@cOn. I would also recommend a all in one like an 18-105 or a 18-200. I personally have a Nikon D5100 and use a 18-200 from Tamron. Incidentally when I bought the stuff a couple of years back it cost me 50K
It i very difficult in general and also heavy to carry multiple lenses. Add to that a tripod and you can feel the load. I did that for a recent trip to Cambodia and I could feel the pain. Also switching lenses is not easy. Once you graduate to more serious stuff or feel like splurging more go for the primes and the more expensive lenses. I am not very clear about a 50 mm prime though but maybe it is just me.
A 2-3 Lens kit won't be that heavy, just requires a proper bag. A tripod is a different story.
Switching lenses is very easy infact ..
