Sigma APO 120-400mm F4.5-5.6 DG OS HSM review:

If you need a versatile telephoto zoom lens for your SLR, then consider the Sigma APO 120-400mm F4.5-5.6 DG OS HSM, which allows a variety of adjustable focal lengths to suit your needs. Not only does it do that, but it also incorporates the use of a rear focus system, which minimizes fluctuation of aberration caused by focusing. If you need an above average performing, high-quality camera lens, this is certainly one to start at.

This model measures 3.6 x 8 inches and weighs approximately 3.86 pounds, which is slightly heavier than competing telephoto lenses. Thanks to the high-quality elements in the lens itself, high image quality is assured all the way through. This multi mount camera lens has a minimum focusing distance of 150cm, and maximum magnification of 1:4.2, which makes it very useful for close-up photography. If you are tired of the usual close-up or medium range shots, then consider this telephoto lens and journey into the wild with your SLR ready.

Performance

This lens incorporates a HSM (Hyper Sonic Motor), which guarantees a quiet and high-speed autofocus, as well as full-time manual focusing capability. This may not be the quickest telephoto lens available, but it is one of the most featured. Needless to say, if you are going to venture out into the country, or travel to the beach, or even to the local park, you shouldn't go far without a long-range lens, and the Sigma APO 120-400mm F4.5-5.6 DG OS HSM is a great fit.

Ergonomics

Weighing in at more than a pound heavier than the competition, this telephoto lens is bulkier than most, which may frustrate some users. If you have never experienced a long-range lens before, you may have some difficulty setting up a shot. Although this lens does not target a specific digital SLR camera model, it is versatile across many camera platforms. If it was a little lighter and less bulky, then it would be a definite "must-buy."

Summary

Despite being bulky, heavy, and expensive, the Sigma APO 120-400mm F4.5-5.6 DG OS HSM is a high-quality, fast-performing telephoto lens that won't let you down. Because it features Sigma's exclusive Optical Image Stabilization, now you can rest assured that your photos will come out straight every time. Before you take your SLR into the wilderness, make sure to bring this lens along in case you get inspired by all that is before you.
