Welcome to the golden age of lens technology

Looking over our lab and field tests of lenses from the past year, several trends clearly emerged—some expected (lots more wide-range zooms) and some unexpected (manual focus!). The lens choices available today are near-dizzying in their variety, so we thought we’d divide the menu into digestible chunks, tell you the pros and cons of the various classes of lenses, and provide some side dishes of technical info.

Did You Know?
Q. What is zoom creep, and how can I avoid it?
A. Zoom lenses with loose turning actions often suffer from something called zoom creep. It can be vexing when, for example, you hike with a long zoom hanging from a neckstrap and it slowly extends from a conveniently compact state to a longer, chest-thumping log. To prevent creep, some lenses have a zoom lock to maintain a compact profile. Zoom creep can also reduce sharpness. With a loose-turning lens, when the camera is aimed up or down, the zooming elements can move during exposure, resulting in a softer image. To avoid it, lock the zoom ring either with the lens’s zoom lock, or—as pros who shoot from the rafters above sports arenas do—use gaffer’s tape to tame that creep.
