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.

100mm F2.8 Macro SAL100M28
Doing macro photography outdoors “in the wild” often means that you
can’t get too close to your subject and lighting can’t be easily controlled.
That’s when you need a telephoto macro lens like the SAL100M28. Greater
working distance means you can capture tight macro shots of small-scale
wildlife without scaring it away, and you’re not so close that you need
special lighting to illuminate your subject. Of course the SAL100M28 is a first
class telephoto lens for normal shooting too, and can be a good choice for
portraits or other subjects that require a bit more reach than a normal lens.
