General info

1.Has a metal mount
Sigma 70mm f/2.8 DG Macro Art
Tamron SP 90mm F2.8 Di Macro 1:1 VC USD
A metal mount is generally superior to a plastic mount as it is more durable.
2.weather-sealed (splashproof)
Sigma 70mm f/2.8 DG Macro Art
Tamron SP 90mm F2.8 Di Macro 1:1 VC USD
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
3.minimum focal length

70mm

90mm

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.weight

515g

610g

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
5.maximum focal length

70mm

90mm

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.
6.Includes lens hood
Sigma 70mm f/2.8 DG Macro Art
Tamron SP 90mm F2.8 Di Macro 1:1 VC USD
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.

Optics

1.has built-in optical image stabilization
Sigma 70mm f/2.8 DG Macro Art
Tamron SP 90mm F2.8 Di Macro 1:1 VC USD
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.maximum angle of view

34.3°

27°

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).
3.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.
4.magnification

1x

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.
5.minimum angle of view

34.3°

17.6°

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).

Aperture

1.wide aperture (main camera)

f/2.8

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.widest aperture at maximum focal length

2.8f

2.8f

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 70mm f/2.8 DG Macro Art
Tamron SP 90mm F2.8 Di Macro 1:1 VC USD
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

9

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.
5.smallest aperture at maximum focal length

22f

32f

A smaller aperture reduces the amount of light reaching the sensor. This is important in bright conditions where a wider aperture could result in your image being overexposed. Another advantage is that with a smaller aperture you get a greater depth of field, and can keep all of the image in focus.
6.smallest aperture at minimum focal length

22f

32f

A smaller aperture reduces the amount of light reaching the sensor. This is important in bright conditions where a wider aperture could result in your image being overexposed. Another advantage is that with a smaller aperture you get a greater depth of field, and can keep all of the image in focus.

Focus

1.Can focus to infinity
Sigma 70mm f/2.8 DG Macro Art
Tamron SP 90mm F2.8 Di Macro 1:1 VC USD
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.
2.Has focus motor
Sigma 70mm f/2.8 DG Macro Art
Tamron SP 90mm F2.8 Di Macro 1:1 VC USD
Lenses with a built-in focus motor can autofocus even if the camera does not have its own focus motor.
3.has a silent focus motor built into the lens
Sigma 70mm f/2.8 DG Macro Art
Tamron SP 90mm F2.8 Di Macro 1:1 VC USD
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.
4.Has full-time manual focus
Sigma 70mm f/2.8 DG Macro Art
Tamron SP 90mm F2.8 Di Macro 1:1 VC USD
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.
5.minimum focus distance

0.26m

0.3m

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.
