There is only so much that a point-and-shoot camera can do for the average consumer. If a consumer wants to be able to break through those boundaries and obtain more value from their digital camera, then investing in a quality digital single-lens reflex (SLR) camera would be the best route to take. There are several different steps that need to be followed in order to find the very best deals on digital SLR cameras.
Most digital SLR cameras utilize image sensors that are much smaller than the traditional 35mm film frames but larger than the sensors that are usually found within point-and-shoot cameras.
· The basic APS-C sensor provides a "cropping factor" of 1.5x (which means that an upgraded 18-55mm kit lens is able to cover an equivalent of 27-82.5mm.
There are several key benefits that can be experienced simply by purchasing a larger sensor when shopping for a DSLR camera. For example, consumers are able to:
- control the field depth within images
· isolate their subject in order to create a blurred background effect
- minimize excessive image noise
· gradually change the brightness or color for enhanced, natural images
If a consumer is interested in purchasing a full-frame DSLR, he or she will need to focus on upgrading their lenses as well in order to be compatible with their sensors. For example, Canon has an expanding line of EF-S lens that can easily be referred to the APS-C lens line.
Focus on the Most Comfortable Model
One of the most important factors that need to be considered when shopping for a digital SLR camera is the level of comfort experienced by the consumer with those specific models. Keep in mind that different models may look and feel completely differently than others. The size and build might be very similar, but several key differences that may exist include:
- the styling and texture of the handgrip
- the strategic positioning of controls
- other popular ergonomic features
Whenever a consumer is shopping for a digital SLR camera, they need to focus on finding a model that is going to be the most comfortable for them to use on a regular basis. If the camera is not very comfortable to use, the odds are that it will not be used as frequently as it actually could be in the long run.
Finding a High-Quality Viewfinder
In addition to finding quality, comfort and an efficient image sensor, another key point that needs to be considered when shopping for a digital SLR camera is the viewfinder that comes along with this particular mode. The optical viewfinder on a DSLR camera is designed to show the photographer the exact image that is being captured by the lens. An internal mirror is able to guide the light from the lens directly to the actual viewfinder. There are two different types of viewfinders that are currently available, including the:
· pentamirror (usually found on basic, entry-level cameras)
o redirects image directly to the eye through the use of three key mirrors
o image that is being captured is flipped in order to appear correctly
o usually found in entry-level DSLR cameras
· pentaprism (solid glass prism; performs same duties as pentamirror)
o widely known for being brighter and heavier than pentamirror
o increased brightness makes framing images much easier
o it is also much easier to check whether or not a picture is in focus
o usually appear in mid-range DSLR cameras
Pay close attention to the coverage numbers and magnification levels for pentaprism viewfinders, because these figures will provide you with a general idea of the approximate size of the actual finder as well as how much of the exact image is visible. Regardless of the scenario, the goal should be to always have a high number.
- electronic viewfinder (redirects light towards autofocus sensor)
o commonly used as third viewfinder selection
o semitransparent mirror directs light towards autofocus sensor instead of eyes
o consumers that are not ready for an optical finder usually choose this option
The Benefits of Autofocus Speed and Continuous Shooting
In addition to the physical features and components of a digital SLR camera, consumers also have to pay close attention to the actual capabilities of each specific model as well. Two of the most popular characteristics that are checked for by consumers as they shop for these cameras are the autofocus speed and continuous shooting.
· Continuous Shooting: measured by calculating the number of frames that is captured per second. A good quality DSLR camera will have a continuous shooting speed of at least three frames per second. Top-quality DSLR cameras will have at least a shooting speed of five frames per second, such as the models that are used by professional nature and sports photographers.
· Autofocus speed needs to be able to maintain the same pace as the frame rate. The lower the number of actual autofocus points, the slower the overall performance of that particular model.
Shopping for Accessories and Lenses
Keep in mind that most digital single-lens reflex (SLR) cameras do not come with any lenses; they are usually sold with just thecamera bodies and several standard accessories included. Therefore, it is important to at least have a basic understanding of some of the standard lenses that are available, which you will need to at least consider when shopping for DSLR cameras:
- Telezoom : Many consumers prefer to purchase a telezoom lens that can complement the basic 18-55mm lens that has a matching zoom of at least 55mm to capture tight shots from far away.
- Normal-angle Prime Lens : The field of view from a normal-angle prime lens is very close to the field of view for the naked eye. The quick aperture rate allows photographers to be able to shoot high quality pictures in low areas of light. Isolating a subject becomes even easier to do with this type of lens so that the photographer can artistically blur the background.
- External Flash Units : Quite a few DSLR models come as standard with built-in flashes, but most photographers prefer to invest in external flash units for enhanced performance and power. External flash units are designed to emit a substantial amount of more light and can even be repositioned in order to use the light that is being reflected to properly illuminate the subject of the photograph.
How to Buy a DSLR on eBay
There are quite a few different DSLR camera models that can easily be found on eBay. To access the complete listing, go to the eBay homepage and use the Search field to search for relevant keywords and phrases such as "DSLR cameras" or " DSLRs."
For specific brands and models, the Search field can also be used to identify the preferences of the consumer. For example, he or she could search for "Nikon DSLR cameras," "Canon EOS DSLRs" or specific models like the " Nikon D800 DSLR." Quite a few camera accessories are also available on eBay for consumers that are interested in upgrading the models that they may have already purchased.
Find "free shipping" offers to maximize savings and avoid making purchases from sellers that have an extensive history of negative feedback and poor ratings from past customers. Take the time to have all questions answered and concerns addressed before finalizing any purchase.
Point-and-shoot cameras used to dominate the world of photography in the past. It is clear that advancing technology and mobile devices has drastically changed those days, making DSLR cameras and accessories much more popular in today's market. Whether a consumer is interested in purchasing Nikon, Canon, Sony or any other brand, it is imperative that he or she understand the basic principles of wisely shopping for these cameras whenever the need to do so arises.
