So I'm leaving for London at the end of next month for my honeymoon. My current set up is in my sig. I was planning on taking the T3i, kit lens and maybe the 40mm pancake (just for IQ). I would really like the option of having the RAW files and familiarity of my camera but I just have a feeling that walking around England for 8 days with the T3i is going to be cumbersome. My other option is to borrow a Nikon CoolPix L830 from a family member. This would would probably be easier to carry around for extended periods. For all your frequent travelers out there what is usually the best option?
Also, I've been reading a lot about hassle from customs coming back INTO the country with regard to electronic devices (cameras, iPads, etc). Is it recommended to fill out one of those forms declaring that my electronics were in my possession before I left the states? Or are these just horror stories and it's usually not a big deal?
