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. • Weight (approx): 295 g • Dimensions (Dia. x L): 71.5 x 60 mm • Max. magnification ratio: 1.0x 38 P mode, 1/160 sec., F2.8, ISO 400, Auto white balance; Photo: Kentaro Fukuda Macro 100mm F2.8 Macro SAL100M28 Stunning macro shots from a comfortable distance Autofocus from 1:1 magnification to infinity Double floating design contributes to outstanding close-up image quality 9-blade circular aperture for attractive defocusing Focus hold button, focus range limiter Focus ring with auto clutch does not rotate during autofocus At 100 mm 100 80 60 40 20 0 3 6 9 12 20 Distance from optical center of lens (mm) Spatial frequency Max. aperture R T 10 line pairs/mm F8 aperture R T 30 line pairs/mm R: Radial values T: Tangential values 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. • Weight (approx): 505 g • Dimensions (Dia. x L): 75 x 98.5 mm • Max. magnification ratio: 1.0x 39
