My brother has been shopping for a digital camera for a while and still hasn't bought one yet. I asked him what type of digital camera he's looking for. "Well...a quality one" he replied. Well, I guess he doesn't really know what exactly he's looking for. So, I thought this would be a good topic to talk about - how to buy a digital camera based on your own needs.
Everyone has different needs when purchasing a digital camera. You have to prioritize them before you start looking. Here's how I prioritize my own needs:
1. Budget
This is the most important step because what you want is to find the best one within a specific price range. It's always easier to compare cameras once you set the budget. You probably wouldn't get a professional digital SLR cameras just because they're better than the point-and-shoot ones, would you? Once you determine how much you are willing to spend on a camera, you'll have a basic idea of what type of cameras are affordable to you on the market.
2. Zoom
Zoom is a pivotal function in a camera, and it can make a huge difference in your photo shoot. Most digital cameras these days come with 3x optical zoom, which is equivalent to 35-105mm range. It allows you to shoot decent photos within a reasonable range. But I prefer ultra zoom, at least 10x optical equivalent to 38-380mm. With 38-380mm range, you wouldn't have to worry about getting the front seat at your favorite concerts or your kids graduation. A couple of good ones with ultra zoom on the market are
Olympus SP-510 Ultra Zoom with 10x optical zoom, and
Canon PowerShot S3 IS
with 12x optical zoom.
3. Image Resolution
Image resolution is defined by the number of pixels of the image. The more pixels, the higher resolution and the bigger photos can be developed. Most digital cameras come with 6 mega pixels or above. You should invest in a digital camera with higher image resolution if you want to blow up some of your amazing photos.
4. LCD and Body
Most point-and-shoot cameras are compact and small in body, and I find them hard to handle. I prefer to use the ones with a heavier body and a bigger LCD, which provide you with better grip and larger viewing area. You also shoot better images with heavier body since your hands wouldn't shake easily.
These are the basic needs I look at and how I prioritize them. I'm leaving the technical talks to the experts. It's always a good idea to read consumer product reviews, but product technical reviews done by an independent third party is more helpful. It helps you determine a few brands and models before talking to the sales person. It saves you time and energy in the whole buying process. The one I regularly reference is Imaging Resource, who provide complete full reviews on all models by all manufacturers.
