For crop frame cameras only! The Tamron 18-270 was arguably our favorite of the crop-sensor superzoom lenses. The 15x zoom is the largest zoom range of any such lens, and at 18mm the Tamron actually covers a bit of the wide angle range. The Vibration Control system helps get sharp images at the telephoto end. And now it comes with the Piezo Drive motor (ultrasonic motor for those of you who don’t speak Tamron).
That should make it quieter and perhaps focus a bit faster. The updated lens is also a bit smaller and lighter than the old one and that is welcome.
