Take Beautiful Photos in All Kinds of Settings with a Sigma 30mm Canon Lens

Anyone with aspirations of becoming a photographer of any acclaim knows you'll need some good equipment. While most pieces a step above a disposable camera can produce good results, it won't matter how good your camera itself is if you don't have the right lens. For this, try a Sigma 30mm Canon camera lens for capturing a variety of different types of settings from a unique viewpoint.

While you could potentially take any kind of picture you wanted with any type of lens, it's common knowledge that certain sized lenses are better for certain jobs. The 30mm lens, for example, has a slightly smaller focal length than the standard 35mm lens. As a result, they are classified as "wide-angle lenses" for the way they stretch the edges of the frame. This makes them ideal for things like photographing landscapes or images with a wide range of subjects, as the distortion caused by a 30mm lens appears somewhat naturalistic while also letting the photographer capture more of the image than they would be able to with a larger focal-length lens. This is all especially true for the 30mm, as it is only a small difference from the 35mm standard. A list of potential shoots could include:

• Large family photos: Rather than the standard lens used for photographing one person, a 30mm lens would be useful in capturing everyone in a large gathering.
• Street photography: Photographing streets or other urban areas is made easier with wide-angle lenses as they allow you to take in more details in a single shot.
• Ocean pictures: When capturing large swaths of ocean or bodies of water, 30mm lenses are an effective choice.

Many of the 30mm lenses produced by Sigma for Canon cameras do have an auto-focus feature. This can be turned on or off in certain models in conjunction with the controls on the camera itself. To be sure whether or not a particular lens has this feature, be sure to read the eBay listing carefully and, if in doubt, check the manufacturer's website for additional details.

A lens' f-number refers to the ratio between the focal length and the pupil, essentially giving you a number to assign to the aperture based on its size. As such, the maximum aperture on most Sigma 30mm lenses is f1.4, and the minimum aperture on these lenses is f16. While there may be variations available, this is the standard for the majority.
