5.has an optical viewfinder
Nikon D3100
Sony SLT-A99V + Sony SAL-55300

An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens sees. There is no time lag and they require no power - as opposed to electronic viewfinders which can drain battery life. They are also better in low light situations.

6.Has a built-in focus motor
Nikon D3100
Sony SLT-A99V + Sony SAL-55300

The focus motor moves the lens in order to autofocus. For system cameras, having a focus motor in the camera's body allows you to use a wide range of lenses, including lenses which do not have their own focus motor. For compact cameras, a focus motor is usually built-in.

Miscellaneous

1.Has focus motor
Nikon D3100
Sony SLT-A99V + Sony SAL-55300

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

2.Has rounded aperture blades
Nikon D3100
Sony SLT-A99V + Sony SAL-55300

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.

3.Has a metal mount
Nikon D3100
Sony SLT-A99V + Sony SAL-55300

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

4.Is a telephoto lens
Nikon D3100
Sony SLT-A99V + Sony SAL-55300

A telephoto lens allows you to zoom in on far away objects. This is particularly useful when you need to photograph a subject from a distance, such as wildlife photography, or even in some cases street photography where you can’t get near the subject.

5.Includes lens hood
Nikon D3100
Sony SLT-A99V + Sony SAL-55300

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.

6.Can focus to infinity
Nikon D3100
Sony SLT-A99V + Sony SAL-55300

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.
