We have a couple of Pentax Kx's but we rarely take them far from the house. We have learned the hard way that if we take them outside as much as we go outside, they won't last a year in this
environment. We step out on calm days to get sunsets, etc. Even so, dust on the image is a huge problem. It's easier to deal with in post processing than to keep opening the
camera up and trying to clean the sensor. I use Corel Paintshop Pro for the processing because I am comfortable with it and I don't need all the photoshopping capabilities of the Adobe products. I don't move pixels around, as I think that would be 'dishonest' in most cases. I do use the
software to remove haze, sharpen, and of course, crop. In the case of the dust spots on the Kx
images, they tend to be on the top edge of the photos and mostly obvious in photos of sky or clouds. I can usually crop them out.
If you've seen our blog you know we have thousands of tropical,
boating, underwater photos. I've been through 8 cameras in three years. I've been through a Kodak, three Sony's, three Olympus...
Right now, I am shooting with waterproof only. Got too expensive otherwise.
I have a little Pentax Optio W-80 that goes in my cargo pocket shorts with me everywhere and I have an Olympus Tough 8010 that I use in an underwater housing for our boat and
diving stuff.
This is my third Olympus, after the SW 7710 and 1030. I got a year each out of those 'waterproof' point and shoots. I learned that in Asian
marketing lingo, 'waterproof' actually means 'splash resistant'. But by putting the waterproof Oly in an underwater housing...so far it's working. Belt and suspenders. I don't particularly like the Olympus. It's way too slow. You miss a lot of shots with it, waiting for it to boot up, or to get ready for the next
photo. Frustrating. Does good movies, though, and it's rugged. That's about all I can say for it.
The Optio is pretty good, and the cheapest waterproof point and shoot of the lot. It's biggest drawback is no lens cover. constantly have to watch for smears, dried
salt, etc.
I looked at the Canon, and I LIKE Canons, but theirs is just too bulky to drop into a pocket.
I am really keen on the new little Nikon, though. Might buy one of them next trip to the USA next month.........to look at catamarans for sale!!
