Bright, F1.8 maximum aperture and 50mm focal length (35mm-format
equivalent: 75mm) - With a maximum aperture of F1.8, the DT 50mm F1.8 SAM
delivers outstanding image quality in a wide range of shooting situations.
And because the aperture range extends from F1.8 to F22, it provides you
with expanded control over depth of field and dynamic expression. As a
result, it offers a valuable of range of photographic expression that goes
beyond what you can experience with standard zoom lenses. In addition, the
DT 50mm F1.8 SAM’s large maximum aperture setting can be used in
tandem with your camera body’s integrated SteadyShot™ image
stabilization to assure excellent low-light shooting performance.

portability and operability that make it an ideal introductory-level
portrait lens for ? DSLRs with an APS-C type sensor.

circular aperture mechanism assures smooth background defocusing when
shooting at larger apertures, making subjects stand out from the background
more prominently when shooting portraits.
High contrast, resolution, and image quality - The DT 50mm F1.8 SAM is an
ideal choice for first-time fixed focal length lens buyers. In addition to
excellent colour balance, it offers crisp, natural imaging across the focal
plane, with high contrast and resolution even at the periphery of the image

exceptionally clear imaging and a range of expression that is distinctly
different from lenses like the a DT 18-55mm F3.2-5.6 SAM zoom.
Newly-developed Smooth Autofocus Motor (SAM) for smooth AF operation - The
DT 50mm F1.8 SAM’s focusing lens group is driven by a new Smooth
Autofocus Motor (SAM) in the lens itself, instead of a motor in the camera
body. Responding instantly to AF drive control signals from the camera, the
motor delivers power with smoothness and precision.
0.34m minimum focusing distance, 0.2 maximum magnification ratio - At
0.34m, the DT 50mm F1.8 SAM has one of the shortest minimum focusing
distances in its class, with a maximum magnification ratio of 0.2x that
