General info

1.Front element doesn't rotate
Sigma APO 50-150mm F2.8 EX DC OS HSM
Sony 85mm F1.4 ZA Carl Zeiss Planar T*

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.

2.minimum focal length

50mm

85mm

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.

Best

Canon EF 35mm F/2 IS USM

0.24mm

3.maximum focal length

150mm

85mm

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.

Optics

1.has built-in optical image stabilization
Sigma APO 50-150mm F2.8 EX DC OS HSM
Sony 85mm F1.4 ZA Carl Zeiss Planar T*

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.

2.optical zoom

3x

1x

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

3.maximum angle of view

27.9°

29°

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).

4.minimum angle of view

9.5°

19°

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).

Best

5.magnification

0.16x

0.1x

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.

Aperture

1.widest aperture

f/2.8

f/1.4

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.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.

3.smallest aperture at maximum focal length

22f

22f

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
Sigma APO 50-150mm F2.8 EX DC OS HSM
Sony 85mm F1.4 ZA Carl Zeiss Planar T*

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.

5.aperture blades

9

9

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.Has full-time manual focus
Sigma APO 50-150mm F2.8 EX DC OS HSM
Sony 85mm F1.4 ZA Carl Zeiss Planar T*

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.

2.has a silent focus motor built into the lens
Sigma APO 50-150mm F2.8 EX DC OS HSM
Sony 85mm F1.4 ZA Carl Zeiss Planar T*

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.

3.Has focus motor
Sigma APO 50-150mm F2.8 EX DC OS HSM
Sony 85mm F1.4 ZA Carl Zeiss Planar T*

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

4.Can focus to infinity
Sigma APO 50-150mm F2.8 EX DC OS HSM
Sony 85mm F1.4 ZA Carl Zeiss Planar T*

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.

5.minimum focus distance

0.8m

0.8m

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.

3.transmission

3.2TStop

1.6TStop

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.

4.chromatic aberration

7µm

5.distortion

0.2%

0.2%

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.

6.vignetting

-0.8

-1.5

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.
