My only semi-complaint is that when on the highest quality settings, the movie mode used a TON of space on my memory card. A 90 second video took up almost 300MB! Although that is way too large for a video that short, I have still left it on the highest setting because I don't want to sacrifice any quality (especially when these videos involve giant sea turtles). Also, optical zoom is not available during video; it is purely digital zoom.
And finally, my favorite mode on this Pentax Optio W90 12.1 MP Waterproof Digital Camera is the underwater picture/video mode. I used it while snorkeling in Hanauma Bay and took stunning pictures and videos of tropical fish, giant sea turtles, squid, and so much more. With my goggles on, I could easily see the screen of the camera and had no trouble change modes while underwater. It was just as easy to operate underwater as it was above water. I was surprised to learn that the microphone actually picked up sound underwater. You could hear me breathing through the snorkel and if there are people yelling nearby, you can still hear it underwater. My only problem was that when there was a lot of sand floating in the water, the camera focused on the floating sand instead of the turtle behind it. But this only happened when I put my feet on the sand, which probably kicked it up into the water. So be careful about that.
Three pieces of advice on Pentax Optio W90 12.1 MP Waterproof Digital Camera:
1. After Pentax Optio W90 Waterproof Digital Camera has been submerged, let the camera sit and dry for at least an hour before you open it (even if you dried it with a towel yourself, still let it sit for an hour) because the area right outside the internal waterproof seals cannot be dried without opening the camera and exposing the battery to that small amount of water.
2. ALWAYS TURN OFF THE FLASH in auto mode unless you absolutely need it. This camera tends to flash when it isn't necessary. The first thing I do when I turn this camera on is turn off the flash.
3. Turn the picture quality to the highest setting as soon as you turn on this camera! It is not on the highest setting by default. You can also do this for videos, but I warn you that the high-quality videos will eat up your memory card space. But for me, it's worth it.
I also recommend the floating strap for this camera.Pentax Optio Floating Wrist Strap for Cameras
