This is part two or our explanation of digital SLR cameras, if you missed the first part, you can click here to read it. We are going to look at some of the key features that gives identity to a digital SLR
over the digital cameras that we all know and use every day.
You attach a lens to suite your present need
Another feature of the DSLR is that the lens can be changed and the photographer can attach any to suite the need.
Ever seen those big time photographers holding up BIG cameras and continuously moving their fingers to adjust their protruding camera lenses. If you have then you've probably seen a digital SLR camera in action. Of course the photographer does not need to continuously adjust the lens as there is an optical system that allows the DSLR to maintain focus on a subject.
Using the right lens to shoot a scene can make all the difference to the quality of your picture. You need a different digital SLR lens for a different scene - this is where using these cameras can require a professional as they may know or a hobbyist whose dedication and passion can enable him or her to develop the skill to use the DSLRs. We discuss this in detail on the digital SLR camera lens section .
Large image sensors that produce high picture quality
An IMAge sensor is a device found inside a camera that is used t convert a visual image to an electronic signal. The typical image sensor is about 35mm, which is the same size as a camera film. Digital SLRs have large image sensors that produce high-quality photos. These come in various sizes with medium format being the largest ones. These largeness means better quality but also high price.
There are also full-frame sensors which essentially are the same size as the camera film i.e. 35mm. We will not go over the full list of sensors available out there but we hope you get the idea that the bigger the sensor the better the quality but also the more expensive the digital SLR camera is likely to be. In essence all of the sensors used in DSLRs are much larger than the sensors found in digital cameras.
In addition, the larger the size of the sensors the better the control of what is known as depth of field. This means a photographer can blur a part of an image to make another part more clearer. We discuss this in detail on the digital SLR camera sensors section .
Quick click and shoot - no lag time
An SLR has a near-zero lag time, and is ideal for action photography. You can take any moving image and capture the exact moment intended, which is often not possible with most digital cameras.
By now you must have a pretty good idea what a digital SLR camera is and you are probably starting to have an idea if you need one or better stick with the conventional digital camera.
