Sony DT 18-200mm f/3.5-6.3

Unfortunately, the Sony DT 18-200mm f/3.5-6.3 doesn’t feature the Super Sonic wave Motor (SSM) to cut down on AF noise.

Along with an 18-250mm model, Sony also includes the DT 18-200mm f/3.5-6.3
 superzoom in its line-up, with a virtually identical finish that carries a very simple, understated design. It’s dominated by the zoom and manual focus rings, both of which are very finely grooved. At the rear, the lens mount is predominantly plastic, and the overall feel doesn’t really reflect the asking price.
As all Sony D-SLRs feature an in-built image stabilisation system (known as Super SteadyShot), there’s no need for it in the lens. This lens has been in the Sony line-up for a couple of years now, so doesn’t feature the Super Sonic wave Motor (SSM) to cut down on AF noise. As such, without the need or inclusion of either of these features, weight has been cut down to a slender 405g. In use, the AF is very loud, with a real mechanical buzz as the motors kick in. It’s also slow, often hunting before it locked- on to the subject, and the movement through the zoom range isn’t as smooth as we’d like.
