Suggestion please..

Thanks for ur reply.

Between Canon SX120IS, Sony H20 which is better in terms of image quality at both modes(indoor and outdoors).


There are some terms that I couldn't understand, please tell me about the below terms :

Image ratio w:h - 4:3, 3:2 Vs 16:9, 4:3, 3:2
Aperture range - F2.8 - F4.3 Vs F3.3 - F5.1
min shutter and max shutter speed.

Thanks

Image Ratio - also know as - Aspect Ratio
It gives the shape of the picture it can produce.
The ratio between the longest side and the shortest side.

i.e. - 1:1 would be a perfectly square picture.

4:3 is the normal rectangular shape of a picture from a small digital camera and also the shape of older TV set screens and older computer screens.

3:2 is the rectangular shape of a picture from most DSLR (digital single lens reflex) cameras and 35mm film.

16:9 is the rectangular shape of a picture that will match a HD (high definition) TV screen.

....

Aperture Range - Gives you the range of Aperture settings for a particular lens.
f/2.8 is the brightest setting when you are using zero optical zoom.
f/4.3 is the brightest setting when you are using maximum optical zoom.
In other words - you lose light when zooming the lens.
Therefore, it is better to use no Zoom when inside and not using flash.

The difference between the two lenses shown is about 1/2 of a f-stop.
Which means - not enough difference to matter.

Here is a link that tells all about Aperture:

min shutter and max shutter speed:

Maximum shutter speed is the fastest shutter speed the camera can produce.
1/1000th of a second is fast enough for most normal photography.

Minimum shutter speed is the slowest shutter speed the camera can produce.
A setting of 15 means the shutter stays open for 15 seconds.
Slow shutter speeds occur when you are taking pictures in low lighting conditions (without flash).

You are obviously looking at a specification chart from dpreview:

A tip: Notice the yellow question mark on the same line with most of the camera terms.
Click that yellow question mark for a brief explanation.

Tip #2: Notice the small chart on the far top left of the dpreview page.
Click on Learn/Glossary
That will lead you to explanations of almost all photography terms and buzz-words.

Thanks for the useful information.
This will help in chosing the right cameras and also inspires me to learn and explore about photography/camera.
