General info

1.maximum focal length

300mm

400mm

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.

2.Is a wide angle lens
Sigma 18-300mm F/3.5-6.3 DC Macro OS HSM
Tamron 18-400mm f/3.5-6.3 Di II VC HLD

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

For example

Tamron SP 15-30mm f/2.8 Di VC USD G2

3.minimum focal length

18mm

18mm

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.

4.Weather sealed
Sigma 18-300mm F/3.5-6.3 DC Macro OS HSM
Tamron 18-400mm f/3.5-6.3 Di II VC HLD

Device is protected with extra seals to prevent failures due to any kind of weather.

5.Front element doesn't rotate
Sigma 18-300mm F/3.5-6.3 DC Macro OS HSM
Tamron 18-400mm f/3.5-6.3 Di II VC HLD

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.

6.Has a metal mount
Sigma 18-300mm F/3.5-6.3 DC Macro OS HSM
Tamron 18-400mm f/3.5-6.3 Di II VC HLD

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

Optics

1.has built-in optical image stabilization
Sigma 18-300mm F/3.5-6.3 DC Macro OS HSM
Tamron 18-400mm f/3.5-6.3 Di II VC HLD

Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.

2.optical zoom

16.6x

22.2x

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

3.maximum angle of view

7.6°

75.5°

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°

4.magnification

3x

0.34x

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.

Best

Leica Vario-Elmarit-SL 24-90mm F2.8-4 ASPH

14x

5.minimum angle of view

5.4°

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

Aperture

1.widest aperture

f/3.5

f/3.5

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.

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.Has rounded aperture blades
Sigma 18-300mm F/3.5-6.3 DC Macro OS HSM
Tamron 18-400mm f/3.5-6.3 Di II VC HLD

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.

4.aperture blades

7

7

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
Sigma 18-300mm F/3.5-6.3 DC Macro OS HSM
Tamron 18-400mm f/3.5-6.3 Di II VC HLD

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 a silent focus motor built into the lens
Sigma 18-300mm F/3.5-6.3 DC Macro OS HSM
Tamron 18-400mm f/3.5-6.3 Di II VC HLD

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 focus motor
Sigma 18-300mm F/3.5-6.3 DC Macro OS HSM
Tamron 18-400mm f/3.5-6.3 Di II VC HLD

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

4.Can focus to infinity
Sigma 18-300mm F/3.5-6.3 DC Macro OS HSM
Tamron 18-400mm f/3.5-6.3 Di II VC HLD

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.

5.minimum focus distance

0.38m

0.45m

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.
