Canon Powershot A540
The CANON POWERSHOT A540 was launched in the market after A510 and A520. These two models have been replaced by the CANON A530 and A540. There are a lot of features in A540 which are absent in the other three mentioned cameras.
The CANON A540 has a 6megapixel camera with 4x optical zoom whereas in the regular ones there is 3x optical zoom. Thus this camera is better than the other ones. There clicked pictures are displayed on the 2.5’’LCD display with 85000 pixels and the results are outstanding. There are provisions for editing and retouching of the pictures. There is a new function of face brightening which brightens up the faces of the people whose picture has been clicked. In the normal camera the brightness can be increased but of the entire picture and not only the face. So this is an amazing feature in the CANON POWERSHOT A540.
The CANON A540 ISO speed is from 80 – 800. The CANON A series has a DIGIC II processor which increases the speed of the camera startup, clicking pictures and playback. Thus it increases the overall efficiency of the camera. The DIGIC II processor consumes 35% less power than the previous DIGIC chip which increases the battery efficiency of the camera. The CANON A 540 is powered by two AA size rechargeable Ni-mh batteries. The Ni-mh batteries last for approx 350 pictures that is very good. Thus the camera gives greater results with greater efficiency.
The CANON A540 Dimensions are 90.4 x 64.0 x 43.2mm (l x b x h). The Camera weighs approx 180 grams which is light while holding and thus it is easier to click pictures. The CANON A540 can be connected to the computer by using the USB 2.0 high speed connector with PTP i.e. Picture Transfer Protocol with which you can transfer the pictures to the computer. There are different playback modes in the Canon A540. They are Single (histogram displayable), Index (9 thumbnail images), Magnified (approx. 10x (max.) in LCD monitor, advance or reverse through magnified images possible), Auto play, Sound memos (up to 60 sec.) or Movie.
The CANON A540 records sound in WAVE format, images in JPEG and movies in AVI format. It also has options for compression of the files. The options are superfine, fine and normal. The data on the camera is stored on a SD or MMC i.e. Multi Media Card. There is also self timer on the camera which delays the clicking by 2 to 10 seconds.
When you purchase the CANON A 540 you get A 6.0 The 6.0 effective Megapixel PowerShot A540 digital camera, 16MB Secure Digital card, Two alkaline AA batteries, Wrist strap, USB cable, A/V cable, CD-ROM featuring Canon Digital Camera Solutions, ArcSoft PhotoStudio, and drivers, 24 page basic manual + 137 page advanced manual (both printed). The CANON A 540 price is approx Rs.12,000/-. The features are good undoubtedly but the price tag which this camera has it does not deserve it.
