To the OP:
Find a pro camera store, a good one.
A good sales person knows what they are talking about, and wants to solve your problem. They want you to come back. With cameras, once a good store has earned your trust you will be back - and back - and back with your money to buy all the accessories you "need". Cameras are like that, they need constant feeding. A good camera store knows that.
The store I like in Vancouver used to let you "rent" you the lenses you are interested in so that
you could determine whether they suited your needs or not. (I haven't lived in Vancouver for a number of years, so I don't know if they still do this so I won't name them - but it was common in Vancouver). If and when you bought a lense the "rental" was credited to the purchase price so if you actually purchased it didn't cost you anything extra.
Good camera stores, judging by posts I read, are few and far between - but once you find one they are treasures. You won't get the best prices from them, but you will save money in the long run by not buying inappropriate equipment. Actually you won't save money... we photographers know that equipment purchases expand to fill any available cash.
Good luck - find a better store.
