I have the
Sigma Zoom Wide Angle-Telephoto 28-70mm f/2.8-4 Compact High Speed Zoom Autofocus Lens for Nikon D. Although it isn't Nikon glass, I've had some great results -- and it's very wide on a 35mm system. Here's what the manufacturer had to say about this lens: "Sigma 28-70mm f2.8-4 High Speed Zoom lens features a large aperture, light weight and compact dimensions. At 28mm focal length this lens has a fast f2.8 maximum aperture. The lightweight of 8.6 oz./245g and 2.4"/6cm full-length makes this very compact. The size and weight of this standard lens makes it very suitable for landscape photography, and snapshots. This lens has a minimum focus distance of 19.7"/50cm at all focal lengths. It incorporates an aspherical lens element to minimize distortion. The lens materials used in this new lens are lead and arsenic free ecological glass."
