The latest optical design provides an overall length of 94.7cm /3.7inch. It isn’t perfect but it is a fine lens that is definitely worthy of consideration by anybody who is in the market for a pro-spec, full-frame standard zoom. The Sigma 24-70mm f/2.8 Ex Aspherical IF Ex DG HSM AutoFocus Zoom Lens is a large aperture standard zoom lens that covers focal lengths from 24mm and is housed in compact construction.

This is a shame given that the primary advantage of any fast lens is the ability to take advantage of low aperture numbers – but from f/4 right through to minimum aperture its MTF figures are above the critical 0.25 cycles-per-pixel threshold. Optically, the Sigma 24-70mm f/2.8 IF EX DG HSM lens is rather weak when used wide-open.
The focused-distance window includes markings that indicate depth-of-field for the 24mm focal-length setting but there are no markings for other focal lengths. Sigma has provided just the right amount of resistance on the manual-focusing ring, but the zoom ring is a shade on the heavy side. Under other circumstances this change of grip might have left the lens feeling rather unbalanced but the Sigma’s compact dimensions largely avoid this problem. The zooming ring is wider and positioned to the rear, meaning that the left hand’s grip has to be shifted closer to the camera body. It nestles very comfortably in the hand with the manual-focusing ring falling naturally under the thumb and second finger. Nothing appears to have been sacrificed in terms of build quality – the Sigma’s matt-black zoom feels solid and looks at home on the front on a Nikon D700. The big question, therefore, is whether this less expensive lens is a true bargain or simply an inferior corner-cutting pretender. Whereas Canon, Nikon and Sony all pitch their 24-70mm f/2.8 zooms in the £1,400 to £1,500 RRP bracket, Sigma’s lens is just £900 by comparison – and that’s before any on-the-street price discounts. The first thing to note about Sigma’s 24-70mm f2.8 lens is its considerably lower cost than other premium zooms. Sigma’s pro-spec 24-70mm f2.8 full-frame zoom lens is available in Canon, Nikon, Pentax, Sony and Sigma mounts, and was tested here in conjunction with a Nikon D700 (full-frame) body. The Tamron is untroubled by it but even the Zeiss has some at its widest.Sigma 24-70mm f/2.8 IF EX DG HSM lens review Compare Sony FE 70-200mm f 2.8 GM OSS II Lens vs Sigma 24-70mm f 2.8 DG DN Art Lens for Sony E vs Nikon NIKKOR Z 70-200mm f 2.8 VR S Lens. At 24mm and to a slightly lesser degree at 28mm it’s noticeable in the corners at every aperture. Perhaps the biggest drawback with the Sigma is the high CA. Stopping down just one stop to f4-5.6, however, soon shows the superior uniformity of Zeiss. : Sigma 24-70mm f/2.8 IF EX DG HSM AF Standard Zoom Lens for Nikon Digital SLR Cameras : Digital Slr Camera Lenses : Electronics. The Sony Zeiss model on the other hand is without doubt the best, but wide open at 35mm and 40mm the Tamron isn’t so far behind. The Sigma and Tamron perform quite similarly although the former has higher central sharpness at the shorter focal lengths, the Tamron is the better performer of the two from 35mm to 75mm (at least up to f8). Looking at the models it’s not an easy choice.
Īlthough Tamron make a newer SP AF 24-70mm f2.8 Di USD (ultrasonic) model, the price is $1,299, yet the older lens is just a fraction of the cost at $499. We’ve also taken the opportunity to compare with it the Tamron SP AF 28-75mm f2.8 XR Di LD Aspherical. We’ve compared the Sony mount Sigma with the Sony Zeiss Vario-Sonnar T* 24-70mm f2.8 ZA SSM, a huge lens with an equally impressive optical construction and $1,599 price tag.
