Digital Camera Lens
Select your Digital Camera Lens carefully!
There are many different options when it comes to selecting photographic equipment, but you will generally get what you pay for. The cheaper the equipment, the less versatile it will be, and the less professional your photographs will look. The two most important factors to consider are the resolution you will be able to achieve and the digital camera lens you get to work with. Cheaper models have what we call a fixed digital camera lens that may or may not give you the option of zooming in and out of the shot. The more expensive models, specifically the digital single lens reflex (SLR) camera, may be used with a variety of inter-changeable lenses. This means that you can start out with a standard digital camera lens, and then build up your equipment with various other lenses like a wide angle or telephoto, depending on your needs and budget.
Even though some companies, Sigma for example, make lenses that may be used with different makes and models, it is generally best to use lenses that are made by the same manufacturer that made the camera you decide to buy. You need to be clear about the fact that you can't use Nikon lenses with other types, like Canon, Panasonic or Olympus. This is because the different manufacturers design the mount required to fit their particular lenses.
If you buy a model that has a fixed lens that you cannot remove, you might be able to use an adaptor to make it more versatile. Some have a screw thread at the front of the integral camera lens, where the adapter can be screwed on. Other types of cheaper adapter lenses clip over the front of the barrel. Just be aware that you won't get the same optical quality from these lenses as you would if you were able to use the inter-changeable types. If you go for an adapter, if possible buy a matched sort that is meant for your particular model, and if you can, an adapter made by the same manufacturer.
Most models today have a built-in zoom that will allow you to get close to objects that are quite far away. So remember to take this into account when you consider or analyse your digital camera lens.
