A telephoto zoom is often the first lens that amateur photographers add to their kit after purchasing an SLR/DSLR. The ability to reach out and bring distant subjects up close is immensely appealing and essential for many subjects. Equipped with a focal length ranging from 70-300mm, this Tamron camera accessory helps cover relatively short to fairly long focal lengths. The Tamron 70-300mm f/4-5.6 Di LD Macro 1:2 AF is very reasonably priced for novice users and throws in surprising macro capability as a bonus. With this 70-300mm telephoto zoom lens, expanding a macro switch in the focal length range of 180mm to 300mm allows one to obtain a magnification ratio of 1:2 at a minimum focal distance as short as 37.4", enabling close-up shots of flowers, insects and other objects that normally require the use of a specially designed macro lens. Moreover, this is a zoom lens that casually offers the distant capture and foreshortening effect pleasures of the 300mm ultra-telephoto world.
This entry-level Tamron lens offers respectable sharpness to all your clicks. Closing the aperture by one stop improves matters greatly, delivering sharpness from 70mm to about 180mm. Closing down by two f-stops produces additional improvements. It features a Low Dispersion (LD) Glass for Greater Lens Sharpness. It also helps in reducing chromatic aberration (distortion in which there is a failure of a lens to focus all colours to the same convergence point) which adds to the sharpness of your clicks.
The benefit of using a lens with a 35mm image circle on a digital DSLR/SLR with a sub-frame sensor puts out amazing results. Light falloff in the corners of the frame is very low by any measure and absolutely excellent one stop down from maximum aperture.
The Tamron's 70-300mm lens allows Auto/Manual focus adjustment to be quite smooth, with a decent range of travel that makes it easy to home in on the precise focus point you need. The focus ring moves so easily though, that it's easily jostled from its setting by a casual touch.
Build, Quality and Handling:
For an inexpensive lens, the Tamron 70-300mm f/4-5.6 is solid and operates quite smoothly. All the manual triggers and buttons are tightly bound. The Tamron 70-300mm f/4-5.6 is better than what you would expect from a lens with such a low street price, a pleasant surprise in the handling department. So with so many features available for sublime photography, be sure to order yourself a Tamron AF 70-300mm F/4.0-5.6 Di LD Macro Telephoto Zoom Lens for your Nikon DSLR and take your photography skills to new heights!
