Excellent sharpness and contrast throughout the image
Circular aperture for attractive defocusing
Responsive internal SAM (Smooth Autofocus Motor) autofocus drive
Bright enough for handheld shooting in low light
35mm equivalent focal length: 52.5mm
There's a very good reason why 35mm is one of the most popular focal
lengths for use on APS-C format cameras. The full-frame equivalent
focal length is 52.5mm, providing "normal" perspective—similar to that
experienced with the naked eye—and an angle of view that is suitable
for an extremely wide range of subjects. You can shoot anything from
landscapes to portraits with this lens, without ever feeling that the
perspective is too forced or too flat, or that objects appear distorted. The
large F1.8 maximum aperture is another advantage: bright enough to
allow hand-held shooting in low light, and capable of producing smooth
defocusing effects that can add depth and artistic elegance to your
images. As a bonus, the SAL35F18 weighs a mere 170 grams, making it
unobtrusive on the camera, in a bag, or even in a pocket!

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
