Sigma EX 28-70 / 2,8 DG Expert Reviews

In conclusion, if you are considering a new lens that can provide you with decent features at a budget friendly price, then you may want to check out the Sigma 24-70mm F2.8 EX DG MACRO. While image quality is decent, its performance is hindered by a ...

This Sigma Macro 105mm F2.8 EX DG is a high performance medium telephoto...

A bit of barrel distortion, edge sharpness issues on 35mm bodies at the extremes, and contrast/flare control problems keep this from being a top-of-the-line lens. If you're expecting this lens to be equivalent to a wider Nikkor 17-35mm AF-S, downgrade ...

At very high magnification, depth of field is extremely shallow even at small apertures, a fact of life with any lens.

The Sigma 105mm f/2.8 EX DG Macro Lens is - as you can discern from the name - Sigma's entry in the fixed short-telephoto focal length macro lens category. And in this case, Sigma means a true 1:1, close-up macro lens. Like most macro lenses (the ...

CA (Chromatic Aberration) is very well controlled. Vignetting is minimal. Distortion is negligible. Although it has 8 aperture blades, bokeh (quality of OOF areas) is only OK (not as smooth as the Canon 100mm Macro for example).

The Sigma 24-70mm f/2.8 EX DG Lens is a well-built, well-spec'd lens with a decent price. It does not outperform (physically or optically) Canon's similarly spec'd EF 24-70mm f/2.8 L USM Lens, but it costs less than half as much. Pictured above ...

The Sigma 24-70mm f/2.8 EX DG Lens is sharpest at the wide end of its focal length range. At 24/28mm, the 24-70 is very sharp in the center at f/3.2. However, performance gets progressively worse as the focal length is increased. To me, 70mm f/2.8 is ...

Like the Sigma 24-70mm f/2.8 EX DG Lens, the Sigma 28-70mm f/2.8 EX DG Lens is a well-built, well-spec'd lens with a value price. But, giving up 4mm of focal length range on the wide end results in a much more compact lens. In addition, the 28-70 is ...

Sigma's zoom ring turns the opposite direction from Canon's zoom lenses - neither is better unless you are very used to one direction or the other. A zoom lock switch locks the lens in the retracted position. This switch is not necessary unless this ...
