35mm prime lenses are a staple for many photographers. The angle of
view provided by this focal length is one of the most comfortable and
versatile on both 35mm full frame format and APS-C format cameras, and
with that, this lens can be used for anything from close-ups to landscapes.
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
20
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.

range of telephoto applications, and its large F2.8 maximum aperture
