General info

1.minimum focal length

12mm

105mm

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.

2.maximum focal length

100mm

105mm

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.

3.Front element doesn't rotate

Sigma 105mm F2.8 EX DG OS HSM Macro

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.

4.Has a metal mount

Sigma 105mm F2.8 EX DG OS HSM Macro

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

5.Includes lens hood
Olympus M.Zuiko Digital ED 12-100mm F4.0 IS Pro
Sigma 105mm F2.8 EX DG OS HSM Macro

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.Is a macro lens

Sigma 105mm F2.8 EX DG OS HSM Macro

A macro lens is used to take very close-up photos, allowing you to capture flowers, insects etc. in great detail. A macro lens is any lens with 1:1 magnification.

Optics

1.has built-in optical image stabilization

Sigma 105mm F2.8 EX DG OS HSM Macro

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

1x

1x

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

3.magnification

0.3x

1x

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

f/2.8

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.

2.Has rounded aperture blades

Sigma 105mm F2.8 EX DG OS HSM Macro

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.aperture blades

7

9

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
Olympus M.Zuiko Digital ED 12-100mm F4.0 IS Pro
Sigma 105mm F2.8 EX DG OS HSM Macro

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
Olympus M.Zuiko Digital ED 12-100mm F4.0 IS Pro
Sigma 105mm F2.8 EX DG OS HSM Macro

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
Olympus M.Zuiko Digital ED 12-100mm F4.0 IS Pro
Sigma 105mm F2.8 EX DG OS HSM Macro

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 105mm F2.8 EX DG OS HSM Macro

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

0.15m

0.31m

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.
