Sony's been building the gear used by professional videographers and broadcasters for decades. So it's no surprise to see that expertise trickle down into an SLR lens like this constant-aperture 18-105mm f/4 power zoom lens. With an equivalent focal length of 27-157mm and a compact design weighing barely over 1 pound, you've probably figured this is a good candidate for a travel lens. But add an ultra-quiet power-zoom motor that allows silky smooth zooming over a 5.8X range, and you've got a lens that's tailor-made for your next video production, too.
The wide maximum aperture gives you extra flexibility to get the shot in low light, and when zoomed in it does a nice job with portraits, defocusing the background to give a pleasing isolation of your subject in space. When you need a lens that's got the ability to gather unique still shots and dynamic, sharp video from a distance — all in one remarkably compact package — the SEL-P18105G should be on your short list.
