A complete guide to buying a digital camera

Upgrading your digital camera? Thinking perhaps of getting something a little better? Here are some points to consider before buying your next digital camera.
How many pixels is it?
This common question is at the heart of what most people think is important about buying or upgrading their digital camera. Buying a digital camera is par for the course these days. At the same time, however, the simple truth is that there appears to be a veritable labyrinth of technologies that you need to understand if you are going to get it right.
But is that really the case? What is it you really need to know? How do you buy the camera that is right for you and your family? A New Resolution
These days, cameras are not divided into the pixel count categories they used to be. Some of the smallest compact cameras have higher pixel counts than the larger cameras do.
For the sake of this article, lets divide our cameras into three common categories – Digital Single lens Reflex cameras (DSLRs), Prosumer cameras and digital compacts. Digital Single Lens Reflex cameras are those used by most professionals, the prosumer range are the all-in-ones, while compact cameras are those typically used by family snap shooters. Let’s start with the digital compacts. These little beauties are marvels of technology and the quality of image they achieve is quite remarkable. It only takes about 200 to 250 pixels per inch to achieve high resolution, so a 6 megapixel camera of 2000 x 3000 pixels can produce an enlargement 10×15 inches without any problem. These days, 6 megapixels or more is common for a compact camera. Some, like the Casio EX-Z1200, have 12 MP resolution!
So there must be more to the choice than just resolution. If pixel count was the only denominator, camera companies would simply increase their sensor resolutions and win the race. But it’s not that simple. The answer is in camera style, quality, features and control.
Cool Features
Photographers should want some control over their cameras. The kind of control and how much will vary depending on what kind of photographer you are. While technological advancements in metering and focusing have made our lives easier, they have not removed the fact that photography is an art as well as a science and control is a necessary part of the creative process. For this reason it is wise to first of all assess your needs as a photographer and analyse the kind of photographs you want to take.
Advancements in digital compacts however have been remarkable, giving the photographer much more than just improvement in image quality. Modern digital compacts are now offering the photographer a host of benefits and features. Functions like optical and digital zooms, manual focus options, close focusing, various picture modes and flash functions are becoming the norm among digital cameras. To add to this, there are also face and smile recognition modes, anti shake and much more.
Whether you need these features is up to you. Remember they will cost you a little more and so your purchase requires a certain amount of forethought and research. You need to ask yourself a few questions before you even enter the store.
What do I want this camera for?
What kind of photographs will I be taking?
What lighting conditions will I be taking pictures in?
Will I just rely on automatic or do I want to learn more about photography? • What am I like with technology and cameras generally? • What kind of features do I want and why? Do I need them, or do I just think they’re cool?
Does it matter to me what size and shape the camera is?
What can I afford?
These questions are a better basis for your decision than “How many pixels is it?†While this question is often the first one asked with reference to any digital camera, it is by no means the most important one. Not these days anyway. In fact, there is a point where pixel count can actually begin to negate quality rather than enhance it. This is because of something called ‘image noise’. This is the equivalent of grain in a film image. The sensors in compact digital cameras are very small, and the more photosites (the things that make pixels) there are crammed on to the sensor, the more potential noise the images can contain. So, pixels aren’t everything.
Other quality issues are important. Things like lens quality, colour, purple fringing, exposure accuracy, and sensor noise – all of these play a vital role in producing a quality image. You don’t need to don the white coat to sort this out. The real guys in the white coats have done most of that for you. But the attitude that pixels are everything is no longer correct. Actually, it never was.
Having it all
The next range of cameras up from there is what is commonly referred to in the industry as ‘prosumerâ€. They are called this because they fall somewhere between the consumer camera and the professional DSLR. These cameras are still relatively compact, but they view through the lens and usually have substantial optical zooms. The Fuji S8000fd is a classic example of this, sporting an 18x optical zoom that takes you from the 35mm equivalent of around 28mm wide angle through to an incredible 500mm telephoto! This is the kind of zooming power we used to dream of!
