General info

1.Has a metal mount
Sigma 85mm F1.4 DG HSM Art
A metal mount is generally superior to a plastic mount as it is more durable.
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.
A longer maximum focal length allows you to focus in on a small part of a scene, and offers a narrower angle of view than shorter focal lengths.
4.Includes lens hood
Sigma 85mm F1.4 DG HSM Art
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.has or is a prime lens

A prime lens has a fixed focal length. In general, these are sharper, with a wider aperture.
6.Is a normal lens
Sigma 85mm F1.4 DG HSM Art
A normal lens is one that doesn't fall into another category such as wide angle or telephoto, and typically has a focal length between 35mm and 70mm. These lenses aren't tailored towards a specific type of photography, and so are quite versatile.

Optics

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

Aperture

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.
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.

Focus

1.Has focus motor

Lenses with a built-in focus motor can autofocus even if the camera does not have its own focus motor.
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.
3.Has full-time manual focus
Sigma 85mm F1.4 DG HSM Art
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.
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.
