@boriscleto Thanks for your suggestion.
@jatrax I guess I'll go with the 18-135mm WR. Reviews sounds great and it would be a great carry around where I don't have to worry about it. Thanks for suggestions on Wide angle and Zoom lens.
@RioRico I do race photography and sometimes I have to stop shooting when it starts raining. I guess with WR, I don't have to worry about it. Thanks for your advice.
Weird but B&H increased the price of the 18-135mm WR back to its original price $529.95 (It was showing the revised price $459.95 until yesterday)
