Document a smaller world
When documenting the world of small objects and nature, sharpness and detail counts. Take, for example, the coin collection you've spent years developing. This Sigma Photo 70mm f/2.8 macro is an excellent choice for clear, distortion-free images, so using it will make every detail of a coin's surface sharp while filling the frame. Plus, taken out of the realm of the tiny, it doubles as an excellent portrait-length lens, capable of keeping your subject crisp while dialing back the background to a pleasing blur. And with Sigma's EX-designation denoting its high build quality, it's a lens you can depend on for many years to come.
It belongs in your camera bag too
While this macro lens is optimized for full-frame cameras, APS-C cameras can benefit as well. The focal length will increase by a factor of 1.5X on most APS-C cameras (1.6X on Canon's APS-C models), so this 70mm lens will have a 105mm equivalent length on many non-full-frame cameras. With several mountings to choose from, this lens has the versatility to find a home in almost any photographer's bag.
Carefully machined low-dispersion optical elements and proprietary coatings yield a lens that is sharp, clear, and free of artifacts like color fringing, ghosting, flaring, and distortion.
