I have the Olympus Tough 8000 (the newest of their waterprood, ruggedized line). I have a digital SLR (Nikon D80) that I had not intention of bringing on the trail. Even though the D80 takes an excellent image, I just wasn't willing to carry the weight for my whole thru.
As I am want to do, I did lots of research before buying the Olympus. I poured through reviews and talked to many people (mostly non thru hikers). I knew there would be trade-offs with any compact camera. The Olympus has widely been panned for its image quality. Part of this is caused by the bent optics it uses in it’s ruggedized design. Instead of an extendable lens, the whole lens is contained within the camera body using mirrors and a bent light path.
The only way I’ve been able to get images I find acceptable on the Olympus is to deactivate the auto iso setting, and force the camera to a low iso number (say 100, certainly no more than 200). Unfortunately this doesn’t work in every camera mode, so you won’t be able to do this in every mode. In any camera one will find image quality decreases at higher iso setting, but the decrease in image quality on the Olympus is much more noticeable than in other cameras. One other drawback, the Olympus isn’t as light as some of the lightest compact cameras.
On the up side, the camera is very durable. If you drop it, it is designed to take the abuse. As for waterproofing, I’ve taken both pictures and video with it underwater. The Tough 8000 is rated to take pictures down to 33 feet under water for up to an hour. The underwater pictures are surprisingly good.
Among other contenders, a waterproof or water resistant Pentax compact digital was recommended to me, and although not directly recommendeded to me by anyone I seriously considered the Sigma DP1. The Sigma DP1 takes fantastic pictures for a compact, and it can use screw on lens extenders. On the downside, it is a little heavier, certainly not waterproof, and expensive.
My ultimate rational was, most of the pictures I take while I head north will be of people, and any landscape shots I’m not happy with, I can always come back and reshoot with my SLR if I really want to.
I also considered taking my Olympus Infinity Stylus Epic. It is a great waterproof, semi-ruggedized compact 35mm camera that takes fantastic pictures. It has a good quality fixed length F2.8 lens. As it doesn’t have a zoom, they never needed to create an internal and extendable bent light path for the optics, and as a result, the image quality isn’t put at risk. I carried this camera hiking for years. I just wasn’t willing to add 35mm film as one more item on my resupply list. Plus, using an xD card adapter and an 8gb MicroSDHC card in the Olympus I have room for more photos than I could realistically take.
