The SAL1650 packs first-class optical performance and a versatile
zoom range into a lens that is remarkably compact and lightweight.
At the wide end you have a 16mm focal length that is ideal for
interiors, sweeping landscapes, or creating visual impact with powerful
perspective. Zoom out to the 50mm end for mid-range telephoto reach
that can bring details and distant subjects closer. What's more, you have
a constant F2.8 maximum aperture throughout the entire zoom range.
That makes shooting in low light easy, especially when the lens is used
with a body that includes SteadyShot INSIDE™ body-integrated image
stabilization. A large maximum aperture also provides plenty of margin
to stop down for increased depth of field or to freeze fast motion. The
SAL1650 additionally features a circular aperture that, combined with
T
the F2.8 maximum aperture, contributes to beautiful defocusing effects.

Zoom range can be a very subjective and personal choice, hinging on
individual shooting style and preferred subjects. The 16–105mm range
