I think all it really boils down to is that digital zoom can be a convenient feature. While it may be better technique to take a full resolution image, then zoom in on your lcd preview to see if the part of the image you want to use is sharp enough, then upload it to your computer, edit it, and finally resave it, some people might prefer to just digitally zoom in, shoot, and print the photo right from their card.

Similarly, while it is generally considered better technique to shoot all your photos as 10mb RAW files, upload them to your computer, process them individually and resave them as JPGs or TIFs, some people would rather just shoot JPG and let the camera do all the work.

Finally, smaller file sizes can be a big deal to the less than technically savvy. It means less backing up to CDs and DVDs, not having to install more hard drives, and possibly being able to email your photos without having to resize them.

Many DSLR and digicam users are narrowly focussed on portraits or landscapes. Long zooms and augmented optical focal lengths are not usually preferred for either.

Users who use the long zoom tele at full or tele-conversion optical range often do so of necessity. For nature (e.g., avian) photography, "zoom-by-foot" is not often possible. Subjects don't cooperate. Even at max or auxilary tele zoom, subjects at great distance often occupy a too-small fraction of the image field. Unfortunately, many subjects move rapidly and unpredictably. Photo ops often lend themselves more to fortuitous grab-shots than to careful composition or tedious digi-scoping on a tripod.

For such commonplace non-ideal situations, there is a yet-unmentioned consideration. For a given final image size of the subject, the image quality may be about the same whether cropped in-camera or by post-processing. However, using the in-camera crop (aka, FL magnification), as with the FZ30, decreases the field of view. That makes it more difficult to locate a small subject at a distance in the narrowed field of view, to track subjects in motion, or to keep them within the field in burst-mode shooting to capture subjects in motion.

These considerations, as the ones offered above, also argue for image capture at full optical resolution and cropping for size and composition by post-processing. Simple image editors like Picasa2 ease such routine editing. More sophisticated edit control, by Photoshop or other hyper-sophisticated and specialized editors, is surely essential for large or fine-art prints, if not for e-mail, and for monitor viewing.

Default what a surprise ....

Wow - most of these answers surprise me very much! I've done a lot of research on this and have found out that good camera makers are currently able to implement very effective Image Stabilizers in digital zooms. Therefore the difference is HUGE!!! If you really need a closer shot and don't have additional optical zoom (with IS) - just use the digital zoom! The result will be so much better than cropping it later with any desktop software on a personal computer.

Additional benefits are the better exposure (because more specific to desired area) and the saved space on the memory card.

If you don't believe me - just try it out - you will be very surprised ... provided that you're using an adequate camera ...

Given the capabilities of the cameras when this thread was started, vs what today's models can do, you may very well be correct.

ive always found there is a balance needed. Never fully use the digizoom, but use post processing to that further degree you need.
But maybe its just my camera experiences, that after 20% they start to degredate the quality
