I just ordered a Canon 430 EX II (should be here any day now) to use on my 5D. I was considering the 580ex II but didn't think I would need all the power and features. Anyhow, I was wondering if the 430 II will be okay in high humidity environments (SE Asia).
As you guys might already know, the humidity there ranges from at least 60%-80/90% with the colder months being a little bit better. So will I be okay with the 430 EX II or should I return it and get a 580 EX II? Please keep your opinion objective for this particular situation only. Thank you!
