Some cameras allow you to partially depress the shutter button to temporarily "hold" the image in focus which somewhat eliminates that.

Nope that is something completely different Jeekinz. You are talking about focus. Most, if not all cameras work that way. You push the shutter button down halfway that that holds the focus point. That has nothing to do with the shutter speed. It is the long shutter speed without the camera being rock steady that is causing the blur, not the focus.

Right. But using that feature will produce clearer images when you're taking shots that require long shutter speed. Some people just fully depress the button, which causes a blur, and you don't really need to.

No that will not really give you clearer pictures unless the camera is already rock steady. You need to make sure it is perfectly steady (tripod and shutter release cord) otherwise pushing the shutter down half way wont matter at all. You could have perfect focus, but any movement of the camera, no matter how small, will give you blur.

I always press it down a little to focus, but I do also plan to get a tripod. I figured it was because of that--no way to hold it completely still. Sometimes though, I love to just get goofy and try for strange light shots. I have some on my home computer that I like better than these, but here are a couple. (Sorry to go so off-topic!).

Barbara, perhaps a little less caffeine is in order...

When using my camera in auto mode, pressing the shutter button halfway initiates the automatic setting of focus, aperature, shutter speed and 'film grain'?. After pressing halfway the instructions say you should press the rest of the way when the green light (indicating auto settings have been implemented) appears.
For example, indoors at 18:30 yesterday (with minimal room lighting), the auto settings resulted in photos being taken with the equivalent of a 1/6 second shutter speed, F2.8, and ISO sensitivity of 400. The composition of the picture consisted of a foreground distance of 4', subject at 14' and background at 24'. Focus was good to about 19'. The camera is an Olympus SP-570UZ.
Based on my experiences with target shooting it seems, the closer the subject is, the less critical camera shake becomes; besides some cameras have shake compensation logic.
