CAMERA LENS EXPLAINED There's a lot to know about lenses but its definitely worthwhile learning about. In a nutshell, the larger the diameter of the lens and the shorter it is lengthwise, the more flexible it will be allowing you to shoot in low light conditions. However that's not the whole story... there is also the issue of optical construction quality inside the lens but thankfully there is an easy way to tell if a lens is good or not just by looking at it.
Less than 21 mm = Extreme Wide Angle
eg. our mentioned 33mm - 105mm zoom lens will be able to cover everything from wide angle to medium telephoto photography.
The F stop rating is a measure of the lenses ability to capture light. The lower the numbers the better the optical quality of the lens and the greater their ability to capture an image in low light. In the example of F3.5 - F5.6, the 3.5 part (the lowest of the two numbers) is the rating of the lens at wide angle and the 5.6 is the rating at full zoom. Typically F3.5 at wide angle is only an average sort of lens where something like F2.0 is brilliantly fast and something like F1.4 is a super expensive pro grade lens.
