Katesdad:
I have access to a Nikon N90s with 35-70 2.8 and 80-200 2.8ED
I also have access to a Nikon D1 with the same lenses and a 24mm since the digital format requires a wider lens. Last cruise (10 years ago) I took the full rig and got some great pics. So what, you ask, am I taking this time?
A Canon Elph 330 (The size of a pack of cigarettes) and a Sharp mini-dv Viewcam (The size of a paperback book.) A couple of extra tapes, a 256MB compact flash card, and a couple of extra batteries. The whole setup fits in a medium fanny pack with plenty of room to spare. The SLR body and one lens wouldn't fit comfortably in this bag.
My reasoning is this: With the Elph at max resolution, I can get 407 pictures, printable with minimal loss up to 8x10 on the one card that stays in the camera. (No film to carry around, try to keep cool, keep from x-ray damage, get wet etc...) The only reason to bring the big stuff would be if I intended to make lots of 11x14 or larger prints. I can e-mail the pics from the Elph to
Walmart and pick them up at my local store a few days later for 26 cents each. And since I will delete anything I don't like, I will only print the ones I want.
To see a pic from the Elph, go to
www.geekteach.net/pics It's just a picture of the brick sidewalk and step I built on the front of my house, but you can get an idea of the picture quality. (Sorry if it takes a while to load. My upload speed is slower than my download)
The camcorder is capable of shooting stills in a pinch but doesn't have near the quality. You could make a 3x5 off of it but no bigger. I bought the Sharp because of the rear mount screen. I am blind in one eye (I know-getting photo advice from the blind guy

) and of all of the camcorders with screens, the Sharp is the only one with the buttons in the right place to make the screen useful for recording. When I put a small eyepiece up to my eye, I can't see what's going on around me. With a 10 year old, I think the camcorder is a must. Pictures of him parasailing at
Castaway Cay won't capture the joy/fear as well. I bought mini-dv format because the tape resolution is better, the tapes are smaller, the camcorder is smaller, and 1 hour per tape makes it easier to find what I'm looking for when I play them back.
Sorry I ran long. I hope it helps.
