Sigma Camera Lenses for Canon

Sigma camera lenses for Canon cameras allow you to capture various types of photographs. Sigma lenses for Canon cameras are available in both fixed and zoom lens types, such as DSLR, HSM, Pentax, and telephoto, allowing you to select the type that matches your preference and discount any settings that you may not need for every photo set-up. These Sigma lenses can be fitted onto a wide array of optical mounts, ranging from the Canon EF to the Canon EOS.

What are some available focal lengths?

When you are selecting one of these lens models by Sigma, including DG, or full frame, you will have many lengths to choose from. This number indicates the distance between the lens and the image sensor at the point where the image is in focus. When selecting one of these models, you will notice that some are available with a fixed length while others provide you with varying lengths to which you can set the distance. These fixed and zoom lenses primarily come in variations of 50-millimeters and 70 to 300 millimeters. Although the aforementioned are the most common types available among these models, you can find Sigma lenses that offer 8 millimeters to more than 600 millimeters in focal length.

What does the aperture of a lens refer to?

Whether you just started to get interested in photography or have been taking photos for years, one of the most important components of the lens from Sigma is its aperture, which is a number that is signified by an f/number, such as f/1.8. This indicates the ratio of the focal length when compared to the diameter of the aperture. In most lens models, you are provided with the option of altering the minimum and maximum aperture to the micro or macro settings you desire. As you change this setting, you alter how much light is allowed through the lens. The lower the number, the greater the opening in the Sigma lens, which means that more light is let through. When the number is higher, the opening can be very small, letting a small amount of light into the image that you are about to take.

What are the different types of focusing in a lens?

When attempting to zoom in or out on an image, the Sigma lenses on a camera provide you with the means of honing in on any object in the frame:

  • Manual: This type of focusing indicates that the user of the device must change the focus settings on their own, providing them with full control over how the image turns and posts, which allows for a substantial amount of precision.
  • Autofocus: When lenses have been outfitted with autofocus technology, this means that the model is equipped with a small motor that allows it to hone in automatically on a point or area within the frame that may stand out. For instance, it will automatically detect when a person is in a photo and focus on them.
  • Auto/manual: Most of these models come with dual functionality that provides you with both auto and manual focusing so that you can use whichever setting you prefer for each specific situation.
