Opteka Camera Lenses
With Opteka camera lenses, you can pair your camera or camcorder with a lens that allows you to free up and broaden the types of photography you capture. These lenses are available as prime/fixed, which are affixed to the camera body, as well as zoom and specialty lenses that can be attached and removed from the camera as needed. These Opteka lenses are compatible with many different brands of digital cameras, including Nikon and Canon.
What's the difference between a telephoto lens and fish-eye lens?Two of the most common types of lenses provided by Opteka are fish-eye lenses and telephoto lenses. A telephoto model is equipped with a longer focal length than is normal, providing you with an image that's heavily magnified with a very narrow field of view. When you see a lens that offers a focal length of 100 millimeters or higher, this indicates that the model is a telephoto version.
As for fish-eye lenses, these are unique in that they offer an ultra-wide-angle image that captures a large field of view. Because of how wide the image is, a visual distortion is created that makes the photo appear to be spherical in nature. These types of lenses are oftentimes used for landscapes because of their ability to capture wide panoramic shots. Given the special nature of this lens type, it's also used to add flare to different photo types from portraits to action photography.
What types of cameras do Opteka lenses work with?Opteka lenses are compatible with many different types of cameras. Some of these lenses are compatible with mirrorless devices, which allow you to change the lens without requiring a DSLR device. A selection of these lenses is also compatible with specific camcorders, providing you with the means of capturing video with the addition of a unique lens.
The majority of Opteka lenses are compatible with both DSLR and SLR cameras, the former of which uses digital memory to store images while the latter consists of film that records the photos you capture. The different types of lenses that work with these cameras include fish-eye, telephoto, macro, wide-angle, and zoom lenses.
What's the difference between a manual and an autofocus lens?When you're selecting a lens, you'll discover that the lenses offered by Opteka come with manual focus, autofocus, or a combination of the two. Since some of these lenses provide you with just manual or autofocus, you should know which type to use and what the differences are between the two options. With manual focus, you control the focus of your camera by hand, adjusting the setting to your precise specifications.
If you've never handled manual focus settings before, the autofocus setting performs these tasks for you, intelligently focusing on an object in the image you're about to capture. Automatic shooting modes, such as this, make snapping images and manipulating light more convenient for the user. Manual focus lenses are commonly used by people who have experience with altering the focus settings on their own. Manual focusing is most commonly used with macro photography, action photography, and portraits for more precise images.
