There were times when cameras were considered to be a rich man’s luxury but nowadays, clicking pictures with camera has become an important part of our daily events. With the constant improvement of technology, cameras have undergone a sea change and it was in the late 1970’s when digital cameras saw the light of the day.
The first digital camera was Sony Mavica, an analogue camera that used video floppy. However, since then, various brands launched digital cameras such as Nikon, Kodak Casio, JVC, Sony and Olympus to name a few. However, Canon Inc. Japanese MNC specialized in the manufacturing of computer printers, photo copiers and cameras. Canon started its operation in the year 1934 with Kwanon camera.
Ever since Canon started manufacturing its camera operation, it became a hugely successful company and a cynosure of camera lover across world. Presently, Canon digital camera is well known for its state of the art technology and advanced features that make it a well known brand name. Some of the high end Canon digital camera includes Powershot series like Powershot G9, SX 100 IS, S5 IS and TX1.
Canon digital camera EPH services include Powershot SD 950 IS, SD 890 IS, SD 790 IS, SD 870 IS, SD 770 IS, SD 1100 IS, SD 750, SD 850 IS, SD 800 IS and SD 1000.

Its basic features include image stabilization, auto focus, 2.5″ LCD display, Secure Digital Memory of 32 MB. Canon Powershot A590 IS includes image resolution of 8 mega pixels and optical and digital zoom of 4X, face detection focus, movie mode and manual and auto exposure along with 32 MB memory and 2.5: LCD screen.
Canon Digital Rebel XTi / Canon 400D comes with 10.1 mega pixel, file format of RAW and JPEG, DIGIC II processor, 9 point CMOS auto focus, micro drive support and automatic vibration and dust reduction.

There are a wide range of options and features available for DSLR (digital single lens reflex) cameras and it can be confusing if you are buying this type of camera for the first time. This guide will help you decide which features are important to you and hopefully help you to choose your ideal DSLR camera.
Price
A major factor in your decision is, of course, the price. DSLR cameras start at about $400 and can be as much as $8000 for a top of the range camera. A camera of between $400 to $1000 would probably be a good choose for a newcomer. Lenses tend to be expensive and can cost more than the camera body do make sure you take this into account when you make your budget.
Format Size
There are four format sizes at the moment for 35mm DSLR cameras.
Full Frame
This format, with a sensor size of sensor size is 36mm x 24mm, is found on most higher end cameras and is the same size as that used in 35mm film cameras.
APS-C
On a Canon camera this format has a 15mm x 22.5mm sensor and on a Nikon 15.6mm x 23.7mm. This format is used by most DSLR cameras except some higher end cameras and Olympus makes. Nikon call it a DX format.
APS-H
This format is only found in a few cameras such as the Canon EOS 1D MkIII and has a 18.7mm x 28.7mm sensor.
Four Thirds
This is a smaller format at 13.5mm x 18mm and is found on Olympus and Panasonic cameras. The aspect ratio is 3:4 unlike other cameras with an aspect ratio of 2:3.
All of the formats will give a good print out up to 11″ x 14″ which is the largest most amateur photographers will usually need. Most cameras below about $1000 dollars use the Four Thirds or APS-C format so the choice is usually dictated by the price rather than performance.
Image Stabilization Systems
Systems for image stabilisation vary between manufacturers. Some systems are mounted in the camera body others on the lens itself. Nikon and Canon use a lens based system and use gyros on the lens to sense movement and keep the optical groups stable. Gyros mounted on the camera body are used by Sony, Panasonic and Olympus in a stabilisation system called a sensor shift. The sensor shifts to compensate for any movement. Although both systems perform equally as well the lens mounted systems need to be included on every lens which adds to the cost. In addition not all lenses have the system included especially prime lenses under 200mm.
Size and Weight
Cheaper cameras tend to be smaller and lighter although, as no DSLR camera is going to fit into a pocket anyway, the size is not of primary important.
Pixel Count
DSLR camera start at about 6 mega pixels (MP) and can be as much as 22 MP for a high end camera. The pixel count will dictate the size that a print can be blown up to and you need to decide how large you would like your prints before you decide on which model to buy. 240 pixels per inch will give a very good quality print so a 6 MP camera will be adequate for a high quality 8″ x 10″ print.
If you need larger prints a 10 MP camera will be capable of producing a good print at a size of 11″ x 14″. A top of the range camera with a pixel count of 22 MP will give excellent 11″ x 14″ prints.
ISO Settings
ISO ranges between 100 and 1600 are found on most lower end cameras. Mid range cameras may have settings up to 6400 and a high end camera can reach as high as 25,500 and as low as 50. Most DSLR cameras will give pictures with low noise at ISO settings between 100 and 800 but the noise dramatically increases above this. The noise at the higher levels can vary considerably between models so, if possible, try to see images taken at higher setting with the cameras you are considering.
Noise
All digital images will have some noise which will be more noticeable at higher ISO settings. Noise comes from the electronics and sensor when the digital signal is produced from the analog signal. All DSLR cameras have noise filtering systems but this works less well above an ISO setting of about 800. Noise reduction softens the image so try to see images taken in low light if you will be using the higher range ISO settings.
Autofocus
Autofocus systems vary a great deal between manufacturers. All auto focus systems work well for static images but can vary a great deal for moving subjects, especially in low light. Check reviews of specific cameras for information on how well auto focus works for the model you are considering.

Just asking how much a Canon EOS 50d is in Hong Kong.
Also if the price is reasonable where do i get it?
THANKS
Considering the exchange (are you still using Hong Kong Dollars?)
it should be about the same, about $1,150 with a lens.
I’ve been to Hong Kong a couple of times, a beautiful place. I hope it’s not changed too much since 1997
