The world of photography can sometimes be a complicated one. Jargon gets thrown around and sometimes it’s the user who suffers, for this reason today I’m going to write an article just for you explaining exactly what you need to look out for when purchasing a DSLR camera.
Megapixels are thrown at us every time the word photography comes up however you would be surprised to know that megapixels don’t always determine the quality of our final image. If you get a 10 megapixel camera or if you get a 16 megapixel camera then chances are that you probably won’t be able to tell the difference in quality at all. So if you’re looking at a camera you like but it only has 10 megapixels compared to the newest camera hat has 16 megapixels then don’t worry because this is just what the marketing department want you to do.
The more Megapixels you have then the bigger you can print the image out. Anything higher than 6 megapixels will allow you to print out everyday photos, while cameras with 21megapixels will allow you to print an image to cover the side of a bus.
Without getting too technical the ISO level of a camera allows you to capture an image with a quicker or slower shutter speed. Bumping up the ISO will mean that you will get a quicker shutter speed while lowering the ISO will have the opposite effect. There are many reasons why you would want to raise your shutter speed one of which is to avoid camera shake which will cause a blurry image. Raising the ISO however decreases the quality of an image and causes a grain like effect to appear in you images if certain conditions are present.
Most entry level cameras will perform at an iso range between 100-1600 where as some go up to iso 3200. To be fair to most of these entry level DSLR cameras they perform reasonably well at the higher ISO speeds.
Frames per second
Now this criteria may not be important to some, however as I tend to shoot fast action shots I consider it something to look at when purchasing a camera. Frames per second are the amount of shots you can take a second. Entry level cameras take roughly 3 frames a second while higher end DSLR cameras such as the canon 7D can take 8 frames a second.
The more frames your camera can capture at any one time is better, at least if you’re looking to photograph sporting events.
You will also want to take into consideration the cost of the camera and see if you can find it for cheaper or as part of a deal. Many camera manufactures will sell their items at a higher price, however if you look around you can often find deals with extra lenses included and other useful accessories.
