I have been doing some research on traveling gear necessary for keeping in touch during trips, in particular, cameras, cell phone, and laptops.
Let’s start off
Let me start off with saying i am a big fan of Digital SLR cameras. I know many people who are traveling would say that they are bulky, takes up space, and cumbersome to navigate through the 100s of options. I agree mostly, but for the quality of getting good solid professional pictures that is worth the effort and space.
But, given the choices we have it is often excruciatingly painful to make a decision. It is not that we do not have knowledge on what features and tools that should be present in a camera, far from it we are stymied by AP, because of something called Paradox of Choice.
Nevertheless, we still have to make a decision. So what are the factors that I look for – a good range of ISO numbers, a good fast lens (the lower the F number) – this will ensure that those portraits of people from exotic places are sharp and beautiful with good depth of field, and a good zoom (for those distant shots of places you would not be able to walk to). Lenses are very imp: a good lens makes or breaks a picture, for example Nikon AF-S Nikkor 35mm 1:1.8G is one of the best and cheapest lenses produced by Nikon, and it weighs a mere 7 Oz ( 200 gms)
2) Cell phone
Again, too many choices, but i can say one thing. If you want to travel internationally and swap SD cards (from US cellphone carrier to local carrier) first talk to your service provider in the USA to unlock your phone, and next get a quad band GSM phone. It will save you a lot of money
3) Lap tops
Main consideration is that it should be portable (should be less than 5 Lbs) , have good screen resolution (screen size not greater than 13-14 inches), and have a lots of storage capability (250 GB +), SD card (very imp for quick transfer of photos or you can get an Eye-fi card – Wi-Fi SD card ) and WiFi capability (other that western Europe, and developed Asian countries most have sporadic WiFi)
You might have noticed i did not specifically recommend anything – I leave that to your own judgement.
