DT 30mm F2.8 Macro SAM SAL30M28

If you shoot with an APS-C format camera and want a lightweight,
compact lens that will handle snapshots and portraits plus macro
photography as well, this is it. The 35mm equivalent focal length of this
lens is a distinctly “normal” 45mm, making it a good choice for general
photography. But when an exquisite little detail catches your eye, you can
move in as close as 2 centimeters from your subject to capture macro
images with up to 1:1 magnification. The details you focus on will be
astonishingly sharp, while the out-of-focus background dissolves into a
creamy blur that can really make the details stand out. The SAL30M28 is
only 45 millimeters long and weighs a discreet 150 grams, so it can stay
on your camera or in your bag at all times without getting in the way.

50mm F2.8 Macro SAL50M28

Photographers who are attracted to details need a lens that lets them
get in close when necessary, filling the frame with their diminutive but
fascinating subjects. A lens like the SAL50M28, with a minimum focusing
distance of just 20 centimeters and up to 1:1 magnification, can open
up a world of creative possibilities. But there’s no need to change
lenses when you want to go back to shooting at normal distances.
The SAL50M28 offers outstanding optical performance for general
photography as well, and its 50mm focal length is a very versatile choice
for 35mm full frame format cameras. On APS-C format cameras you get a
little more reach, which can be advantageous for some normal subjects
as well as macro shooting.
