In my last post “Choosing a DSLR (Part-I)” I explained one of the 5 steps that I would recommend to choose a DSLR. In this post I’ll emphasize on the remaining steps.
2. Getting familiar with the important features.
In the previous step I only stated the feature that you will be looking in your new DSLR. Let me brief out the features along with some common specifications.
1.1. Image Stability- One of the most important features you will like to have in your DSLR. This feature is required in almost all the available scenarios and comes in two ways these days; one integrated with in the camera body and other in the lenses. When activated minor tremble to the camera will be eliminated resulting in sharper, crispier images even in the darker conditions. Some manufacturers term it as “Vibration Reduction” and some call it “Image Stabilization” but both means the same.
1.2. Sensor Size- Basically larger sensors capture even a finest detail of your subject. Digital cameras use an array of sensors containing millions of tiny pixels which constitute to your final image. Each pixel contains a bucket like structure called “photosites”. When you press the shutter release button the light rays coming from camera’s lens is poured in to these photosites and once your camera completes the exposure, these photosites are sealed. These photosites are then internally processed to apply true colors using filters.
Although understanding these sensors is a big chapter and might occupy two three posts of mine but I tried my best to brief out in a layman’s terms.//
A camera that has large sensor will try to grab more of these light particles and thus fill in more of those photosites resulting in attaining a great detail of the subject. Following are some common sensor sizes available:
