yeah man, you should. I always go out with two primes, the 15 and 55. >
2 primes sound do-able for lens swapping... but don't you find it restrictive in terms of flexibility? this is what i wonder most about people who use primes mostly... can they switch lenses fast enough and not miss the opportunity?
On a predictable situation, like a gathering of people in a limited space room or when you know what shots you are after, its fine. But what if you are on a walkabout (which current TS is asking about)? have you guys who use primes been able to capture most shots you wanted or lost many bec time was spent changing lenses?