These cameras are simply incredible in their performance and their versatility. They are the kind of camera you could load into a back pack, travel the world with and never miss an image. They hover much closer to the $1000 mark than compacts do, but there is good reason for it. For more information on the three most popular models of this kind of camera, read Franco Darioli’s article “Three Way Race†in this issue.
Going Pro
The next range of digital camera to consider is the digital SLR. These are the ‘through the lens’ camera with the interchangeable lenses. Prosumer cameras see through the lens but by means of an LCD screen. Digital SLR cameras use an optical viewfinder which is not only easier on the eye but also more accurate. At
present, these cameras range from around 6 megapixels through to 21 megapixels and have a range of features that pit them so competitively against each other that it can be difficult to choose between them. Their price range is equally as varied, with cameras starting from around $800. From there, you can spend anything up to $10 000 or more. The advantage of these cameras is that their control and their readiness of operation. For professional and enthusiast photographers, these cameras are the natural choice. And, while they may appear frightening, they are actually as easy to use as any point and shoot camera you might buy. For this reason they are actually a better family camera than the traditional ‘family camera’ – the digital compact. But, the real advantage is that these cameras grow with you. Their ability to become professional picture taking
machines is all in your hands. They are more responsive, feel comfortable in your hands, and usually produce a higher quality image. Their sensors are not only laden with pixels, but are larger, and better engineered to produce images with less noise and less “purple fringingâ€.
If you are the kind of person who wants to make photography a serious hobby, a part time or full time profession or who simply wants the joy of a responsive, quality picture taking machine, these are the cameras for you. When you start out in photography you often don’t know what you will need – until you need it. If you have purchased a camera with limited ability to grow, then you may have to start again. This costs you time, money and photographs. Think carefully about this if the idea of photography as a hobby or profession seriously interests you.
Getting Real
In terms of visible quality in the average print, it is often impossible to tell the difference between images taken with compact digital cameras, prosumer models and DSLRs. That naturally depends on who is behind the camera and how well each photograph is taken. Each of the kinds of cameras we’ve discussed is capable of producing very high quality images. Your choice then has much to do with your personal needs, the nature of your photography, your desired growth (or not) as a photographer and of course, your budget. Before buying your next digital, think about these things first. Forget the ‘how many pixels is it†approach and think in terms of your photography. We buy these machines not because they are technological marvels. We buy them because they preserve our lives in little time capsules we call photographs. Think about that, and you will buy right.

Digital Camera Follows a Face and Retouches Using Software
New York Times, United States
Kodak is coming out with the Z1085 IS, a slim six-ounce camera with a 5X optical zoom and several built-in features to make snapshots look more professional.
In automatic mode the camera uses face detection and shake reduction to ensure that each shot is in focus. The face-tracking system displays a green animated box that follows faces in the frame. Once a shot is taken, software cleans up the image and reduces the effects of backlighting, which can darken images, or overexposure, which can wash them out
There are other scene modes for night shooting or taking pictures of fireworks or sunsets.
The Z1085 IS also takes high-definition video at 1280 by 720 pixels. Video can be recorded to the memory card and edited on a PC or watched on an HD television using an optional HD dock. The camera has a 2.5-inch liquid-crystal-display monitor and 32 megabytes of internal memory. It supports SD cards for memory expansion. It costs $250 online and in stores.
While the average Kodak user does not care about ISO or shutter speed, at least someone is thinking about — and tweaking — these functions using built-in software. JOHN BIGGS

Digital Camer’s To Get Cheaper As Market Grows
By David Richards | Sunday | 06/04/2008
GfK is forcasting 20% growth for the digital camera market in Asia Pacific in 2008 the predictions come as tradional CE brands like Samsung, Sony and Panasonic launch new digital camera products up against traditioinal camera brands such as Nikon, Canon and Pentax.
GFK Analyst Marion Knoche claims that there has been an unexpected growth in Digital Camera markets around the globe. 126 million DSCs were sold in 2007, representing 18% growth. The largest market was the US, followed by Japan and China. The most dynamic markets were in countries such as Russia and Latin America (Brazil, Chile and Argentina) as well as Australia with 54% growth.
