1. Undecided as to which lens to buy and need all of your advice! Intended to use it on Canon 7D body. Should I buy Tamron 18-200mm PZD f3.5-6.3 DIII VC PZD, priced at $963 vs Canon EF-S 18-200mm IS f3.5-5.6, priced at $1070. Thanks!!
2. Should I buy one of those lens or should I go for EF-S 15-85mm f3.5-5.6 IS USM at $1125 + EF 70-200mm F4L USM $999.
