A camera between $ 400 to $ 1000 would be a good choice for a newcomer. Lenses are usually expensive and can cost more to make sure that the camera is taken into account the fact that if you make your budget.
Format Size
There are four formats in the moment of 35mm DSLR.

APS-C
On a Canon camera, this format has a 22 x 15mm. 5 millimeters and a sensor 15 Nikon 6mm x 23 7mm. This format is used by most DSLR cameras, with the exception of some upper and Olympus cameras. Give a Nikon DX format.
APS-H
This format is only a few cameras like the Canon EOS 1D Mk III, and found one on 18 7mm x 7mm-sensor 28.
Four Thirds
This is one dimension less than 13 5mm x 18 mm and is in the Olympus and Panasonic cameras. The aspect ratio is 3:4 in contrast to other cameras with an aspect ratio of 2:3.
All formats are better than prints up to 11 "x 14", who need the biggest, most amateur photographers will be as a rule. Most cameras below $ 1000 U.S. dollars using the Four Thirds or APS-C, so the choice is usually dictated by price rather than performance.
Image Stabilization Systems
Image stabilization systems vary between manufacturers. Some systems are elsewhere on the camera lens is mounted. Nikon and Canon are using a system based on slow and feel the roundabout on the lens, movement and keep the light clusters stable. Gyros mounted on the camera are used by Sony, Panasonic and Olympus in a stabilization system that is shifting, as the sensor. Strata sensor to compensate for any movement. Although both systems perform as well as the lens mounted systems must be included in each objective, which adds costs. Moreover, not all the objectives of the system have included predominantly first under 200mm lenses.
Size and weight
Cameras are generally cheaper than smaller and lighter, however, because DSLR fits into a pocket, however, is not the size of primary importance.
Number of pixels
DSLR cameras start at about 6 megapixel (MP) and can be as much as 22 MP camera for high-end. The number of pixels will dictate the size, the pressure can be blown up and you need to decide how big you want your prints before deciding which model to buy. 240 pixels per inch will give a good print quality, as a 6 MP camera is a high quality 8 "x 10" print is sufficient.

Mid range cameras can adjust the settings until 6400 and a high end camera can reach as high as 25,500 and the lowest 50 Most DSLR cameras are images with low noise at ISO settings from 100 to 800, but the noise increases dramatically on it. The noise at higher levels can also vary between models, if possible, try to imagine a greater acceptance with the cameras you are considering to see hit.
Noise
All digital images have some 'noise, which may be more evident at higher ISO settings. The noise comes from the electronics and sensors, if the digital signal generated by the analog signal. All DSLR cameras are equipped with systems for filtering noise, but works less well at ISO 800 setting noise softens the image around to try to see the pictures taken in low light conditions if they are more ISO settings.
Autofocus
Autofocus systems vary between manufacturers. All systems are suitable for autofocus static images, but can vary widely for moving subjects, especially in low light. Check reviews of cameras for information on how it works and AF for the model that you are considering.
