So I'm currently looking at two options for the FX/DX kit. I'm keeping both until a 24mp sensor is under 2k, but for now I need to keep both options! Here's what I'm looking at: Option 1: 17-35 AFS (don't own) and 24-120 VR (own) Pros: 17-35 gives me a 2.8 wide angle zoom on FX and a wide to standard on DX. 17-35 will see more use on DX due to work needs. Cons: No 2.8 coverage from 35 to 70 (have a 70-200 VR) Option 2: Tamron 17-35 (don't own) and 28-70 (don't own) Pros: Tamron is cheap and sharp for price, will not break bank on the wide end. Will have 2.8 coverage from 28 to 70. Cons: Tamron is a non AFS lens that will potentially have more use in DX. 28-70 will see less work due to crop factor, but will allow me to have standard 2.8 up to 70. Tamron is not constant 2.8 on wide end. Different opinions welcome. Leaning towards option 1, but the chance to own the 28-70 is tempting. I've never owned that fine lens! Can't afford 14-24/24-70 so don't mention it!
