Questions To Ask When Buying An Slr Digital Camera
In a world of low-priced cameras, it is good to know that are also options for people who take their photography seriously, but don’t have thousands of dollars to spend on a camera. For these photography “purists”, there are SLR Digital Cameras. SLR means Single-Reflex
Camera and the digital versions of these cameras allow the individual to take high-quality pictures using a variety of different lens types.
The following are some important questions that every one considering a digital SLR camera should ask before making this exciting purchase.
Auto-Focus or Manual Focus?
Auto focus SLR cameras provide you with a tremendous amount of convenience when it comes time to snap your picture. However, there are several drawbacks to auto-focus cameras, including:
• Auto focus systems are run by electronics, which can fail you at the worst possible time
• Auto focus cameras burn through batteries faster than manual focus models
• Auto focus cameras can be noisy
• Sometimes the lasers that control auto focus lenses see things differently than they human eye
Individuals who like additional control and customization options may wish to choose a manual focus camera. Manual focus SLR cameras allow the user to control shutter speed, aperture and the zoom focus features. Disadvantages of manual focus cameras include the steeper learning curve and the additional time it takes to properly set up each shot.
Can you auto-preview pictures with a digital SLR camera?
Yes. Digital SLR cameras offer all of the convenient features found in standard digital cameras, including the ability to preview pictures on the camera’s screen, cycle through photos and delete unwanted images and easily transfer photos onto a memory card or computer.
What are the Most Important SLR Camera Accessories to Buy?
Everyone who takes their camera on the road with them should have an extra battery always on hand. (NOTE: Be sure to keep your spare battery properly charged at all times.) Also, a neck strap helps you keep your camera handy while on the go. Finally, a tripod is a great choice for anyone who plans on taking posed or stationary pictures with their Digital SLR.
What are Gray Market Cameras?
When you a buy a Digital SLR camera online or at a traditional camera store, you will either be purchasing a gray market or warranty-covered camera. Both are the actual manufacturer’s product, but gray market cameras are generally not covered by a warranty (and are less expensive as a result).
How much do Digital SLR Cameras Cost?
Digital SLR cameras are available at a wide variety of price points, from $400 to $5000. The price of the camera depends upon the features included and the zoom capability of the lenses. Price may also be dictated by the lens package included.
How much Memory is Required?
Although the amount of memory is a personal choice, experts agree that a one gigabyte card is the most appropriate place to start. A one gigabyte memory card will hold hundreds of even the highest quality images comfortably.

Q: Why do I need a Digital SLR while most digital point&shoot cameras have manual settings for ISO & aperture?
I am planning a trip to Tanzania safaris. A digital camera is no brainer. However, considering between a digital SLR (dSLR) and a standard digital point & shoot (P&S) camera, I find it hard to justify the cost of dSLR.
Film SLR’s provided 2 advantgaes over P&S cameras: a) interchangeable lenses and b) WYSIWYG pictures.
With P&S cameras advancing so much these days, we get P&S cameras that have zoom ranges longer than 400 mm (e.g, considering the 1.6x differential between the 35 mm format and the digital CCD format, a standard 10x optial zoom in a typical P&S digital camera gives you a zoom of about 400 mm). With image stabilization added in P&S cameras, I do not see a distinct advantage with dSLR’s.
So, if I choose a P&S camera that has:
1) 10x or longer optical zoom
2) image stabilization
3) manual settings for ISO, aperture, and shutter speed
4) fast lens at higher zoom ranges
5) minimum shutter lag
Why would I need a digital SLR?
There are a few more advantages to a digital SLR:
A dSLR is vastly more responsive than a compact. With a dSLR, you press the shutter button and the camera fires. With a compact, the electronic viewfinfer has a delay, and when you press the shutter button you get another delay – without exception, they’re terrible for up close action.
With a dSLR you CAN get fast lenses. Fast autofocus AND great in low light. For $1600 you can get a Canon or Nikon zoom that effectively does 105-300mm tack sharp at f/2.8. With a compact, you’re probably looking at f/5.6 … and you probably need to stop it down to f/8 before it delivers decent image quality. If you’re out at dusk, that could make the difference between getting a few crisp shots, or waiting for the autofocus to get a lock only to discover that your shutter time is impossibly long.
With a dSLR you can set the ISO to 800 and get good image quality. In a pinch, you can crank the ISO up to 3200. With a compact, ISO 400 is usually pretty poor, and you’re lucky if it goes higher at all. Again, a great advantage in low light situations.
With a dSLR you get better continuous shooting. With the entry level models you get 3fps for about the first 8 shots and the buffer clears quickly. With my Nikon D200 I get 5 fps at 10 megapixels for 22 shots before it starts to slow down. Top of the line models do 8+ fps.
All of this extra performance comes at a considerable finanial price however. On the other hand, you could rent the gear, or sell your gear after the trip at only a small loss. Another down side is that a dSLR setup can get pretty bulky and heavy – no problem in a jeep but I’d hate to hike 10 miles with it.
