Which camera I should buy??

Oh boy!! On popular demand. This is tough one but explanation is easy.  Its all 3 :)
- There are 3 type of camera in digital format. (SLR - Single light Ray, Micro 4/3, Point & Shoot).
- There are 3 type of usage: Low light, Day light, Mix light.
- There are 3 type of customer preferences: Cost, Weight, Quality. Obviously all want least cost, least weight and highest quality.
- There are 3 type of lens (Wide, Normal, Zoom). Any camera offering wide to zoom will be rich in feature but not very fine in optical quality simply by design. Canon SX series leads in super zoom category.

- There are 3 parameters:
1. Aperture: Its opening to decide how much light should go in at once, good for low light, more opening is indicated by lower number. F1.4 is more aperture than F1.8. Factors are (f1.4, 1.8, 2.0, 2.2, 2.8, 3.5). Costliest and most desirable lens are of high aperture (not to mention they support no aperture anyday). Only micro 4/3 and slr type camera offer you to change the lens type. Canon S90 has bigger aperture lens in point & shoot category too (but only on wide side).

2. Shutter Speed: It decides for how long light will go in. Faster means action freeze. With kids & sports you mostly want fast shutter speeds. All camera are good from this point.

3. ISO: Most important these days, its sensitivity of sensor which higher is more desirable but higher also means more grains. Hence camera should be able to reduce that. It comes in factor of 100, 200, 400, 800... etc. Each one doubles the sensitivity. Point & shoot don't go without grains above 400 and SLR goes to 1600 sometimes.

Now verdict:
SLR: They offer best quality and freedom to switch lens but are bulky and costly. Least on feature like video, wifi but manual controls are best.
Micro 4/3: Offers freedom to change lens, compact and manual controls are good, picture quality not as good as SLR (nick pick). - value of money.
Point & Shoot: Compact, super zoom and good ones fall here, select based on your preferences and your understanding of material written above.
