The following chart presents a comparison between basic parameters of the new Sony and other instruments with similar parameters which are, additionally, designed for mirrorless cameras with smaller sensors.

Small physical dimensions of the tested lens are really worth noticing, especially if you compare it to such instruments as the Zeiss Touit. The Sony is handier in every respect even though its aperture is faster and its focal length - shorter. It can be compared only to the new Panasonic, a lens with a better aperture fastness but also a noticeably narrower angle of view.

In the photo below the Sony E 11 mm f/1.8 is positioned between two lenses designed for APS-C sensors – the Samyang 12 mm f/2 on the left and the Sigma C 30 mm f/1.4 DC DN on the right.

The tested lens starts with a metal mount that surrounds contacts and a rear element, 18 mm in diameter, that doesn't move. The element is situated just 1-2 mm below a black ring made of plastic that fills the area between the element and the contacts. From this side everything looks well and the instrument seems to be weather-sealed.

The proper body of the lens is made of black plastics starts with a smooth, immobile ring. On the ring you can find a white dot, making an alignment with a camera easier, the mount type (E-mount), the lens's serial number along with information that it was produced in China.

The ring's diameter increases as you move further away from the mount and that enlargened part features an inscription 'E 1.8/11', the producer's logotype, a round Focus Lock button and an AF/MF switch.

A manual focus ring, as wide as 17 mm, is another part of the lens. It is a focus-by-wire construction without any distance or depth-of-field scale. Its focus throw amounts to an angle of about 130 degrees, a satisfactory value, allowing you precise settings.

Further on you find a narrow, metal ring that turns into a hood mount. The front element is convex, 28 mm in diameter, and immobile. It is surrounded by an inscription with the name and parameters of the lens along with a non-rotating filter thread, 55 mm in diameter.

When it comes to optical construction you deal here with 12 elements positioned in 11 groups, three aspherical elements and three made of low dispersion ED glass among them. Inside you can also find an aperture with seven blades that can be closed down to a value of f/16 at the maximum.

Buyers get in the box with the lens: both caps and a hood.
