DT 16–50mm F2.8 SSM SAL1650
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
the F2.8 maximum aperture, contributes to beautiful defocusing effects.

Mid-range zoom
DT 16–105mm F3.5–5.6 SAL16105
Zoom range can be a very subjective and personal choice, hinging on
individual shooting style and preferred subjects. The 16–105mm range
of this lens is a “sweet spot” for many photographers, wide enough at
the 16mm end to capture indoor scenes and long enough at 105mm
to fill the frame with relatively distant subjects. Comfortable handling is
another plus, facilitated by a compact, lightweight design and an auto-
clutch mechanism that prevents focus ring rotation during autofocus
operation, so you can comfortably cradle the lens in your hand while
shooting. Of course comfort isn’t everything. A precision optical design
delivers superb image quality throughout the entire zoom range.
