The macro function is particularly useful and easy to use, offering various zooms by simply zooming in or out. The wide-angle to portrait zoom range covers the usual needs of most of us and comes in a lightweight body that won't feel anchored. To do this, Sigma uses a tough plastic that can withstand a lot of damage, which hopefully your lens won't have to suffer. Some people miss the steel body metal lenses of the past, but I enjoy the convenience of today's lighter lenses. I find my Sigma 28-80 shots are sharp at all focal lengths and can zoom to letter size and even 11x14 with no problem. You can get a little more sharpness with an equivalent Nikon lens for a lot more money, but unless you blow your photos to poster size or money isn't an issue, I'd rather spend my money on extra equipment, maybe even an extra lens.
