A Zoom Len Is Very Versatile

By Ken Dragki

It is also a good idea to visit a store that specializes in cameras and lenses that go with them. Talk to the salespeople there, and get all of your questions answers. Find out about pricing too. Usually the higher prices are the more professional cameras.

When there is a shorter focal length, the field of view becomes wider, providing more scenes for your camera to capture. When you increase the focal length, the actual field of view becomes narrower.Slower shutter speed can result to blurry photos when cameras are handheld. Image stabilization counteracts the shaking, allowing one to shoot certain handheld shots amidst low lighting conditions.

Prime lenses are fixed focal length lenses like a 50mm 1.4f lens. To zoom with these types of lenses you need to use your feet and to get closer or farther away from the subject. Traditionally prime lenses are sharper and faster then zoom lenses. If you are on a budget you can pick up some amazing used older prime lenses off eBay or your local camera store.

Macro Lenses are your detail brushes as they enable you to get up close and personal with your subject. These types of lenses are used for extreme close ups on small objects like daisies, pennies, and food but not limited to these types of subjects. Examples of macro lenses are 50mm and 100mm macros. These lenses are also great for selective focus types of photos.

Lenses with long focal lengths 100mm and higher are called telephoto lenses. A long focal length seems to bring the subject closer to you and increases the subject's size in the frame. Telephoto lenses also give your subjects a graphic look and flatten out your subject. These lenses are my short stroke brushes.

These types of lenses are very expensive but so get what you pay for. When shopping for a zoom lenses check out the f-stop range rating. An example is a 24mm to 300mm f3.5-f5.6 lenses meaning the lowest f-stop you can shoot is at the 24mm range of the lenses and when you zoom to 200mm the lowest you can go is f5.6.
