A wide range of options and functions available for digital SLR (digital single lens reflex) cameras and can be confusing if you purchase this type of camera for the first time. This guide will help you decide what features are important to you and I hope to help you choose the ideal digital SLR camera.
Price
An important factor in their decision is, of course, price. DSLR cameras start at about $ 400 and can be up to 8,000 dollars for a top range of the camera. A camera between $ 400 to $ 1000, would probably be a good choice for a newcomer. Lenses tend to be expensive and can cost more than the body of the camera, be sure not to take it into account when making its budget.
Format
There are four formats to the time of 35 mm for digital SLR cameras.
Full Frame
This format, with a sensor size of the sensor is 36mm x 24mm, is found in most higher end cameras and has the same size as the 35mm film.
APS-C
In this format a Canon camera has a sensor 15mm x 22.5 mm and a Nikon 15.6 millimeters x 23.7 millimeters. This format is used by digital SLR cameras with the exception of some higher end cameras and Olympus ago. Nikon DX format called.
APS-H
This format is only a few cameras like the Canon EOS 1D Mk III and has a sensor of 18.7 mm x 28.7 millimeters.
Four Thirds
This is a smaller format in 13.5 millimeters x 18 millimeters and is in Olympus and Panasonic. The aspect ratio is 3:4 unlike other cameras with an aspect ratio of 2:3.
All formats will give a good print to 11 "x 14", which is the largest amateur photographers usually need. Most of the cameras for less than $ 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 mounted on the camera body to others in the lens. Nikon and Canon uses a lens system and the use of gyroscopes, in order to detect the movement and to maintain stable optical groups. Gyros mounted on the camera body are used by Sony, Panasonic and Olympus in a stabilization system called a change of the sensor. The changes of the sensor to compensate for any movement. Though both systems work equally well as the positioning of the lenses must be included in each lens that increases the cost. Moreover, not all the objectives that the system includes objectives, particularly in the first 200 mm.
Size and weight
Less expensive cameras tend to be smaller and lighter, but as digital SLR not fit in your pocket in any case, the size is not of primary importance.
Pixel Count
Start digital SLR about 6 megapixel (MP) and can be as much as 22 MP camera for high-end. The number of pixels determines the size of a print can be expanded and will have to decide which format you want your opinion before deciding which model to buy. 240 pixels per inch will give a print of excellent quality as a 6 MP camera will be suitable for high-quality 8 "x 10" print.
If you need to print more than a 10 MP camera will be able to produce a good impression on a dimension of 11 "x 14". The top of the camera range with a pixel count of 22 MP to excellent 11 "x 14" prints.
ISO settings
100-1600 ISO range found in most lower-end cameras. Mid-range cameras may have a setting to 6400 and a high-end camera can be as high as 25,500 and a minimum of 50. Most digital SLR cameras that provide images with little noise at ISO settings between 100 and 800, but the noise increases significantly above this. The noise at higher levels can vary considerably between models, if possible, try to see the photos taken at the highest value with the cameras you're considering.
Noise
All digital images have some 'noise that will be more evident in higher ISO settings. The noise comes from the electronics and the sensor when the digital signal is generated by the analog signal. All digital SLR cameras equipped with filtering noise, but this does not work so well on an ISO setting of 800. Reducing noise softens the image to try to see the pictures taken in low light, if you use the higher range of ISO settings.
Cars
Autofocus systems vary greatly between manufacturers. All systems of auto focus works well for static images, but can vary considerably for moving subjects, especially in low light conditions. Reviews of cameras to monitor specific information on how the autofocus works well for the model you're considering.
