Choosing A DSLR Camera – Some Considerations

There are a wide range of alternatives and functions obtainable for DSLR (digital single lens reflex) cameras and it can be confusing if you are acquiring this type of camera for the very first time. This guide will help you determine which features are important to you and hopefully help you to decide on your best DSLR camera.


A major issue in your decision is, of course, the cost. DSLR cameras start off at about $ 400 and can be as significantly as $ 8000 for a top of the variety camera. A camera of between $ 400 to $ 1000 would most likely be a great select for a newcomer. Lenses tend to be pricey and can expense far more than the camera physique do make sure you take this into account when you make your price range.

Format Size

There are four format sizes at the moment for 35mm DSLR cameras.

Complete Frame

This format, with a sensor size of sensor size is 36mm x 24mm, is identified on most greater finish cameras and is the very same size as that employed in 35mm film cameras.


On a Canon camera this format has a 15mm x 22.5mm sensor and on a Nikon 15.6mm x 23.7mm. This format is employed by most DSLR cameras except some larger finish cameras and Olympus makes. Nikon call it a DX format.


This format is only identified in a couple of cameras such as the Canon EOS 1D MkIII and has a 18.7mm x 28.7mm sensor.

Four Thirds

This is a smaller sized format at 13.5mm x 18mm and is discovered on Olympus and Panasonic cameras. The aspect ratio is 3:4 in contrast to other cameras with an aspect ratio of 2:three.

All of the formats will give a good print out up to 11″ x 14″ which is the biggest most amateur photographers will usually require. Most cameras below about $ 1000 dollars use the 4 Thirds or APS-C format so the decision is usually dictated by the price tag rather than functionality.

Image Stabilization Systems

Systems for image stabilisation differ between makers. Some systems are mounted in the camera body other people on the lens itself. Nikon and Canon use a lens based technique and use gyros on the lens to sense movement and keep the optical groups stable. Gyros mounted on the camera body are employed by Sony, Panasonic and Olympus in a stabilisation program named a sensor shift. The sensor shifts to compensate for any movement. Though each systems carry out equally as effectively the lens mounted systems need to be included on every single lens which adds to the cost. In addition not all lenses have the technique incorporated especially prime lenses under 200mm.

Size and Weight

Less expensive cameras have a tendency to be smaller sized and lighter even though, as no DSLR camera is going to match into a pocket anyway, the size is not of primary essential.

Pixel Count

DSLR camera start off at about six mega pixels (MP) and can be as significantly as 22 MP for a higher finish camera. The pixel count will dictate the size that a print can be blown up to and you need to have to make a decision how big you would like your prints just before you make a decision on which model to get. 240 pixels per inch will give a really good good quality print so a 6 MP camera will be sufficient for a higher top quality eight” x ten” print.

If you need to have larger prints a ten MP camera will be capable of making a very good print at a size of 11″ x 14″. A leading of the variety camera with a pixel count of 22 MP will give superb 11″ x 14″ prints.

ISO Settings

ISO ranges between 100 and 1600 are discovered on most reduce finish cameras. Mid variety cameras may possibly have settings up to 6400 and a higher end camera can reach as higher as 25,500 and as low as 50. Most DSLR cameras will give pictures with low noise at ISO settings between one hundred and 800 but the noise dramatically increases above this. The noise at the greater levels can differ significantly in between models so, if attainable, try to see photos taken at greater setting with the cameras you are considering.


All digital photos will have some noise which will be much more noticeable at greater ISO settings. Noise comes from the electronics and sensor when the digital signal is created from the analog signal. All DSLR cameras have noise filtering systems but this operates less effectively above an ISO setting of about 800. Noise reduction softens the image so attempt to see photos taken in low light if you will be employing the greater range ISO settings.


Autofocus systems differ a excellent deal in between makers. All auto concentrate systems work well for static pictures but can differ a fantastic deal for moving subjects, particularly in low light. Check evaluations of specific cameras for information on how properly auto focus functions for the model you are considering.
