If you think that finding a good SLR camera is tough, try to find the
best digital SLR lens to go with it. If you felt there were plenty of
cameras to choose from, the number of available lenses is going to be
overwhelming. Digital SLR lenses come in all manner of shapes and sizes,
and vary massively in price.By simply changing a lens, the scope of a
potential image changes, too. Understanding the difference between
lenses will help you get the best shot. Some are built for the demanding
needs of professionals and others are just right for the everyday
snapshot photographer. Faced with all these alternatives, what’s a
newcomer to the world of SLR photography to do?
Just follow the 6 steps that I outline below and you’ll find your way to the best digital SLR lens for your camera.
1. Find Your Focal Length
Before
I get too far into my discussion of focal length, I’d like to provide
you with a definition of the term. Focal length is measured in
millimeters (mm) and it represents the distance from the optical center
of a lens to the digital camera sensor when the subject of the photo is
in focus. That’s the textbook definition, but it really doesn’t explain
too much about why focal length is useful.
Here’s the plain-English translation:
* With a short focal length you have to be close to your subject for a close-up
* With a long focal length you can be far away and still get a close-up
* A zoom lens has a variable focal length
* A prime lens has a fixed focal length.
How do you decide which focal length lens you need? It all comes down to what you want to photograph.
2. Prime and Zoom Lenses
Step
two on your path toward finding the best DSLR lens requires a decision
between prime and zoom lenses. Since you’ve already made up your mind
about what focal length you’d like, choosing between prime and zoom is
further narrowing the field of digital SLR lens options. Each lens type
has advantages. The decisions that you make about which kind to get will
depend a lot on what sorts of pictures you want to take with the lens:
clearly, a gigantic heavy zoom lens is not going to be your best option
if you’d like to travel with your camera.
3. The Importance of Maximum Aperture
The
maximum aperture of the lens you choose can have a significant impact
on the types of photos you can take with your digital SLR camera.
However, you have to make sure that you don’t get carried away and get a
lens with a wider maximum aperture than you need.
Why?
Because
the wider the lens gets, the more it costs — and I’m not talking about
pocket change here. Since maximum aperture is directly related to
aperture, let’s talk about that one first.
4.First vs Third Party Lenses
When
it comes to first vs third party lenses for digital SLR cameras,
there’s usually a tradeoff: price vs. quality. Many of the third party
lenses are not as expensive as those made by camera manufacturers and
when it comes to lenses you do get what you pay for. However, many of
the third party lens companies have recently produced exceptional lenses
that aren’t matched by any similar first party companies.
This makes them a tempting alternative for those who don’t want to spend a week’s salary on a camera lens.
5.Digital SLR Lens Features
Before
you make a final decision about a lens, it helps to be familiar with
all of the extra digital SLR lens features. Think of it like this: when
you buy a new car, you can just get something that will let you drive
from point A to point B. That’s the basic approach…but you can also deck
out your new ride with a sunroof, power windows, heated seats, alloy
rims and a grab-bag of other enhancements. While these extra features
aren’t really essential, they certainly add to your enjoyment every time
you get behind the wheel.
These “extra” digital SLR lens features aren’t all that different.
