General info

1.Has a metal mount
Sigma 30mm F2.8 DN A
Sony E 30mm F3.5 Macro
A metal mount is generally superior to a plastic mount as it is more durable.
2.weight

140g

138g

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.
3.has or is a prime lens
Sigma 30mm F2.8 DN A
Sony E 30mm F3.5 Macro
A prime lens has a fixed focal length. In general, these are sharper, with a wider aperture.
4.Is a macro lens
Sigma 30mm F2.8 DN A
Sony E 30mm F3.5 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.
5.Includes lens hood
Sigma 30mm F2.8 DN A
Sony E 30mm F3.5 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.
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.

Optics

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

Aperture

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.
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.
4.Has rounded aperture blades

Sony E 30mm F3.5 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.
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.
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.Can focus to infinity

Sony E 30mm F3.5 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.
2.Has focus motor
Sigma 30mm F2.8 DN A
Sony E 30mm F3.5 Macro
Lenses with a built-in focus motor can autofocus even if the camera does not have its own focus motor.
3.Has full-time manual focus
Sigma 30mm F2.8 DN A
Sony E 30mm F3.5 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.
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.
