Sigma EX 4,5mm f/2,8 DC HSM Fisheye Review

Name: Sigma EX 4,5mm f/2,8 DC HSM Fisheye
Brand: Sigma
Rating: 3 (1 reviews)

General information

This is a prime lens manufactured by Sigma and the model was launched 2007.
The lens belongs to the category wide angle prime lenses, a wide angle lens where you do not have the possibility to zoom in and out.
Worth thinking about is that the lens has a Fisheye-character which give the images an extreme wide but curved 'barrel' look which may require some post processing in your image editing software. Though, the lens offers you as a photographer the widest of wide angle views..

Compatibility, autofocus and focal length

The lens is available for both Canon and Nikon cameras, but there are two different versions of this lens (one for each brand and mount) so it is important that you ask for and choose the right version when bying the lens.

This lens is designed and meant for Canon and Nikon cameras with a smaller sensor (often referred to as 'APS-C') which means that the lens does not fit all camera models. By clicking on the link below you can make sure that the lens works with your camera model and you should do an additional check with your local dealer as well, before you buy the lens just to be sure.

The ability to use autofocus is available for all cameras.

The lens has a focal length of 4 mm. Since the lens is designed to be used on a camera with smaller sensor ('APS-C') the focal length will be equivalent to 6 mm if you have a Canon camera or 6 mm if you have a Niko camera.

Lens brightness and image stabilizer

The lens brightness and aperture value is f/2,8.

This aperture value indicates that the lens is very bright. This will make it so much easier shooting in darker environments where you do not want or can use flash lighting, for example in churches or at different sports venues.

The lens lacks image stabilization, which otherwise os good for avoiding the blur that can occur when using slow shutter speeds. Since the lens is bright, with good aperture value, the lack of image stabilization might not be that big of a deal, although a image stabilizer is always an advantage to have.

Filter and Lens Hood

The lens has a built-in filter holder which means that you at the rear of the lens (towards the camera) can place a filter, but an opportunity to protect the front lens with a filter does not exist.

Unfortunately there is no lens hood included when buying the lens.
