The SAL35F14G, with its superb optics and large F1.4 maximum aperture, is one of the finest fast 35mm lenses in its class. In addition to no-compromise G Lens construction and quality throughout, it features an optical design that includes an aspherical lens element that contributes to consistently superior, low-distortion image quality right up to the F1.4 maximum aperture. You can shoot wide open in low light knowing that the entire scene will be captured with equally superb clarity and contrast.The large maximum aperture and circular aperture design are also an advantage when you want to isolate your subject from a busy background, for example, allowing you to defocus unwanted detail so your subject stands out. • Weight (approx): 510 g • Dimensions (Dia. x L): 69 x 76 mm • Max. magnification ratio: 0.2x 44 Telephoto prime 300mm F2.8 G SAL300F28G S mode, 1/80 sec., F14, ISO 100, Flash; Photo: Nick Webster Three ED glass elements effectively suppress aberration Exceptional sharpness and contrast throughout the image area SSM (Super Sonic wave Motor) for fast, quiet autofocus operation Circular aperture for attractive defocusing Focus hold and focus range switches offer precision focusing control ED glass At 300 mm 100 80 60 40 20 0 4 8 12 16 20 Distance from center of image (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 If you're serious about shooting sports, nature, or wildlife, or just about any subject that moves and needs to be shot from a distance, this is a lens that you'll want to have in your kit. 300mm is the sweet spot for a wide range of telephoto applications, and its large F2.8 maximum aperture makes it possible to use motion-stopping shutter speeds when shooting fast action, as well as to control depth-of-field for creative defocusing. Chromatic aberration can be a problem in telephoto lenses, but the SAL300F28G uses three ED elements in a top-class optical design that reduces aberration to a minimum, ensuring high resolution, high contrast image quality at all aperture settings. A minimum focusing distance of just 2 meters is another advantage that is rare in a lens of this type, letting you take advantage of telephoto characteristics at close range. • Weight (approx): 2310 g • Dimensions (Dia. x L): 122 x 242.5 mm • Max. magnification ratio: 0.18x • Tripod mount supplied 45
