Tamron 35-100mm F / 2.8 Di III VXD (Sony E)(A078S)

Tamron 35-100mm F/2.8 Di III VXD (Sony E)(A078S)

Designed as a lighter and more compact alternative to the traditional 24-70mm f/2.8 zoom lens, this lens shifts the focus range towards portrait-friendly focal lengths. It covers a 35mm wide-angle to 100mm medium telephoto range, allowing you to shoot both ambient portraits and close-up isolations of subjects without having to switch lenses.

Despite its relatively small size, it maintains high optical performance with strong sharpness, smooth background blur, and consistent illumination, thanks to a constant f/2.8 aperture. The lens is built using Tamron's advanced optical design and a fast VXD linear motor autofocus system, ensuring fast, accurate, and quiet focusing for both stills and video.

It is especially designed for users who prioritize portability but still demand professional-quality images and flexibility in the standard and telephoto ranges.
