This compact 18-270mm lens from Tamron offers a 15x equivalent zoom reach, ideal for use as an all-in-one lens. Don't fancy changing lenses constantly when travelling? This could be for you.
Design and features
Differentiating itself from previous Tamron lenses such as the existing 18-270mm, this lens uses the Piezo Drive motor for quick autofocusing performance. The lens has a lock on the barrel to help prevent lens creep (which does happen with this model if it's not locked in place) as well as a flower lens hood provided in the box. There's a pinch-to-remove lens cap and the filter thread is 62mm.

Along with the standard AF/MF and image stabilisation switches on the lens barrel, the zoom ring is coated in a ridged plastic, so too is the focus ring at the front. On our test camera, the, the lens balanced well on the body, with a very similar feel to the 18-135mm lens from Canon that is a kit option on the 600D. This lens is designed for crop sensor cameras such as the 600D and comes in Nikon, Canon and Sony mounts.

Performance and image quality
Like any wide-angle to telephoto zoom this lens does display some barrel distortion at its widest end, evening out through the mid-range focal length.
