I am a zoom guy. My travel kit is two bodies, one with the 14-140mm MkII, and the other with either my 9-18mm or my 100-300mm. I used to carry some primes but sold them all because I never used them. So ... my question is: These two countries and Bhuddism in general are new to me. Do I need a bright prime to shoot inside the stupas and temples? Monasteries? Typically on trips I have used my 9-18mm on my monopod and been happy with the results. Can someone who has been there, done that, offer some advice? i am sort of eyeing that new 7.5mm f2 that has come out.
