Canon Lenses - Canon Telephoto Lens VS Canon Normal Lens
What's the difference between a Canon Telephoto Lens and a Canon Normal Lens? This
discussion is important to your knowledge of digital SLR cameras and the lenses that go with
them. But not only that, it is also important to know which lens will serve you best in a given
situation. Let's face, some folks buy a Canon digital SLR and never take the kit lens off. Nor do
they ever switch it off of the Auto mode (but that discussion is for a different day). If you are going
to improve as a photographer, it is incumbent upon you to know the capabilities of your camera
and the lenses and equipment that goes with it. A Canon normal lens is usually one of 35mm or
50mm, with 35mm being the focal length that most closely matches what can be seen by the
human eye without any enhancements. Since the days of 35mm film photography, this has been a
normal lens. More recently, digital photographers have been using the 50mm lens also as a
normal lens. But this also comes with an explanation. Full frame cameras, such as those in the
Canon "Mark" series have a sensor that produces the same size photo as a 35mm film camera.
But there are other digital SLR cameras that have smaller sensors. These are APS-C sensors,
and they produce images that are magnified when compared to the full-frame sensors. In fact,
they are magnified by a factor of 1.6x. With one of these cameras (a Rebel is a good example), a
50mm lens acts like a 80mm and is no longer normal. Likewise, a 35mm is more like a 56mm,
which also stretches the "normal" definition.
Telephoto is somewhat easier to explain and understand. A Canon telephoto lens is one that
magnifies the image so that it appears larger than what the human eye can see when standing in
the same spot as the camera. Basically, anything longer than 50mm is telephoto. In the case of a
crop sensor (APS-C) camera, 50mm is now telephoto, because, remember, it acts like the
equivalent of 80mm.
Canon telephoto lenses are considered medium telephoto up to about 200mm, after which they
are super telephoto.
By the way, it was once common that a lens was as long as the focal length designation. For
instance, a 200mm lens was physically 200mm long. Now, due to the way the sections of glass
are built into the housing of the lens, it is not longer necessary to them to be that long. This is quite
obvious when you look at some telephoto zoom lenses that do not physically extend when the
focal length is increased.
Speaking of zoom, there are many very popular Canon telephoto lenses that zoom in between
focal lengths. And some even zoom from wide angle to telephoto (passing through the "normal"
range as they do).
Now that you know what the difference is between the types of focal lengths, you need to decide
which focal length is best suited for your photography needs. Or, perhaps a zoom lens is best so
that you can cover a dynamic range of focal lengths as the needs change.
