The number of advantages to buying a digital camera to replace your old one are too big to ignore. For example, you can take as many photos as you want, no longer being limited by the film you have on you.
In order to select the right camera you might want to analyze products from Canon, Nikon, Kodak, Sony and Olympus. Why these manufacturers? It's easy: Canon and Sony offer the highest technology available on the market, Kodak cameras are well known for their user-friendly interfaces and great balance and last but not least, Olympus offers great features like waterproofing that might come in handy every once in a while.
Choosing a first digital camera means that you should go with something that isn't hard to use. At the same time, the camera should have a few extra options, so you can experiment with them as you learn photography. Since it also has auto mode, you can learn photography techniques or take quick photos, depending on what you want.
The best criteria to judge a digital camera on and differentiate between different models is their resolution. Having a large resolution means that the photos will be larger, sharper and with less blur. You can find out how good the resolution is by looking at how many mega-pixels the camera has. Look for cameras with more mega-pixels. Bigger is better in this situation, but it also means a bigger price. The camera you want might be expensive now, but with the technology that advances so quickly, the price goes down every year.
The second thing you should look for is the optical zoom. It's not the same thing as digital zoom. The digital zoom will enhance the image from the software, while cutting the photo's edges. The result is a low quality zoom, with a fuzzy photo. The optical zoom however is done from the hardware level, so it's much better at delivering quality photos.
The third thing you should look for is the size of the digital camera. If you want to do professional photography you will have to go for the bulkier, larger models, not to mention more expensive. They're better because the large number of features, the possibility to take great zoom shots and the lenses that can be changed. The price is going down, but they're still expensive. If you're not going pro, you might consider buying something smaller that is easier to carry around and is easier to use.
If you go with a compact digital camera that is high end, it will still cost quite a bit, but it also comes with different essentials and accessories. The advantage with small digital cameras is that they can be carried around much easier.
If you're planning to carry around the camera everywhere you go it would be best to buy a compact one but if you're trying to build yourself a photographer career then you must buy a SLR. If you want to buy the camera for taking pictures during a football game then the controllability feature is what matter the most and not the actual size of the device. On the other hand, size is very important when you go on a trip and you want to capture ever single beautiful location you'll visit.
Digital Camera Lens Types:
Fold optics lenses - Fold optics lenses are the ones that fold sideways to the camera's body. This kind of lens is very sleek and compact. Lenses of this type are very much protected by its built-in cover. Although these lenses are suitable for those who like compact devices, these models don't support lens converters. Based on different reviews, these lenses produces lower optical quality despite its higher costs compared to that of external lens designs.
Fixed zoom lenses - Fixed zoom lenses are not retractable even if the camera is turned off. However, this kind of "flaw" has its own use since these lenses can magnify objects at an average of 18 times. Attaching lens converters to perform different kind of shooting would not be a problem with these lenses. Fixed zoom lenses are commended for business users and serious amateurs in photography.
Fixed focal length lenses - Snap-shooters and budget buyers should take advantage of this kind of lenses. It doesn't have an optical zoom to magnify objects. It is also very affordable. Cameras with fixed focal length lenses always have easy and quick camera operations. Although these lens provide the lowest quality available in the market, they are very good for shooting wide angle views such as landscapes and group shots.
Retractable zoom lenses - Although cameras with these lenses do not support lens converters, they are still very suitable for budget buyers and snap-shooters. These lenses are always paired with sleek and compact designs to give it a very light look. This type of lenses, however, is not suitable for people who like to manually set controls since its switches are always limited.
Interchangeable lenses - Only digital SLRS offer you the chance to change lenses. Interchangeable lenses are recommendable to serious amateurs who want to have flexibility in handling subjects and views. Cameras with interchangeable lenses will enable you to save money since you won't have to buy new cameras for different kinds of photography.
Megapixels and Resolution - 3-megapixels is a good compromise between quality of picture and camera price. You can print good quality 4x6 images,quite good 5x7s and if a good camera possibly larger prints.
4-5 megapixels and you can begin to think about enlargements of your photos.
6+ megapixels gives great quality pictures and quite big enlargements.
However, there is a trade-off. More megapixels means higher prices, more memory usage and the camera takes longer to process shots.
Most digital cameras come with quite a low amount of memory and it is always better to include the cost of a memory card while purchasing a camera.
The digital camera memory card is where you store your images until you transfer them to your computer. This is not to be confused with the internal memory of the camera. The size of the memory card will determine how many images it will hold before you need to clear the memory and take more pictures.
The digital camera memory card will hold different amounts of images. For instance, the six megapixel camera with a one gigabyte memory card will hold approximately three hundred images before you have to transfer pictures. The higher the megapixels the less the memory card will hold. Beside the different companies that make the memory card there are six different types. There is the multimedia, SmartMedia, xD memory cards, secure Digital, MemoryStick and CompactFlash memory cards to choose from when you are looking for storage.
Memory Stick - The memory stick is an invention by Sony. As a result, these cards can mostly be used only on Sony devices. Hence, if you have a Sony digital camera, a Toshiba laptop; then it is most likely that you will not be able to use your memory stick on both equipments.
Secure Digital & Multimedia Cards - Commonly known as the SD card, these cards are one of the smallest memory cards which are available today. These cards can be used in different types of equipment, i.e. digital cameras, phones, MP3 players and video cameras as well. However, the maximum memory capacity is only 512 MB. The difference between the SD card and the multimedia card is that, as the name suggests, the SD card comes with an additional write-protect switch for data security.
Compact Flash Memory Card - Compact Flash is a relatively cheap memory card. It is available in most shops and is compatible with a large number of digital cameras. It is very popular and is commonly used by camera lovers. These cards come with an in-built controller which results in high transfer speeds. However, in order to use this facility, you normally need to be using a digital SLR.
Card Reader - Once you have purchased a memory card for yourself, you will also need a card reader in order to transfer your pictures onto your laptop or PC. The advantage of a card reader is that it can be directly attached to your computer through the USB port. Then you simply need to slot in the memory card into the reader, and you can transfer files easily. The card reader does not require any additional cables and neither does it use up the battery of your digital camera.
When traveling, X-Rays have never been shown to corrupt the data on, or damage, a digital camera memory card.
