Some of these lenses come with fixed focal lengths while others are outfitted with zoom lengths that allow you to change between numerous focal lengths like 18-270mm.

Make sure that you have one of these compatible types of devices when selecting Tamron camera lenses for Canon cameras:

• Digital single-lens reflex (DSLR): This is a type of digital camera that supports interchangeable lenses and is equipped with an array of automatic and manual settings, many of which allow you to switch between both modes. These DSLR cameras usually store the photos and video that you capture on memory cards, hard disk drives, or solid state drives.
• Mirrorless: This is a type of camera that comes with a digital sensor and can accommodate interchangeable lenses. These cameras do not consist of a mirror system within the body of the camera, which allows them to have a compact form.

Three focus types are available on these Tamron camera lenses:

• Auto: This is a focus system that is controlled by a small motor and the camera sensor in order to focus the lens automatically before you take a picture. While the subject of a photo can be identified manually or automatically, the autofocus system will zoom in on this subject without requiring you to change any additional settings.
• Manual: This is a type of focus system that requires you to change the focus of the lens by hand. The focus ring can commonly be found around the middle of the lens.
• Auto/Manual: Certain lenses and cameras are compatible with autofocus and manual focus systems, providing you with the ability to switch between both depending on your preference. The switches used to change between modes can usually be found on the sides of these lenses.

The aperture of macro lenses refers to how much light is let in when the shutter closes upon taking a picture, which determines the exposure of the photo. An aperture amount is represented by an f-stop that is followed by a number, such as f/3.4. Smaller numbers indicate maximum apertures while larger numbers like f/22 display minimum apertures. A maximum aperture lets in a large amount of light due to the shutter being more open. A minimum aperture lets in a small amount of light. The maximum apertures available with these lenses can extend from f/1.8 to f/6.3.