The continuing flurry of new models entering the market combined with the ever increasing affordability of camcorders has led to a modest rise in global volume sales in recent months. February 2008 saw sales 5.9 % when compared to the same period last year.
From March 2007 to February 2008, sales units grew by 2.6% on the previous year according to GfK Retail and Technology. However value sales did not fare so well, falling by 9.4% over the same period.
Whilst falling average prices and the continuing popularity of competitively priced Mini DV models underline the reasons for this decline, two key catalysts capable of delivering value growth to this market still exist claim GFK.

Canon Crank Up Digital Camera Market
Smart House, AustraliaÂ
By David Richards | Wednesday | 02/04/2008
At a gala Sydney function complete with models makeup artists and props including a pure white dog skis a London telephone box and snow Canon last night rolled out their new IXUS digital camera.
With 40 million IXUS camera’s already sold this new compact shooter sets a new standard for digital camera design and is set to keep Canon at the top of the market. Under attack from brands like Sony, Samsung and Panasonic, as well as their traditional photo market rival Nikon Canon has turned to design to give them a competitive edge.
The new range is sleek with very few protruding parts other than a very stylish click button which also incorporates a zoom slider.
The IXUS 80IS is an 8.0-megapixel CCD camera with 3 xs Optical Zoom Lens. It comes in blue, camel, pink, and brown or silver and includes in-camera red-eye correction as well as has face detection technology.
Stuart Poignant Marketing Manager at Canon said” The Canon design team has worked hard to deliver a truly outstanding compact camera. In today’s market design and functionality are critical and our new range which is being rolled out behind a $2M marketing campaign is one of the best in the market today”.
Facing a hostile market with new competitors like Samsung snapping at their heels Canon are wary of the battle ahead particularly as consumers are transitioning from compact camera’s to a new generation of digital SLR cameras.
He recently said “The CE brands are licking their lips at the opportunities and the potential profits from the digital still camera market. Right now Canon and Nikon have around 80% of this market and the CE Vendors are going to have to lift their brand credibility to compete in this market. In 2008 the market will grow at around 30% to around 150,000 units and what we are witnessing is consumer upgrading from a compact camera to a digital SLR. They want a better picture and more creative control”.
He added” Going forward the market is going to get competitive and other brands have either got to increase share or get out. Currently the mass retailers are selling 29% of DSLR camera’s the specialist 50% and the rest are the traditional CE channel”.

Clean Your Digital SLR Camera’s Image Sensor
PC World
Zack Stern, PC World
Monday, March 24, 2008 10:00 PM PDT
If you look closely enough at photos taken with a digital single-lens reflex camera that’s been used for a while, you’ll probably see the dark silhouette of sensor grime. These opaque specks–the result of dust and detritus that has settled inside your camera’s body–can become recorded into photos, permanently fuzzing or blocking parts of the image.
Even if you never change lenses, dust can still drift into a camera body and land on the sensor, causing this speckling problem. And even bigger particles can easily reach the sensor if you do swap lenses. Some advanced digital SLRs now offer auto-cleaning modes that try to shake these particles loose. Such features help, but they’re often not enough to ensure blemish-free photos. Here’s how to manually do the job of cleaning your DSLR camera’s sensor–safely and effectively.
A number of DSLR cleaning products are available to choose from. Many of the kits can be overkill, including those with vacuums and other nice-but-unneeded tools. One optional extra I do like, the Delkin SensorScope, acts as a magnifying glass to identify debris.
High-end tools like these are convenient, but I’ll show you how to test the sensor without buying a $90 gadget. Instead, start with a basic swab-and-fluid kit before considering upgrades. I prefer the Photographic Solutions Digital Survival Kit because of its no-frills approach and low cost. Just be sure to pick the right version of a kit for your specific camera, because some fluids react badly with some sensors. Consult the kit manufacturer’s Web site to find the right kit for your camera. Also verify that the swab size matches your camera, so you don’t end up with something too big.
Get Started
Before you begin, it’s important to note that the sensor-cleaning process can damage your camera if you use the wrong tools. If you follow your cleaning kit instructions precisely, you should easily make it through without any problem.
