For many photography enthusiasts, owning a digital SLR camera is an important first step. There are a number of different makes and models of SLR cameras out there - they come in a variety of speeds and megapixels and all have a range of camera accessories. Learn about how DSLR cameras work and what to look for before you make your purchase.
What is a DSLR camera?
SLR stands for single lens reflex since you are looking at the actual image through the single lens. The image passes through the camera lens to a mirror that then reflects the light upward to a pentaprism or pentamirror before being reflected again through the viewfinder, where you can see what's actually in the frame. When the shutter button is pressed, the first mirror flips up so that the light passes through the shutter, thereby capturing the image.
SLR cameras allow for more accurate composition and colour balance since what you see through the viewfinder will be what you get in the final picture. Traditional SLR cameras used film but today's digital SLR cameras allow for digital capture so that you can review your images instantly.
How to choose a DSLR camera that's right for you
There are plenty of variations between the different types, makes and models of DSLR cameras. Choosing the best DSLR camera for your needs depends on how you intend to use the machine - and the amount you're willing to spend. Here are some points to keep in mind:
Cost - Your budget will determine the type of SLR camera you purchase. Remember that in addition to buying the camera body, it'll be worthwhile to invest in a couple of camera lenses as well. A good telephoto zoom lens, for example, is great for getting up close to your subject matter, while a wide angle lens increases the angle of your view so you can get more in the shot. You might also look into buying camera accessories, including filters, a camera bag or even an extra battery to make the most of your investment.
Megapixels - most of today's DSLR cameras start at about 8 MP and can go up to 24 MP or more. Having more megapixels means you get better resolution, which is great for large prints or for enlarging smaller parts of your image. Keep in mind that having more megapixels isn't the only way to get quality pictures. For example, in low lighting, too high a megapixel count could mean your photos end up with a bit of "noise" as your camera sensor might not capture the correct colour tone for every pixel, creating a bit of speckling in the image. Meanwhile, professionals may want a high megapixel count for large prints, such as billboards, or if they are significantly enlarging a small area of the final image. When deciding on how many megapixels you'll need, think about what you'll be using the photos for and whether you're looking for images to publish online, make personal prints or sell in a professional publication.
Speed - DSLR cameras are much quicker than the typical digital camera. You'll notice reduced shutter lag (the delay between pushing the button and actually capturing the image) with your DSLR. If you'll be shooting lots of action shots then you'll likely want a faster model.
Choosing the right digital SLR camera means doing your homework and finding out more information about the different options that are available, so you can be sure you'll get the results you want. Ask friends and families or look for an online forum and gain some valuable insights and tips from the experts.
