Go shoping with your bike gloves and your sunglasses. My comments about bike touring cameras come down to:
1. You must like the software. If you can't talk to the camera, none of its expensive features were worth what you paid.
2. You must be able to use the controls. Can you work the camera with your bike gloves?or sunglasses?
3. Can you get batteries for it on the road or charge it?
4. Have a safety lanyard. I've seen people go down trying to catch a fumbled camera while riding. Camera and bike and rider all got banged up.
5. Get a protective case.
6. What will you do with the image files? An offloader? If you put an 8G card in the thing and store two months' worth of photos and someone steals your camera your vacation is gone.
7. Waterproof is unnecessary unless you're a diver.
8. 12mp is unnecessary. 90% of your images will be emailed or uploaded as wee jpgs.
9. Don't buy anything you can't afford to lose, break, or have stolen. It's not jewelry, it's just a camera. Good glass is more important than sensor density.
10. Remote? All you need is a self timer.
That all makes a lot of sense, although I realize I didn't mention the reason for the photos in the first place. I do hope to get nice photos that I would then design into a book (I am a graphic designer). Also, the reason for the higher MP is for upload onto a site called iStockPhoto.com, which has a high standard. I don't think the Pn'S are up to par with what I am looking for.
Now the question for me is whether I want to add my photography hobby and idea for a book to my trip. I did read the "photography and biking do they mix" thread and so it causes questions for me.
I am finding there are endless questions that need to be answered for cross country trip like this.
My goal is not to get to the other side, but to enjoy everything inbetween, plus there is no time limit for me at this point in my life so that is what makes me think of adding a hobby like photography to the trip. SO many questions!! But I still have 4 months to answer them.
