After you have decided on which digital camera to purchase, your next decison will be which lens to buy. There are a few things to consider before deciding which one is best for your Canon EOS digital camera.
There are a wide variety of Canon EOS lenses and which one is best for you depends on what type of photography you plan to do. If your main focus is portraits, then you’ll need a short telephoto lens, versus a wide angle lens for landscape photography. If you plan on taking high action photos, then you’ll want to buy a telephoto lens that is fast-focusing. One thing to keep in mind when deciding which one to buy is that lenses for canon EOS rebel generally have what some people call a focal length multiplier which is also known as the cropping factor. The cropping factor affects the size of the image through the lens, and depending on what size sensor your camera has will affect the field of view for that same lens.
Another aspect you’ll want to note when looking to buy Canon EOS camera lenses, is that there are two different lens mount designs depending on which EOS you have. EOS cameras manufactured before 2003 use the “EF” lenses. The newer style EOS digital camera made after 2003 uses the”EF-S” lenses and they can also use the older “EF” lenses. One way to see what lens your camera can use it to look at the lens mount. If your mount has just a red dot, then it will use an EF lens. If the mount has a red dot and a white square, then it can use either an EF or EF-S lens.
Some other things to consider when looking for a lens for your camera is how much you want to spend, do you want a new lens or used, what focal length range are you looking for and does it have to be a Canon lens or would you consider a compatible third party lens. Answering these questions will help you narrow down your choices so you can arrive at a better decision.
Choosing the best Canon EOS lenses for your particular needs can take a little time and research. There are many things to consider before you decide to invest your money in a lens that will probably be pretty costly. Doing the research now could save you time, money and frustration down the road.
