Wide angle
28mm F2.8 SAL28F28
28 millimeters is an extremely versatile focal length that can be useful in
a wide variety of situations on both full frame and APS-C format cameras.
On a 35mm full frame format camera, 28mm is wide enough to allow
comfortable shooting indoors or on the street without producing forced
perspective. On an APS-C format camera 28mm is equivalent to a focal
length of 42mm, which is close to “normal” in terms of angle-of-view and
perspective. For photo enthusiasts who use either or both types of bodies,
this lens is a must-have! It’s compact and lightweight, and is a versatile,
convenient choice for use either as a main or second lens.

DT 35mm F1.8 SAM SAL35F18
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!
• Weight (approx): 170 g
