The choices available to you, including those available from third-party manufacturers, can be quite extensive and confusing especially if you’re buying a new lens for the first time. However you only need to look into the following important features: focal length, aperture, image stabilization, format, and lens mount.

A telephoto lens is a type of long-focus lens wherein the focal length of the lens is longer than the physical length of the lens.

7. How do I differentiate prime lenses from zoom lenses?

Prime lenses have focal lengths or fields of view which are non-adjustable. This means that if you want to cover more or less of the subject or the landscape, you will need to actually get close or move away from the scene. On the contrary, zoom lenses are lens types with flexible focal lengths. Standard zoom lenses are used more for general shooting purposes, while wide angle zoom lenses can take in a much broader view of the landscape. Telephoto zoom and super zoom lenses allow you to get closer to your subject with their varying focal lengths.



8. Is it best to go for the best brand names when buying DSLR lenses?

In most cases, the brand of DSLR that you have will dictate the brand of lenses you will be buying. There are cheaper third-party DSLR lens makers and many of these lenses are built to be compatible with different lens mounts. Nonetheless you might want to do some research first before opting for these third-party manufacturers. A good brand name, such as Canon or Nikon, is almost always synonymous to excellence and quality.


9. If I have a Nikon or a Canon DSLR camera, am I limited to Nikon or Canon lenses, respectively?

In most cases, yes. This is due to the fact that most DSLR manufacturers have their own distinct, proprietary lens mounts, so that an interchangeable lens of a specific camera maker cannot be attached to the lens mount of another. Thus only a Nikon lens will be suitable for your Nikon camera. However Panasonic and Olympus have more flexible lens mounts, as they can accommodate lenses that fit into their Micro Four Thirds and Four Thirds mounts.

There are also third party lens makers, such as Sigma, Tokina, and Tamron, which manufacture lenses for different camera brands. Tokina for instance is known to develop and manufacture lenses for Nikon, Canon, and Pentax. Sigma makes lenses compatible with Canon, Nikon, Pentax, Sony, and Panasonic. Tamron sells different lenses which can be mounted on Canon, Nikon, Pentax, and Sony cameras.


10. What are the best names in DSLR lenses?

Some of the best names when it comes to DSLR lenses include Canon, Nikon, Carl Zeiss AG, Leica, Olympus, Panasonic, and Sony. For third-party lens makers, Sigma, Tokina, and Tamron are some of the most trusted names.
