Summary: The Sony DT 16-80mm promises to be the perfect general-purpose zoom for discerning Alpha DSLR owners. With an equivalent range of 24-120mm it zooms both wider and longer than the standard kit lens, and with the pedigree of respected lens company Carl Zeiss behind it, the DT 16-80mm should have few concerns in the quality department.
In use the DT 16-80mm can certainly deliver excellent results.
Pros: Flexible general purpose range., High contrast and very sharp results., Relatively small and light., Squeezes best from the Alpha system.
Cons: Build quality not a big upgrade over kit lenses., AF noise and speed similar to kit lenses., Manual focus ring not very smooth., Macro no better than kit lens.
Summary: For those who love to take sharp pictures with a zoom lens with a large zoom range, the Sony 16-80 mm is the right one. Too bad for the distortion at 16 mm. Hopefully, there will be firmware for Sony cameras one day to correct this already in the camera. At this time, that is not yet the case, unfortunately.
Pros: Very high resolution/sharpness, Extremely little problems with flare
Cons: At 80 mm, the resolution at full aperture is less and the corners remain behind on the edges more., Visible distortion, in particular at 16 mm.
