General info

1.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.

2.has or is a prime lens
Canon EF 50mm F/1.4 USM
Canon EF 85mm F/1.8 USM

A prime lens has a fixed focal length. In general, these are sharper, with a wider aperture.

4.Is a normal lens
Canon EF 50mm F/1.4 USM
Canon EF 85mm F/1.8 USM

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.

5.maximum focal length

50mm

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.

6.Has a metal mount

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

Optics

1.optical zoom

1x

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.

2.magnification

0.15x

0.13x

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.

3.maximum angle of view

46°

30°

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).

Best

Leica APO-Summicron-SL 75mm f/2 ASPH

318°

4.minimum angle of view

46°

28°

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

1.widest aperture

f/1.4

f/1.8

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.

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.aperture blades

8

8

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.

4.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.

Focus

1.minimum focus distance

0.45m

0.85m

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.

2.Has focus motor
Canon EF 50mm F/1.4 USM
Canon EF 85mm F/1.8 USM

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
Canon EF 50mm F/1.4 USM
Canon EF 85mm F/1.8 USM

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
Canon EF 50mm F/1.4 USM
Canon EF 85mm F/1.8 USM

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.

5.Can focus to infinity
Canon EF 50mm F/1.4 USM
Canon EF 85mm F/1.8 USM

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.

Benchmarks

1.chromatic aberration

12µm

3µm

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.

2.sharpness result

10P-MPix

8P-MPix

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.

3.transmission

1.8TStop

2.1TStop

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.

5.distortion

0.2%

0.1%

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

-0.6

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.
