So you've decided to buy a digital camera but you seem to be more confused as to what to buy. There are a lot of people telling you what matters most in a digital camera. Buy this... Buy that... Choose this and choose that... You might be going crazy with all of this so-called "advices." So let's try to narrow things down. What exactly makes a good digital camera? Is it resolution? Zoom? Maybe some other technical stuff? I will make it easier for you. I will list the things that make a digital camera worth your time (or not!). Some of these things may be a little too technical so I will try to make it less complicated for you simple folk out there. For this article, I will tackle resolution, lens and power supply. Take note that there are more things to consider but these are the main ones that you need to look for.
Resolution
Resolution can easily be understood as "image detailing". You see, pictures are made of pixels. The more pixels, the more detailed a picture becomes. But wait, albeit common belief more pixels does not equate to better photo quality. If you get a camera with very high resolution, you might get frustrated with slower shooting. If you choose a camera with very poor resolution, your pictures might come up as crap. So if you think that a 14-megapixel camera is light years away from a 12-megapixel camera, think again. They might even give the same quality of images under certain conditions.
Lens
In the digital camera world, there are a number of different kinds of lenses. Some have aesthetic purposes but most of them offer some form of technical advantage over the other. They can be broken down into 4 different kinds of lenses as mentioned below.
- Folded optic lenses- Usually present in ultra compact cameras, this kind of lens folds sideways maintaining the slim design of the camera.
- Fixed focal-length lenses - These lenses have no optical zooming capabilities at all. This has the lowest optical quality of the 4 types of lenses.
- Retractable zoom lenses -Currently the most common type of lens in the digital camera market. These lenses retract inside the body of the camera when not in use. The retraction/extension makes start-up and power-down times longer. Also, the design limits manual-focus through switches and/or buttons.
- Fixed zoom lenses -These lenses are fixed to the body and do not retract inside when the camera is powered off. Magnifications using these kinds of lenses can go to as high as 26x. Advanced controls allow the user to create adjustments if needed. The only thing about fixed zoom lenses is that it tends to make the cameras bulkier and operation of the camera may be more complicated.
Batterytypes
For power supply, it's always best if your camera can use interchangeable power supply simply because there may be times when it will be impractical to use one type of power supply. For everyday use, you can opt for rechargeable batteries because they tend to become cheaper on the long run. But if you are in the woods for a long time, it would be better to bring a pack of disposable batteries rather than bring a rechargeable battery.
