2.Has a metal mount
?

A metal mount is generally superior to a plastic mount as it is more durable.

3.has or is a prime lens
?

A prime lens has a fixed focal length. In general, these are sharper, with a wider aperture.

Sony E 20mm F2.8
4.Includes lens hood
?

It comes with a lens hood so that you don’t have to buy it separately. These are used to block strong light sources, such as the sun, from the lens to prevent glare and lens flare.

5.minimum focal length
?

A shorter minimum focal length allows you to get more of the scene in the photo, and offers a wider angle of view than longer focal lengths.

6.Front element doesn't rotate
?

The front element doesn’t rotate. This is important if you use filters, as some such as polarising or gradient filters have to be orientated a certain way.

Optics

1.maximum angle of view
?

At the shorter end of the lens you get the widest angle of view. This allows you to fit more of the scene into the photograph (based on APS-C format).

2.minimum angle of view
?

At the longest end of the lens you get the narrowest angle of view. This allows you to fit a small portion of the scene into the photograph, such as when you are zooming in on a subject (based on APS-C format).

3.magnification
?

A true macro lens has a magnification of 1:1. This means that the image produced is a life-size representation of the subject being photographed.

4.optical zoom
?

The zoom range is the ratio between the longest and shortest focal lengths. A higher zoom range means that the lens is more versatile.

Aperture

1.widest aperture at maximum focal length
?

With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.

3.smallest aperture at maximum focal length
?

A smaller aperture reduces the amount of light reaching the sensor. This is important in bright conditions where a wider aperture could result in your image being overexposed. Another advantage is that with a smaller aperture you get a greater depth of field, and can keep all of the image in focus.

5.aperture blades
?

The aperture controls how much light gets through to the camera’s sensor. More blades is often an indicator of a better quality lens. It also allows you to achieve much nicer looking bokeh when blurring out your background, whereas a lens with less blades will often produce harsher, more polygonal bokeh.

6.Has rounded aperture blades
?

Similar to the number of aperture blades, rounded blades affect the way the light gets through to the sensor. Rounded blades, often only found on more expensive lenses, improve the appearance of the out-of-focus areas. This allows you to attain better, softer looking bokeh in your photos.

Focus

1.Can focus to infinity
?

Many lenses allow you to focus to infinity. This is essential when you wish to take photos including far off objects, such as when shooting landscapes, in order to make sure everything is sharp and in focus.

Sony E 20mm F2.8
2.Has focus motor
?

Lenses with a built-in focus motor can autofocus even if the camera does not have its own focus motor.

Sony E 20mm F2.8
3.minimum focus distance
?

This is the closest distance that the lens can focus. A shorter minimum focus distance allows you to get closer to your subject, and is particularly important when doing macro photography.

4.Has full-time manual focus
?

With full-time manual focus, you can move the focus ring whilst it is in AF (autofocus) mode. This means that you can make manual adjustments once the AF has finished, without changing to manual mode.

Sony E 20mm F2.8
5.has a silent focus motor built into the lens
?

Lenses with built-in focus motor focus faster and more quietly than lenses without a focus motor which rely on the camera's body focus motor.
