How to Choose a Digital Camera Lense
Executive Summary About Digital Camera Lenses by Collin L.
What should we look at when we are selecting our first lens to go with our camera to ensure a comprehensive beginners experience.
When deciding on a first lens, there are several factors you will want to consider:
Cost
There are excellent digital camera lenses available that will add from $100 to $300 to the price of your digital SLR camera if purchase at the same time.
Zoom Range
If this is your first and only lens, you will want a fairly long zoom range to provide the flexibility you will required as much as possible. Fortunately the two most popular kit lenses that come with most digital SLR camera have a 3X to 5X zoom ranges, extending from moderate wide-angle/normal out to medium telephoto.
Adequate Maximum Aperture
When you get your lens, you will want an f/stop of at least f/3.5 to f/4 for shooting under fairly low light conditions. The thing to watch for is the maximum aperture when the lens is zoomed to its telephoto end. For normal kit lens, you may ended up with an aperture of no better than an f/5.6 maximum.
Image Quality
Your starter lens should have good image quality, because that is the primary factors that made you upgrade to a digital SLR camera. Even the lowest priced kit lens includes extra-low dispersion glass and aspherical elements that minimize distortion and chromatic aberration. It should be sharp enough for most applications.
Size Matters
You will definitely not want to carry a camera that weights a tonne because of its lens. A goow walking around lens should be compact in size and light in weight.
Fast/Close Focusing
The lens that you selected should have a fast autofocus system. A kit lens with an ultrasonic motor/USM will be perfect for the job. Close focusing (to 12 inches or closer) will let you use your kit lens for some types of macro photography.
