General info
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.weight
220g
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.
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.
4.weather-sealed (splashproof)
Tamron 20mm f/2.8 Di III OSD M1:2
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
5.Includes lens hood
Tamron 20mm f/2.8 Di III OSD M1:2
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.has or is a prime lens
Tamron 20mm f/2.8 Di III OSD M1:2
A prime lens has a fixed focal length. In general, these are sharper, with a wider aperture.
Optics
1.has built-in optical image stabilization
Tamron 20mm f/2.8 Di III OSD M1:2
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.
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).
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
0.5x
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.
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
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
Tamron 20mm f/2.8 Di III OSD M1:2
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.
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.
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
Tamron 20mm f/2.8 Di III OSD M1:2
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
Tamron 20mm f/2.8 Di III OSD M1:2
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
Tamron 20mm f/2.8 Di III OSD M1:2
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
Tamron 20mm f/2.8 Di III OSD M1:2
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.
