As the quality of point-and-shoot cameras continues to improve, so does the higher-end SLR (Single Lens Reflex) camera models on the market. Although photojournalists prefer the speed and durability of a $4,000 Canon or Nikon, several camera companies produce quality SLRs under $1,000 for amateurs. Here are some guidelines if you are considering one of these cameras.

WHY UPGRADE FROM A POINT-AND-SHOOT?

1. Making big color prints? Although point-and-shoot cameras match SLRs in image resolution (megapixels), there’s no question a SLR delivers better image quality. The secret is a larger sensor that captures and reads light. The most noticeable difference in image quality can be seen in low-light situations. At ISO settings greater than 200, the SLR has far less noise (grain) and a greater range of mid-tones.

2. Trying to get that deceive moment? Point-and-shoot cameras have an annoying lag time of 1-2 seconds between pressing the shutter button and exposure of the image. SLR cameras not only focus and shoot instantly, the technology helps avoid back focusing when the camera focuses on the background, not the subject.

3. Need more variety in lens choices? Although some point-and-shoot cameras have great zooms, SLR cameras have interchangeable lenses opening up a new world of photography.

DO YOU REALLY NEED TO UPGRADE? MAYBE NOT.

1. Do you shoot on the run? SLR cameras are much larger. There’s no putting one in a purse or pocket.

2. Like the movie mode on your camera? Forget about it on an SLR. It’s made for the more serious still photographer.

3. Only need 4x6-inch prints? Point-and-shoot cameras will fill your needs and then some.

4. Price a key consideration? You can get a quality point-and-shoot for under $300.
