Tips in buying a professional dslr

Professional DSLR cameras are not for the casual photographer. They are designed for hard rain or shine shutterbugs that refuse to leave the house without a camera. And although these advanced cameras are more expensive than most digital cameras, they are a great investment in the long run.
Here are some benefits to owning a professional DSLR camera:
  • More creative control: These cameras include a broad array of manual settings, allowing the photographer to frame the picture exactly as they want it. True shutterbugs would never settle for auto focus and automated aperture and ISO settings. Although many point-and-shoot cameras have similar manual settings, these features are limited.
  • Faster shutter speed: All digital cameras have shutter lag, the time between pressing the button and the camera capturing the photograph. These image capturing devices have a significantly shorter shutter lag than point-and-shoot cameras.
  • Interchangeable lenses: Interchangeable lenses provide the photographer with more versatility.
  • Viewfinder for better framing: Looking through a viewfinder opposed to an LCD screen provides for better framing.

Professional DSLR Cameras: What to Look For

Professional DSLR cameras are an expensive investment for professional photographers and amateur hobbyists alike. DSLRs should contain the latest technology and provide the photographer with ultimate creative control. In addition to analyzing the features and functions of a DSLR camera some additional criteria we suggest looking into when purchasing a professional grade camera includes price, lens selection and compatibility, and longevity. These are the features TopTenREVIEWS used to evaluate professional DSLR cameras:
  • Design
Traditionally, these image capturing devices are heavier and bulkier than point-and-shoot cameras; however, their size and weight should remain reasonable. The size of the LCD display screen and the overall design of the camera's body should be taken in consideration. The ability for the device to record images in HD format is also a desired feature. This technology is not available in every DSLR camera.
  • Image Quality
Resolution is measured in megapixels. The more megapixels a camera has the better quality prints it produces. These advanced cameras need more megapixels than point-and-shoot cameras because it gives the photographer more creative control in the editing and printing process.
  • Battery Life/Memory
Professionals especially rely on their cameras to capture others' memories. The best professional DSLR cameras will not suck the life out of batteries after only a few shots. The memory available must allow for enough data to be stored for a large quantity of photos. Removable memory is also an added feature and makes it much easier for transferring files from the device onto a PC.

Canon EOS 1000D / Rebel XS

Sensor: 10.1 Mpixel CMOS / 22.2x14.8mm
Image size: 3888 x 2592 pixels / 3:2
Lens bundle: EF-S 18-55mm IS (x1.6 coverage)
Screen: 2.5in, 230K pixels
Memory format: SD / SDHC
Size: 126x98x62mm
Weight: 450g (body ex battery)

The new EOS 1000D / Rebel XS replaces the EOS 400D / XTi as the entry-level model in Canon’s range and sports the same 10.1 Megapixel resolution, 3fps continuous JPEG shooting and 2.5in screen. The big new feature is Live View, although the 1000D / XS is also Canon’s lightest DSLR to date at just 450g. Beyond this, the 1000D swaps its predecessor’s 9-point AF for a 7-point wide area AF system and Compact Flash cards for SD memory.

Canon EOS 60D

The Canon 60D is only slightly smaller than its predecessor, the Canon 50D, and is targeted at the advanced amateur market.
Its body has a special conductive fiber that is presumably used for EMI (electromagnetic interference) shielding and its frame is made of aluminum and polycarbonate enhanced with glass fiber. It also has a more textured body and smaller grip which mostly makes it more comfortable to hold in your hands, depending on hand size.
The Canon 60D features an all-new versatile tilting and swiveling vari-angle 1,040,000-dot LCD screen, allowing users to easily compose shots that were once thought virtually impossible. While Canon’s past vari-angle swivel mechanisms have not felt too solid, this one seems to be a winner with smooth movement and resistance stiff enough to stay put. Also, users will find the largely absent infrared remote control window on this new camera, together with a new mono microphone and a stereo microphone jack for better quality movie recording.
On the top of the camera, users will find a highly-controversial locking Mode dial that in my opinion, is extremely useful once you get used to it considering it prevents you from accidentally changing the exposure mode. In addition, the new 8-way control wheel is certainly an improvement over its fellow Canon siblings, making its menus more user-friendly and easily accessible. Also, the LCD on the top is no longer rectangular but tapered with a visibly smaller flash size.

Features

The Canon 60D sports a 18.0-megapixel APS-C sized CMOS image sensor with a 1.6x focal length crop and shoots pictures up to a maximum size of 5,184 x 3,456 pixels.
Its DIGIC 4 image processor is similar to its predecessor, the Canon 50D but with its increased resolution, the Canon 60D’s burst shooting speed is only 5.3 frames per second, down from 6.3 frames per second on the Canon 50D, while maximum burst depth is largely unchanged at 16 RAW images or 58 large/fine JPEG images.
This new release from Canon has an ISO range of 100 to 6400 with the ability to extend to ISO 12,800 and offers an Auto ISO function. It also features a 9-point diamond array AF sensorAF modes include One-shot, Predictive AI Servo AF and AI Focus AF. Unfortunately, the Canon 60D does not have the Lens AF Microadjustment custom function that is found on the Canon 50D and Canon 7D. This feature allows users to tune the camera’s autofocus to compensate for lenses that back or front-focus. with 9 cross-type f/5.6 AF points and an ability to detect the light source, including the color temperature and whether or not the light is pulsing.
The Canon 60D has a wide range of exposure modes that are divided into 2 distinct groups – the Basic and Creative zones. Basic exposure modes include the Full Auto, Flash Off, Creative Auto, Portrait, Landscape, Close-up (Macro), Sports, and Night Portrait modes while the Creative ones comprise Program, Shutter-priority, Aperture-priority, Manual, and Bulb.
Another notable feature on this Canon DSLR is Canon’s latest metering system that is seen on its recent releases like the Canon EOS 7D and Canon EOS Rebel T2i. The Canon 60D now sports a 63-zone iFCL (Intelligent Focus, Color, and Luminance metering) sensor. With this sensor, the iFCL chip has a dual-layer design with each layer sensitive to different wavelengths of light, allowing subject color to be taken into account when determining exposure. Information on focusing points is also taken into account in metering calculations.
Other features include Live view, built-in flash, an eye-level pentaprism viewfinder with improved 96% coverage and magnification of 0.95x and shutter speeds that range from 1/8,000 to 30 seconds and a bulb position with the electronically controlled, vertical-travel, mechanical focal-plane shutter that has a rate life of 100,000 cycles.
In movie mode, the Canon 60D features both Program auto and Manual exposure control and even allows the use of autofocus during movie recording.

Performance

The Canon 60D is quick to start up and is ready for action in less than a second. It also performs well in low-light conditions even though there is a slight delay in focusing speed when using the Live View mode to take pictures.
In my opinion, the main drawback would lie in its slow speed when focusing on moving objects, while Quick mode offers users a speedier autofocus option.
When it comes to picture quality, the Canon 60D produces fine, crisp images both in JPEG and RAW formats under good sunny conditions. Image taken in RAW format were also noticeable sharper and better when the ISO level was cranked up. This is thanks to the Canon EOS 60D’s extended ISO 6,400 levels which make it more effective at taking pictures under low-light conditions.
Coming to HD videos, the Canon EOS 60D records 1080p videos at 25fps and 720p videos at 60fps. The video quality is impressive with overall great video quality, even when recording indoors or in low-light conditions.
