, ideal for travel or just general purpose 'walkaround' use. So does this new kid on the block have the substance to spearhead Sony's intended drive towards DSLR world domination? Let's find out.
