Optics

1.has built-in optical image stabilization
?

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. Show more

2.optical zoom
?

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

1.wide aperture (main camera)
?

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. Show more

3.Has rounded aperture blades
?

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.

Tamron 28-75mm f/2.8 Di III RXD
4.aperture blades
?

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
?

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.Has focus motor
?

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

Tamron 28-75mm f/2.8 Di III RXD
2.Can focus to infinity
?

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.

Tamron 28-75mm f/2.8 Di III RXD
3.minimum focus distance
?

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.

4.has a silent focus motor built into the lens
?

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.

Tamron 28-75mm f/2.8 Di III RXD
5.Has full-time manual focus
?

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.
