Olympus M.Zuiko ED 12-40mm F2.8 Pro: 22 facts and highlights
1. widest aperture at maximum focal length
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 full-time manual focus
With full-time manual focus you can move the focus ring whilst it is in AF (auto focus) mode. This means that you can make manual adjustments once the AF has finished, without changing to manual mode.

3. 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.

4. Weather sealed
Device is protected with extra seals to prevent failures due to any kind of weather.

5. 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.
6. Front element doesn't rotate
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.

7. 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.

8. 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.
9. Includes lens hood
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.

10. minimum focal length
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.
11. minimum angle of view
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).
12. Has a metal mount
A metal mount is generally superior to a plastic mount as it is more durable.

13. maximum focal length
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.
14. magnification
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.
15. smallest aperture at minimum 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.

17. weight
18. 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.
19. widest 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.
20. Is a normal lens
A normal lens is one that doesn't fall into another category such as wide angle or telephoto, and typically has a focal length between 35mm and 70mm. These lenses aren't tailored towards a specific type of photography, and so are quite versatile.

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