This September, I'm purchasing a one-way plane ticket and embarking on a journey around the world. I really want to purchase a decent camera for this season in life, as there will be plenty of opportunities and exciting things to capture. I've been talking to a few people about what specific camera I should purchase for this trip. Though these recommendations have been all over the map, the two most common suggestions are for me to purchase a Nikon D40 or a Panasonic Lumix GF1. Honestly, I'm not quite sure which camera will be the best for all-around photography as I travel. I've used both cameras to a degree, but not extensively, and I've never been enough of a photography nut to make an educated decision on which would be best. Between the two cameras, the size and weight does not matter to me. I would be comfortable with either camera as each are fairly compact and lightweight. What suggestions and thoughts do you guys have?
