Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. Lens performance differs depending upon directions. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be. The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures. Built with convenience and ease-of-use in mind, you’ll be attracted by the compact size and thoroughly dazzled by the outstanding performance. You can share the use of a single polarizing (or other) filter and avoid the aggravation of searching through lens caps when changing lenses.

Small and light weight (the perfect match for mirrorless cameras) they are definitively portable and can easily be all carried together as a complete set that’s ready for every situation. Throughout the lineup you’ll find creative tools that help you enjoy the world of mirrorless cameras and a broader range of photographic possibilities.

The lens has the same 67mm filter diameter as the other members of the series of Tamron high-speed lenses for Sony E-mount cameras. Because the overall length does not change when focusing, you can get as close to an object as you need to without fear of accidentally bumping the front element. It’s comfortably portable, highly maneuverable and amazingly easy to use and compose. ![]() It has a very compact body, weighing just 215g (7.6 oz) and an overall length of 64mm (2.5 in).
