The three-digit code on the surface of the lens is to indicate the year the lens was first released. (Since it is different from the year of manufacture, the release year and edition number may not match depending on the mount.)
* This product is developed, manufactured and sold based on the specifications of E-mount which was disclosed by Sony Corporation under the license agreement with Sony Corporation.

By assembling high-precision parts made of aluminum, TSC*1, and other materials, the lens achieves the high level of rigidity, durability, and build quality expected of the Art line without compromising portability. As a photographic tool, it offers the reliability needed for long-term use.
*1. TSC (Thermally Stable Composite) is a type of polycarbonate with a thermal expansion rate similar to that of aluminum. It has a high affinity to metal parts, which contributes to high quality product manufacturing.
The lens is equipped with an AFL button in two locations, which can be assigned to a range of functions via the menu on selected cameras. In addition to the aperture ring, the lens is equipped with an aperture ring lock switch*1 and a click switch to turn the click on and off.
*1. If you turn it on in position A, the aperture ring will be locked in position A. If you turn it on in a position other than A, it will be locked in the range from open to minimum aperture, and it will not be possible to turn it to position A.
In addition to a dust- and splash-resistant structure, the frontmost surface of the lens has a water- and oil-repellent coating applied, so that the lens can be used safely even in harsh outdoor environments.
*1. The product is designed to be dust- and splash-resistant but is not waterproof. When using the lens near water, etc., take care not to allow large amounts of water to splash on it. If water gets inside the lens, it may cause a major malfunction and render the lens unrepairable.




*Although this construction allows the lens to be used in light rain, it is not the same as being waterproof, so please prevent large amounts of water from splashing on the lens. It is often impractical to repair the internal mechanism, lens elements and electric components if they are damaged by water.
