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

Product Information

The 144° of focus ring rotation is ideal for precision work at 70mm with adjustments happening slightly fast at 200mm, though not problematically so. Weight: 1,430 g (50.4 oz.) vs. 1,540 g (3.4 lb.) of the Nikon. Together with a full frame body you’ll be schlepping 2.3kg around. [0] Thus, all 70-200mm f/2.8 lenses I've used came with a tripod ring included, providing a balanced attachment point.

Usually, third party lens manufacturers are required to reverse engineer camera autofocus algorithms and the result is commonly the weakest aspect of these lenses. My strong preference, especially for a 70-200mm f/2.8-class lens, is to have the zoom ring behind the focus ring. The Sigma handles flare a bit better with less contrast loss, but produces more flare artifacts at specific focal lengths/aperture settings. As hinted to, images captured with APS-C format cameras do not show shading nearly as readily and the barely-recognizable close-to-1-stop of shading in 200mm corners is essentially the only consideration in this regard. I mentioned vignetting – it is always present in wide aperture corners unless using a camera that does not include the entire image circle (an APS-C model in this case).From the charts I’d expect the lens to perform on a pretty high level regarding overall contrast but with limited sharpness at the short end outside the DX image-circle. Astigmatism seems well controlled. But let’s see how this theoretical performance translates into real life results in the sharpness test based on Siemens-stars.

These long focal lengths can create excellent landscape images, especially when there is a distant subject to be emphasized, rendered large in the frame.The Sigma 70-200mm f/2.8 DG OS HSM Sports Lens has a visually attractive, very high-grade, "dust- and splash-proof" build quality that functions very well and delivers great image quality with optical stabilization aiding significantly in this regard. The Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function as well as full-time manual focusing capability for Sigma, Canon, and Nikon-D mount lenses. That this tripod foot extends forward with a rounded front helps to circumvent this problem by providing a palm rest, but a rear-positioned zoom ring works best. Having the viewfinder view stabilized permits the shutter release to be timed with the just-right composition.

It's a modest enough effect that I wouldn't fret about it too much. If you do want to remove a vignette from your image entirely, the same Lightroom lens profile that compensates for distortion will also remove it. providing 1.4x and 2.0x magnifications of the original focal length while retaining the original minimum focus distance, translating to a 1.4x and 2x higher maximum magnification spec respectively. While the focal length versatility provided by the TC is very nice, magnifying the image by 1.4x does not go unnoticed with image sharpness taking a noticeable hit at 280mm f/4. At 200mm, some softness can be seen in the closer results, but the distant results appear noticeably better.This lens delivers very sharp results across the entire frame at 70mm f/2.8 and very little difference can be seen at 70mm f/4. We'll take a closer look at the extreme full frame corners next with the extreme top-left corner featured in these results. Look for the sharpest portion of the frame at f/2.8 with the details showing the least change at f/4 indicating the center of the plane of sharp focus. The score in the “features-department” is 0[-]/6[0]/7[+]. There are no minus-points and the big pluses are the image stabilization and the low price. The lens is even cheaper than the stabilized 70-200/4.0 zooms from Nikon and Canon! So if the lens delivers solid performance it should be a winner. Motivation As always, vignetting affects wide open aperture corner brightness and contrast and that explains a primary difference seen in the f/4 results.
