General info

1.Front element doesn't rotate
Pentax smc DA 16-45mm F4.0 ED AL

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.

2.maximum focal length

45mm

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.

Best

Sigma 300-800mm F5.6 EX DG APO HSM

800mm

3.minimum focal length

16mm

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.

Best

Canon EF 35mm F/2 IS USM

0.24mm

4.Is a wide angle lens
Pentax smc DA 16-45mm F4.0 ED AL

A wide angle lens is great for capturing larger areas of a scene, such as when doing architectural or landscape photography.

5.Has a metal mount

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

Optics

1.optical zoom

2.8x

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

Best

Tamron 18-400mm f/3.5-6.3 Di II VC HLD

22.2x

2.maximum angle of view

83°

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).

Best

Leica APO-Summicron-SL 75mm f/2 ASPH

318°

3.minimum angle of view

53°

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).

Best

Tamron SP 150-600mm F/5-6.3 Di VC USD

4.magnification

0.26x

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

1.widest aperture

f/4

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.

Best

Samyang XP 50mm f/1.2

f/1.2

2.widest aperture at maximum focal length

4f

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.

Best

Samyang XP 50mm f/1.2

1.2f

3.aperture blades

6

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 full-time manual focus
Pentax smc DA 16-45mm F4.0 ED AL

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.

2.Has focus motor
Pentax smc DA 16-45mm F4.0 ED AL

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

3.minimum focus distance

0.28m

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.

Best

Zeiss Batis 40mm f/2 CF

0.02m

4.Can focus to infinity
Pentax smc DA 16-45mm F4.0 ED AL

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.
