Canon EF 300mm F2.8L IS II USM vs Sigma 10-20mm F3.5 EX DC HSM: 33 facts in comparison

1. 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.

2. chromatic aberration

The lateral chromatic aberration result from the DxOMark set of metrics. Chromatic aberration is a type of distortion which results in color fringing along edges within the image. Tested with Nikon D7000 or Canon 7D. Source: DxOMark.

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. sharpness result

The sharpness result from the DxOMark set of metrics. This result is based on the MTF (modulation transfer function) measurement, and gives an overall indication of the sharpness of images produced by the lens. Tested with Nikon D7000 or Canon 7D. Source: DxOMark.

6. 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.

7. 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.

8. transmission

The transmission result from the DxOMark set of metrics. Transmission refers to the amount of light that reaches the sensor through all of the glass elements of a lens, with a lower TStop signifying more light. This is important as less light reaching the sensor can lead to the requirement of higher ISOs or slower shutter speeds. Tested with Nikon D7000 or Canon 7D. Source: DxOMark.

9. DxOMark score

DxOMark is a set of tests to measure the performance and quality of lenses and cameras. The DxOMark score is the overall score given to the lens. Tested with Nikon D7000 or Canon 7D. Source: DxOMark.

11. 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.

13. distortion

The distortion result from the DxOMark set of metrics. Distortion in the lens refers to the variation of magnification throughout the image. More distortion will result in straight lines being recorded incorrectly in the image. Tested with Nikon D7000 or Canon 7D. Source: DxOMark.

14. 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.

17. 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.

18. 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.

19. Has a metal mount

A metal mount is generally superior to a plastic mount as it is more durable.

20. 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.

21. 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.

22. 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.

23. vignetting

The vignetting result from the DxOMark set of metrics. Vignetting refers to when the brightness of an image changes from the center towards the edges, resulting in darkened corners. A result of 0 is perfect and the image will have no vignetting. Tested with Nikon D7000 or Canon 7D. Source: DxOMark.

24. 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.
