An Incredible Lens for taking Incredible Pictures

Normally, zoom lenses with large zoom ratios experience barrel distortion while trying to maintain image sharpness. However, the Sigma 50-500mm f/4-6.3 EX DG APO HSM Lens is able to circumvent that through the use of the Triple-cam Rear Focusing System, which guarantees image precision throughout the whole focal range.

SIGMA 736306 APO 50-500mm F4-6.3 EX DG HSMThe Sigma 50-500mm f/4-6.3 EX DG APO HSM Lens feels very solid. While its substantial weight has led to it being called the “Bigma” by its followers, the lens remains quite endearing. It may be large, but it is still easy to carry around thanks to the zippered pouch and carrying strap it comes with. Thanks to its zoom lock capabilities, “zoom creep” is prevented while transporting the lens from place to place.

The mounting plate it is packaged with is very user-friendly as well, which makes the lens easy to install on the D-SLRs it is compatible with. Additionally, the mounting plate also doubles as a carrying handle. From the aperture ring to the zoom ring, everything feels snugly assembled and well-built. With its HSM (Hyper Sonic Motor) technology, autofocus is silent and quick especially when you take the lens’ wide scope into consideration.

Whereas other high zoom ratio lens aren’t able to maintain vividness as the focal length gets longer, this one is able to relatively do a good job of doing so. The picture quality doesn’t degrade as much even when the focal length is at its highest. Aside from the fact that the mechanism of this lens is well-designed, its ability to maintain image quality can be directly attributed to two things: its SLD (Special Low Dispersion) glass, and its special coating. The lens is able to avoid high levels of color aberration thanks to the four pieces of SLD glass that it is equipped with. With the lens’ special coating, flare and ghosting effects can be repelled, thus making for optimal color balance in images. In addition, a bayonet, petal-type hood can be attached to it, which prevents excessive light from degrading the quality of the image.

All things considered, the Sigma 50-500mm f/4-6.3 EX DG APO HSM Lens’ ability to provide great images at different focal lengths will surely please every serious photographer. Definitely, it is a very worthy investment.