But don’t clean the sensor if the lens is the real culprit. Use a blower to puff any debris off the front of the lens, and follow up with a nonabrasive cloth. Use the same technique on the inside of the lens, where it mounts to the camera. Liquid cleaners can damage lens coatings–never use an off-the-shelf household cleaner. If required, apply a cleaner that’s specially formulated for camera lenses.
Locate the Dust
Now, here’s how to test the sensor before cleaning it. In an area with lots of light, set your camera with as small an aperture as the lens allows. Focus on a blank, white surface like a sheet of paper, and use the aperture-priority mode so that the camera automatically sets the proper shutter speed. Fire some test photos to use as precleaning, “before” images. These will help you spot dirty areas on the sensor and will also give you a point of comparison after you’ve finished cleaning.
Open the test images on your PC, and zoom in at 100 percent to show one photo pixel per one display pixel. These photos should show the same even, white surface that you photographed.
Look for tiny, translucent droplets, dark specks, or thin lines. Clothing fibers, hair, pollen, and environmental debris can leave these marks. If they appear in the same position across all photos, a dirty sensor is the culprit. (If you don’t see any dots at all, stop here, because that means your sensor is already clean.)
Clean the Sensor
Activate the camera’s manual cleaning mode to flip open the mirror, and then remove the lens. Be sure that the battery is fully charged–or work with an AC adapter–because the mirror or prism will slam shut when the camera loses power or is turned off. You can damage the camera’s optics with your cleaning tools if they get in the way.
If you can clearly see something on the sensor, try to knock it off with air from a squeeze-bulb blower. Open a new sensor swab, and add two or three drops of the Eclipse solution to the tip. With a little sweeping gesture–gentle but firm–drag the swab laterally across your sensor. Twist the swab 180 degrees and drag it across in the opposite direction so that the clean side is leading the second pickup. Throw out the used swab.
Reattach the lens, and close the mirror or prism. Shoot additional test photos to see if you cleared out all of the debris. If not, repeat these cleaning steps until the sensor shines.
If you’re away from home–especially if you’re outdoors–don’t try to clean the sensor directly. Instead, puff a few gusts from a bulb blower into the camera without making physical contact. Save the direct cleaning for when you’re back in a controlled environment.
Keep the Sensor Clean
The best way to keep the sensor as clean as possible is to be mindful of your lenses. Swap these attachments quickly, keeping the camera body and both sides of the lens capped when not mounted together. If you have extra body- and lens-socket caps, lock them together in storage to block outside elements. The longer any one of these surfaces is exposed, the more likely it’ll gather grime.

Sigma launches new wide-aperture 50mm HSM lens
Digital Camera Reviews, OH
Sigma has done a one-up on the other wide-aperture 50mm primes on the market with the announcement last week of its 50mm f/1.4 EX DG HSM.
The company’s latest “fast 50″ sports Sigma’s ring-type Hyper Sonic Motor (HSM) focus drive, promising fast, near-silent AF operation and instant manual focus override just by turning the focusing ring. The EX pro-series lens also uses multi-layer coating to control flare and ghosting, and aspherical elements for aberration correction.
The new 50mm is slated for release in Canon, Nikon, Pentax, Sony, and Sigma mounts. No word from the maker on pricing or availability.
Sony’s new full-frame DSLR out in the open at Photo Imaging Expo
Tokyo hosted the Photo Imaging Expo 2008 late last week, and while there hasn’t been a flood of news from the show, apparently Sony’s planned full-frame pro DSLR that we reported on during PMA got a little more solid this week.
The photography blog masterchong.com posted several hands-on photos with the new camera (seen only under glass at PMA), along with shots of a new Sony external flash unit and battery grip to accompany the release. The new model, speculatively called the Alpha A900 and targeted squarely at pro bodies from Canon and Nikon, utilizes a newly developed 24.6 megapixel CMOS sensor.
Reports from PIE have confirmed that we should expect final versions of the A900 to make an appearance in time for Photokina in the fall.
Check out the images at masterchong.com.
