New digital camera: Things to see when you purchase digital cameras

Many buy a new camera based on just a few parameters like purchase price and megapixels. This is unfortunate as there is much more to a new digital camera buying decision. This article will describe a holistic approach to that decision.

In the early days of the digital camera era buying a new camera was relatively an easy decision. Digital cameras did not have many options and checking simple things like price and the number of megapixels was enough. Since then however digital cameras have evolved and became more sophisticated. They have many new features and options. They can work with different accessories and use different technologies. Today when making a decision on a new digital camera a holistic approach that takes the different features and options into account is more suitable.

So what does it take to make a decision on a brand new digital camera? Following is a breakdown of what to check for when buying one. This list is not complete and you should use it as a guide to understanding the complexity of choosing a digital camera.

Cost: Do not confuse cost with purchase price. Purchase price is what you pay to buy the camera. Cost is the total money you need to spend including the purchase price in order to effectively use the camera. In most cases you will spend additional money on accessories and other additional products such as lenses, batteries, carrying cases and more. Failing to budget for those extra expenses can result in buying a camera just to find out it can not be effectively used without spending more.

User knowledge: It is important to buy a digital camera that is appropriate for its user’s photography level. If you are technology and photography savvy you can consider higher end cameras that allow more flexibility and manual options but are harder to use. Digital SLR cameras fall into that category. If you are not into photography or technology you might want to choose a camera that is easier to use such as a digital point a shoot one.

Expected usage: The digital camera you choose should be appropriate for its intended use. For example if you travel a lot for long periods of time you want to pay attention to features such as camera weight, size, battery life and memory storage. On the other hand if you hardly travel at all these features are less important.

Basic features: There are some basic features that are common to most if not all digital cameras. These features are:
Megapixels: you can not avoid the number of megapixels question. Is more megapixels better? It really depends. More megapixels is important if you are going to print photos and enlargements or if you are going to zoom in and crop photos. However if you plan to view the photos on your computer screen and occasionally print 4X6 copies then 2 or 3 megapixels is more than enough. Buying a digital camera with more megapixels is not a drawback but you should make sure that you could not have used the extra money spent on megapixels for other features that are more useful to you.

Batteries: Digital cameras use two kind of batteries disposable or rechargeable. Disposable batteries are easy to buy, carry and replace. They are available in any store and are very convenient when traveling. Disposable batteries however are more costly to use as you need to keep buying new batteries. Rechargeable batteries require only one purchase. However if they are empty during a photo shooting session or somewhere away from home or a power supply you can not just buy another battery. Take into account the cost of extra batteries based on the expected digital camera usage.

Zoom: There are two types of zoom – optical and digital. Optical zoom works by physically moving the camera’s lenses and changing the focal length. Digital zoom works by applying built-in software in the camera to define a portion of interest in the photo. Once chosen the software crops the rest of the photo and enlarges the area you chose. For quality and other reasons optical zoom is superior to digital zoom. From a practical point of view digital zoom should not be considered zoom at all. When you compare different digital cameras zoom figures always compare their optical zoom capabilities. You should ignore the digital zoom figures.

Accessories: Digital cameras can use a large number of accessories. You should be aware of what accessories are supported by your camera and which accessories you deem important to you. These should be taken into account in your buying decision. Some of the common accessories to consider:
Memory cards: Digital cameras store photos as files on a memory device usually a removable memory card. Most digital cameras are sold with a very small memory card. This lowers their purchase price. Such a small memory card can hold a small number of photos and is not practical. When buying a digital camera always check how much memory is included. Then assess how much memory you will need and check the prices of memory cards appropriate for you. Add this cost to the total cost of buying the new digital camera.

PC connectivity: Digital cameras connect to computers in order to download photos. The most common methods of connectivity are USB and plugging the camera’s memory card directly to the PC. Make sure that your camera includes the USB cable needed to connect to the PC. If you prefer connecting the removable memory directly to your PC budget an adaptor that can bridge between the memory card and the slots available in your PC.

Lenses: High-end digital cameras such as digital SLR often require additional lenses. When reviewing your camera check what lenses are included with the camera. If you need more lenses shop around for ones that fit your camera and budget their price. Lenses can be very expensive and can cost more than the camera itself. For example when buying an SLR camera for outdoor photography that requires zoom lenses make sure you budget such lenses that fit the camera you plan to buy.

External Flash: Most likely that you will not need to buy an external flash unit. If do need an external flash in addition to your camera’s built-in one make sure that you shop for one that can work with the camera and budget its cost before purchasing the camera. External flash units prices can vary and can be a costly addition.

Here you will get all latest information about latest digital cameras


Digital cameras come in a variety of different shapes and sizes. Different brands of digital cameras also offer users an array of features designed to make each and every shot fantastic. Despite the numerous features offered by digital cameras, manufacturers still manage to create products that are simple enough for a child to use.

Day by day digital cameras are becoming a well-known fixture in most homes across the globe. In fact, most of the people around the world own one and use it on a regular basis. Digital cameras have also been incorporated into a variety of technical gadgets that have been integrated into the lifestyle of people everywhere.

