Sigma 70-200mm f/2.8 APO EX DG HSM Optical Stabilised Telephoto Lens Nikon Fit

Product Information

Because they do not, we get aberrations caused by various wavelengths of light being magnified and focused differently. Using the Sigma USB Dock (more on this later) and a custom mode, the autofocus range can be customized as desired. Only very minor traces of lateral chromatic aberration can be seen towards the edges of the frame at 70mm, and there's even less at 200mm.

Towards the rear, there’s a smorgasbord of switches, enabling the selection of two autofocus modes with priority given to either automatic or manual-override focusing, as well as fully manual focusing. Image stabilization has now been available in camera lenses for a long time, but I still love this feature and I often count on it making a clear improvement in my images. The 'OS' stands for 'Optical Stabilizer', this being is the first image-stabilized fast telephoto zoom to emerge from a third-party lens maker. Place a bright light source such as the sun in the corner of a complex, high-count lens element/group design and some effects of flare are going to be seen.While the narrower AOV does not greatly change the uses list for this lens, these AOVs make widely-framed portraits less ideal and many will prefer this AOV range for sports and wildlife pursuits. It was announced back in February alongside four other lenses, as Sigma stole the show at an otherwise-quiet PMA 2010.

Sigma 70-200mm f/2.8 DG OS HSM Sports review

Within the first minute of having it on the camera, I had painfully pinched a finger between the body and foot. The interior of the lens is ribbed to avoid light reflecting into the lens and the exterior features a thin mold ribbed ring and rubberized rear section to aid in grip during installation and removal. A 70-200mm lens is my most-used studio lens, working especially well for product images and many other general studio applications.

At 150mm there is a loss of performance: Astigmatism creeps back into the FX-corner and haloing starts to mar the DX-corner too. Unless your wildlife subject is very large and/or very close, the longest native focal length in this lens (I'll discuss the teleconverter options later in the review) will usually be found far too short for this task. While there is some plastic feel to the lens, it seems quite well-built and the quality finish looks nice, providing assurance that the Sigma 70-200 Sports is a quality product. With the TC-1401 mounted behind the 70-200 Sports, autofocus speed remains good and focus hunting was not an issue even in low light conditions as long as some contrast was available for the AF system to lock onto. With long focal lengths and a wide aperture, that this lens can create a strong background blur is unquestionable.
