Choosing a digital SLR camera – Some thoughts

There is a wide range of options and functions available for DSLR (SLR optical digital) cameras and it can be confusing if you buy this type of camera for the first time. This guide will help you decide what features are important to you and hope to help you choose the ideal digital SLR camera.

Price

An important in their decision is, of course, price. Digital SLR cameras starting at $ 400 and may be less than $ 8,000 for a high end camera. A camera between $ 400 to $ 1,000 may be a good choice for newcomers. The lenses are usually expensive and may cost more expensive than the body of the unit make sure you take into account in its budget.

Format size

There are four sizes in the time format 35 mm SLR.

Full Frame

This format, with a height sensor size 36mm x 24mm sensor, is in the top of most digital range and the same size as 35mm.

APS-C

In this format, a Canon camera with a sensor of 15 mm x 22.5 mm and 15.6 23.7 mm x Nikon. This format is used by most digital SLR cameras, except for some high-end cameras and Olympus. Call Nikon DX format.

APS-H

This format is only a few cameras like the Canon EOS 1D MkIII sensor and has a 18.7 mm x 28.7 mm.

Four Thirds

This a smaller size of 13.5 mm x 18 mm camera and Olympus and Panasonic. The aspect ratio is 3:04 in contrast to other devices with a ratio 2:3 aspect.

All formats will give a good impression up to 11 "x 14", which is the largest amateur photographers most commonly need. Most cameras below $ 1,000 U.S. dollars at the Four Thirds or APS-C while the format of choice is usually dictated by the price rather than performance.

Image Stabilization Systems

The image stabilization systems vary by manufacturer. Some systems are mounted on the camera body to others in the target itself. Nikon and Canon uses a lens system based on using gyroscopes to detect motion and maintain the stability of optical assemblies. Gyroscopes mounted on the housing of the device are used by Sony, Panasonic Olympus and stabilization system calls for a change of sensor. Sensor to compensate for changes in motion. Although the two systems work as well as systems Lens mounted shall be included in all objectives in addition to costs. In addition, all the goals that the system includes the pump in particular under lens 200mm.

Size and weight

Thirteen cameras tend to be smaller and lighter, but like any digital SLR camera does fits in a pocket of all, however, size is not paramount.

Number of pixels

DSLR will start at 6 mega pixels (MP) and can be as much as 22 MP cameras upscale. The number of pixels that determine the size of a print can be expanded and will decide the size you their views before deciding what model to buy. 240 pixels per inch gives a very good print quality as a camera 6 MP will be suitable for a high quality 8 "X Letter 10.

If you need more tests for a 10 MP camera will be able produce a good print size 11 "x 14". A high-end device with a number of pixels 22 MP gives an excellent 11 "x 14".

ISO Settings

ISO 100 and 1600 are in most low-end devices. Camera settings midrange can be up 6400 and a high end camera can as high as 25,500 and as low as 50. Most digital SLR cameras produce images with little noise settings ISO 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 images taken with the greatest value with the cameras you are considering.

Noise

All digital images have a bit of noise, which is more sensitive to higher ISO settings. Noise comes from the electronics and the sensor when the digital signal is produced from the analog signal. All digital SLR cameras have noise filtering systems, but this does not work so well on a 800 ISO setting. Reducing noise softens the image to try to see the pictures taken in low light, if you use the high-end configuration of the ISO.

Auto Focus

Autofocus systems vary considerably between manufacturers. All AF systems work well for static images, but can vary considerably for subjects moving, especially in low light. Check Camera specific information on how the autofocus model that interests you.
