Normal
50mm F1.4 SAL50F14
50mm focal length with a maximum aperture of F1.4: this quintessential
fast “normal” lens formula has produced some of the greatest
photographic masterpieces in history, and continues to serve as a
photographic standard to this day. Of course not all 50mm F1.4 lenses
are created equal, and the stunning clarity and contrast delivered
by the SAL50F14 proves that it is one of the finest in its class. While the
in-focus plane is sharp from corner to corner, the combination of F1.4
maximum aperture and circular aperture design makes it possible to elicit
silky-smooth defocusing effects to enhance dimensionality and isolate
important visual elements. This is a lens that should be part of every
serious photo enthusiast’s palette.

DT 50mm F1.8 SAM SAL50F18
On APS-C format cameras, for which it is specifically designed, the
SAL50F18 functions as a moderate telephoto lens (equivalent to 75mm on
a full-frame camera) that can be ideal for shooting portraits as well as for
framing and isolating areas of interest in broader, busier scenes. Not only
can you isolate the desired subject matter by framing, but you can also
take advantage of the lens’s large F1.8 maximum aperture and circular
aperture design to isolate your subject from the background by using
defocusing. The large maximum aperture also facilitates shooting in low
light, a capability that is further enhanced by SteadyShot INSIDE™ image
stabilization featured in a series bodies.
