Thanks for all the input I really appreciate it!
I noted that IS is weather sealed which may be very relevant especially in very humid areas. (amazon etc)
Weight and size is something I also need to consider.
I currently want to take
Canon 60D (purchasing from Panamoz)
Canon 24-105mm F4
Canon 50mm F1.8
I'm thinking I might need some extra length for maybe wildlife etc but I also don't want to be lugging around too much equipment . I'm drawn to the 70-200mm IS because of the reviews and fantastic examples I've seen in a pic example thread. But how much I will need IS I'm unsure hence why I considering the non-IS - I also save around 400 which could be spent on a decent bag , polorising filters, spare batteries.
I did also consider taking maybe a cheaper 55-250mm - I'd be less upset if I has this taken from me, lighter, smaller, less 'look at me'
Or Ive even considered another prime - 85mm F1.8, 135 F2 for example ....
Thanks for that very helpful.
Wow.. Sounds exciting, sorry about digressing, is this trip for photography purpose? What are the places u plan to visit? Just curious, if one were to plan a trip to south america for about a month or so, what is the budget one needs to have? Been thinking of something like this for sometime now.
Its not just about photography . Photography is hobby of mine and I'm still very much learning but I really couldn't visit south America without my DSLR. It's more about the experience travelling brings.
In 2011 I spent a year traveling visiting Fiji, New Zealand, OZ, Indonesia, Thailand, Laos , Vietnam , Cambodia , Malaysia , Borneo, Phillipines etc It was hands down THE best thing i ever did - a few nice photos along the way was just a bonus. I've just caught the travelling bug so I've saved up this year again and I'm off for the second time.
I'm going to Brazil, Argentina, Paraguay, Bolivia, Peru, Equador and then flying to Costa Rica to see abit of Central America before a flight back to Thailand (just because I love it

)
Ps - id rather not discuss costs on here but it is not cheap trust me once you factor in flights, travel insurance , living/spending. I'll be taking a backpacker route though using local transport , cheap hostels so it keeps the costs reasonable. Im also an adrenaline junkie so throwing myself out of planes alomg the way tends to get expensive lol
