Sigma's proven APS-C standard zoom with macro capability and f/2.8 wide-end reach

The 17-70mm f/2.8-4.5 DC Macro HSM covers the focal range that APS-C shooters actually use daily, from wide environmental shots at 17mm to an useful short telephoto at 70mm. The f/2.8 maximum aperture at the wide end gives you real light-gathering ability when the scene gets dark, and the DC designation means the optical formula is built specifically for APS-C sensors than adapted from a full-frame design. Macro capability rounds out the spec sheet for a lens at this price point, letting you move in close on subjects without swapping glass.

The HSM autofocus motor drives focus quietly and keeps full-time manual override in play, useful for wedding or event work where you need to fine-tune focus without flipping a switch. The 72mm filter thread accepts standard polarizers and ND filters that many photographers already own. This is a workhorse lens for Nikon F mount APS-C bodies, and its established track record makes it a dependable choice when you want a single lens to cover most daylight and low-light scenarios.

Who It's For

Travel photographers who want one lens on an APS-C body will find the 17-70mm range covers wide interiors through portrait-length compression without a bag change. Documentary and event shooters benefit from the f/2.8 wide-end aperture in mixed or dim light. Close-up and product photographers gain macro capability without carrying a dedicated macro lens. Street photographers working on Nikon F mount APS-C bodies get a focal range that handles tight alleys and moderate reach in a single mount.

FAQ

What's the actual focal length range on an APS-C Nikon body?
17-70mm. On Nikon's 1.5× crop factor, that translates to roughly 25.5-105mm equivalent.
Why does this lens have two aperture numbers in the spec?
f/2.8-4.5 means f/2.8 at 17mm, and the aperture closes to f/4.5 by the time you reach 70mm. This is typical for standard zooms at this price point.
Does the HSM motor let you manually focus while autofocus is active?
Yes. Full-time manual override means you can twist the focus ring to fine-tune focus without switching to a manual-focus mode.
What filter size does this lens use?
72mm. That's a common size, so most polarizers and ND filters photographers already own will thread directly on.
Is this lens designed for full-frame or APS-C only?
APS-C only. The DC optical formula is built specifically for Nikon's DX crop sensor bodies, not adapted from a full-frame design.
How close can you focus for macro work?
The verified specs don't detail the minimum focus distance, but Sigma brands this as macro-capable for its class, suitable for close subjects without a separate macro lens.
When was this lens released?
2009. It's a well-established design with a solid track record on Nikon F mount APS-C bodies.
