The weight and high building indicate this lens has been created for serious use. The fast f/2.8 maximum aperture means the front element is relatively large (with a filter thread of 82mm), however the barrel itself is compact. The wide zoom ring dominates the majority of the front half and boasts a grooved, rubberised finish which makes it very easy to use. The zoom action is smooth and offers a good level of resistance, with a lock switch permitting the lens to be held at 24mm when not in use. Behind the zoom ring is the manual focus ring, that is relatively thin, but sports a textured rubberised finish for simplicity of use. It has a very nice action and can be used even if the lens is switched to AF; handy when you wish to make minor adjustments to the focusing point. An internal focus system means the front of the lens remains stationary during focus; useful when filters are attached. Other features include the Vibration Compensation On/Off switch near to the AF switch, and a focus distance window on the top rear of the lens, having a scale displaying metres and feet.

The overall build quality is excellent and the lens boasts dampness resistance to help prevent water from penetrating inside.

FEATURES: There’s no shortage of technologies as well as cutting-edge optical design here. By redesigning how the motors in the Vibration Compensation (VC) work, Tamron has delivered a lightweight system with a claimed four-stop advantage. The Sony-fit lens lacks this facility as Sony Alpha models boast body-integral stabilisation. The AF system advantages from the use of an Ultrasonic Silent Drive (USD) for quiet and also fast AF, with electronic manual focusing also possible.
The SP’ designation signifies this lens is one of Tamron’s premium optics and this is demonstrated by the sophistication of the optical construction, which boasts three LD elements made from high-grade optical glass, three glass-moulded aspherical lenses, one hybrid aspherical lens and also two Extra Refractive Index (XR) glass elements.

While this types of lens isn’t made for close-ups, the minimum focus of 38cm and maximum magnification of 1:5 (one-fifth life-size) will get you fairly close to subjects.

PERFORMANCE: TheTamron zoom performs excellently in all key areas. The actual autofocus on our Canon-fit sample provides fast and also responsive AF. locking on quickly without hunting. It may not quite match the big guns for speed, however the difference will be negligible for most users. The USD focusing motor is near-silent, too. and also delivers a performance that isn’t too far off Canon’s famed USM technique.

In case youve actually questioned if third-party lenses can really perform as well as marques, this zoom could change your perception.
The optics are excellent, being sharpest at its wide-angle end. with sharpness proving good at f/2 .8 to excellent at f/8. As you zoom through the range, the optics deliver a similar performance, while at 70mm. sharpness remains very good at f/8. Chromatic aberrations aren’t a problem, while fringing and distortion are both extremely well controlled. Light fall-off is evident at the wider focal lengths when the lens is used wide open, but close the aperture a couple of stops and this problem is eliminated.

The Vibration Compensation facility is a real reward when shooting hand-held in low light and our tests showed it offers a definite three-stop advantage brilliant when you are shooting in challenging situations.
