What Kind of Camera?

What Kind of Camera?



Once you know what is important to you as a photographer,
it's time to start looking at the choices. Although there are many cameras,
they fall into three main categories.
Compact Digital Cameras (Consumer)
Easy to use, Point-and-shoot automatic cameras. These are the everyday snappies that most people own. Today almost all consumer cameras are digital, although you can still find some that shoot film.
Cheapest price range
Average price of a few hundred USD.
Simple and Very Compact
Small form-factors you can take anywhere
Automatic
good for point-and-shoot photography
Simplified Features 
most consumer cameras do not allow you to directly control exposure settings. Look to the specialized shooting modes exposure control


Prosumer Digital Cameras
Although they sometimes look similar to consumer cameras, prosumer (professional-consumer) equipment is packed full of features that serious photographers will love. Prosumer cameras usually have better lenses, higher detail, and much more control over exposure than their cheaper consumer cousins.
Medium to high price range
From $500 to over $1000 USD
Compact
It's amazing how much technology is in a prosumer camera. The fact that the camera is totally self-contained (lens, flash, etc) is a big selling point.
High Quality/ResolutionBoth the lenses and the digital CCD offer sharp images with great quality. Newer cameras can easily shoot for print publication.
Feature Packed
If anything, there are too many features crammed into the average prosumer camera. For the enthusiast photographer, this kind of camera is deal because it allows much room to grow.
Full Control
Above all, the prosumer camera gives the digital photographer complete control over the picture taking process.

Digital SLR Cameras
The Single Lens Reflex (SLR) design is often associated with professional photography. These cameras look and feel exactly like their non-digital cousins, and they even take the same lenses. For buyers considering a prosumer camera, a digital SLR is worth considering.
Medium to high price range
Most digital SLR's are over USD $1000, but recently there have been some *very* good models released for much less than that.
looks like a camera - feels like a camera - acts like a camera
These cameras look much more like the classic SLR. They are big compared to prosumer models, especially if the size of the lens is taken into consideration.
Standard Mount Lenses
Most digital SLR 's have standard lens mounts so normal lenses can be used. If you have a old Nikon or Canon lens collection. this is good news! The quality of SLR lenses are far better than most consumer or even prosumer cameras.
The Single Lens Reflex Advantage 
SLR means "single lens reflex", and these cameras allow you to see exactly what the camera sees when looking through the viewfinder. Most compact cameras have a barely useful eyepiece that isn't even remotely accurate for composition. This is changing with newer prosumer digital cameras which offer electronic viewfinders.
Highest Quality and Detail
Digital SLR's have drastically better quality than consumer or prosumer cameras. The size of the digital film element (the CCD) is much larger with these cameras, virtually noise-free with superb detail and quality.
Standard SLR Features
Digital SLR's are for the enthusiast or professional photographer, and tend to have more businesslike features without some of the extras found in the prosumer models. Compare camera specs for more info.
