You won't see any substantial difference when you compare seven-, five- and three-megapixel images, all of which the EX-Z75 allows you to take. Obviously, the more pixels you have the bigger you can print an image without losing detail and quality, but you could easily drop down to five-megapixel and save a megabyte on the size of a Fine image and print out standard sized pictures through a decent high-resolution printing service without being able to tell any difference with seven-megapixel images.

A nice touch with this compact is that not only can you delete one image at a time, you can delete all of them in one go: a handy trick that saves you negotiating the complex settings screens to reformat your card and the camera's own memory.
Inevitably, the EX-Z75 incorporates image stabilisation technology to counter camera shake. This is a tricky one to assess - after taking pictures long enough to be able to hold a camera reasonably steady, we think, we found that when taking considerable care, images on the Casio were not any sharper than comparable pics snapped on an old Cyber-shot for example, which has no image stabilisation system.
Still, it could cope with deliberately shaky hands much better, and while the images weren't perfect - the Casio won't eliminate excessive shake - they were much better than those taken the same way on the Sony.
Pushing the power button gets the camera ready to take pictures in a smidge over a second; certainly less than 1.5s.
I just got...
...a canon IXUS 850 IS, this is 7.1mpix too and you can get a water proof case that goes down 40 Meters, and this camera has an optical view finder. (lovely camera btw :) )
A little different?
"How do you sell a seven-megapixel camera when so many rivals are doing the same? You can't rely on the usual features - big LCD, anti-blur tech, slimline metal casing, etc - because everyone else has those too. No, you need something a little different, and in Casio's case that means offering your latest compact camera with an optional underwater kit."
Pentax and Olympus already sell p&s cameras that are waterproof down to a couple of meters, and you can get casings for many other p&s's. Nothing new here then...
Re. How Deep?
It goes down to 3m (10ft), apparently.
How deep does it go?
There's no mention of how deep the waterproof case will go, despite you giving a page of the article to this accessory. There's nothing on the makers website either (not helpful, but not your fault). Is it for pool use, or suitable for diving? Its also helpful if you can confirm any waterproof rating for guarantee purposes as opposed to the legally useless "water-resistant"
I've had three of these...
On one, the flash failed within the first week. On the second, the flash failed after a month and it had a poor USB connection, so half way through importing photos, it would just disconnect. The third one is going okay, but I don't know how long that will last.