PDA devices as well as cellular phones are just some of the technological devices that have a digital camera feature. Despite being an add-on feature, the digital camera device installed in these gadgets fair relatively well compared to detached models.

As a matter of fact the memory used for digital cameras, detached models or otherwise, can easily be upgraded using memory cards. The added memory will certainly come in handy because most digital cameras can also be used to take video clips.

There are numerous brands of digital cameras available on the market today. Mainstream electronic brands like Nikon, Kodak, Canon and Olympus are just some of the manufacturers of conventional 35mm cameras who have jumped on the bandwagon to create their own lines of digital cameras. Other famous brands that manufacture digital cameras include Panasonic, Casio and Sony.

Basic Features of Digital Cameras to Consider

Regardless of brand names, digital cameras have the same basic features that any consumer should know and consider before buying one. Even though digital cameras are generally a point and shoot device, certain features can often single out a particular brand or model. A good example of this is the term megapixel, which became known when digital cameras were introduced in the market.

Megapixels, which means millions of pixels, measure the quality and size of a digital camera. Pixels refer to the dots that make up a picture. Therefore a digital camera that has about a 5-megapixel resolution will produce better quality pictures compared to a 3-megapixel digital camera.

Moreover, photos taken with a digital camera that offers greater megapixels can be enlarged safely without sacrificing the quality of the picture. Average digital cameras with less than 3 megapixels often forfeit the clarity of the picture once it is enlarged. Unfortunately, there is a downside to using a digital camera with greater megapixels as they consume more of the camera’s memory.

The zoom function of a digital camera is another feature that most consumers should consider. There are generally two types of zoom features for many of the digital cameras on the market today. The optical zoom feature is common in devices without permanent lenses. The user can simply zoom and focus on the subject to be photographed.

A digital zoom feature is similar to using an editing software program for images. In most cases, a digital camera may offer both types of zoom features. Most digital camera users recommend concentrating on the optical zoom feature to validate the quality of the device.

What to Look for In a Digital Camera

A digital camera generally has an LCD screen. This wide screen replaces the small aperture in conventional cameras through which you look into before taking the shot. The LCD screen allows the photographer to view the picture while taking it to see how it would appear in reality.

Digital cameras have memory stick slots where memory sticks are inserted. Unfortunately, memory is another major consideration that many consumers often overlook. For the most part it is because digital cameras that require larger memory can be quite expensive.

On the whole, many of the digital cameras of today make use of rechargeable batteries. Consumers should check if the particular brand they wish to purchase comes with a charger. If not, then you need to purchase it separately.

Downloading pictures taken with the digital camera is another factor that need to be considered. In most cases, many digital cameras can easily be connected to a desktop computer using a USB port. Through this connection, a user may download the pictures taken with the camera into the computer’s hard drive for printing or editing.

Apple iphone Facts

Here's what you need to know:


• We did a quick data test -- at our location we went from 104Kbps on the EDGE iPhone to 215Kbps on the 3G model. 2x ain't bad, yo.


• The enable/disable 3G setting is real, and buried a few menus deep. There is no automatic switching, Apple just assumes you'll leave 3G on, and that the iPhone has the juice to support that usage.


• It's tri-band 3G, as we reported the other day. This same phone will ship worldwide.


• WiFi is still 802.11b/g, no support for n yet.


• Yes, that GPS is A-GPS, just as we mentioned.


• Geotagging photos is a thumbs-up. We were deep indoors though, so native GPS wasn't working and we couldn't get a clear idea of satellite acquisition time.


• The screen looks exactly the same -- maybe a tiny bit brighter, but the unit was new, so it'd be negligible.


• The camera is identical to the first -- 2 megapixels. No front-facing camera (of course).


• It's certainly thicker feeling, but they rocked it Treo-style and really tapered those edges, so it just doesn't feel that different. But because of that curved back, it'll dance around on your table a little more than your completely-flat original iPhone.


• The plastic back didn't feel too cheap. In fact, it felt pretty solid. It's very glossy, so it'll pick up fingerprints just as well as the glass up front (yay).


• It comes with a ridiculously, absurdly small power adapter. It basically looks like a tiny square with a USB port on one side, and power prongs on the other. It will power any other iDevice (iPod touch, 1st gen iPhone, etc.), and sell separately for those that want a smaller adapter.


• The dock (now sold separately) and adapter (if you want an extra) will both go for something like $29, although that price is not yet confirmed.


• No mention was made of copy/paste, MMS, etc.


• It doesn't look like this thing is going to fit in your old dock. The new dock does look smaller and more sculpted to the new iPhone's curves.


• The headphone jack is flush, as mentioned. It's still 3.5mm, so if you don't like the out of box phones (which won't stay in our ears), bring your own, no problem -- and no adapter needed!


• Yes, original iPhones are totally gone, you won't be seeing those made anymore. Long live the aluminum back!


It looks like they took an amazing device and made it significantly better. If the battery life is as good as they claim, we think this will steamroll the competition in the enterprise space. And even if it doesn't, at $199 it's going to be extremely hard for people to resist.
