Aperture and Shutter Speed Relationship

I'm new to photography and, like many others on this forum, I have purchased a G2 and started learning. This forum is an amazing resource - keep it going.

Anyway probably a basic question.

I have noticed that when using a large aperture i.e F2.0 the maximum shutter speed is restrictred to 1/500 but using smaller aperture settings i.e F8.0 faster shutter speeds are available - 1/1000.

Why is this?

I think you have got that the wrong way round.
Think of it this way..the shutter speed controls the amount of light hitting the sensor ..the aperture controls the quality of light or the amount of (in focus) area.For a scenic shot where you want most of the image to be in focus you would use a larger Fstop F5-F8.
For a portrait or where you want to seperate the subject from a distracting background by putting it out of focus you would use a small Fstop F2.5.
I know this is confusing but the aperture at F2.8 is wide open like the pupil of the eye in low light situations,whereas the aperture at F8 is closed down thus giving you better quality light.

To get back to the original question..you have to juggle the two settings in order to get the best exposure for your image.if using F8 there is less lighting hitting the sensor and so the shutter speed has to slow down in order to let in enough light for a correct exposure.
Conversly if using F2.5 there is plenty of light coming into the camera thru the larger hole/aperture and so that means that you can have a faster shutter speed which is useful for action shots or for when you are hand holdng the camera without getting camera shake which will affect the quality of your photos.
Hope this is not too confusing.

Thanks KK that's how I understood it. What confused me was on page 65 of the user manuel it gives the maximum shutter speed at only 1/500 for F2.0-3.2 but if you decrease the appeture to F8.0 the maximum shutter speed the camera allows you to set is 1/1000.
I just couldn't understand why that should be so.

Sorry about that Fellrunner.
From your intro I presumed you did not know anything about DOF etc.
Yes I have just looked at the manual and you are of course right.
Dont ask me why tho'.
Maybe it has something to do with the algorithyms they use for CCD sensor.
Does that sound like I know what Im talking about?
I wouldnt have a clue!

PS FellRunner is that something to do with long distance running in the UK?

I do not know either -- but -- I forgot about the manual and see what trouble that leads to in:
