I am getting ready to make some lens purchases and am looking for some feedback before I make the jump. If you have either of these lens would you please let me know how you like them and if you would recommend them or another lens. Tamron 70-200mm f/2.8 Di LD (IF) Macro AF Lens for Nikon AF Tamron SP 10-24mm f/3.5-4.5 Di-II LD Aspherical (IF) Lens for Nikon Digital Cameras I'm also adding this: ExpoImaging ExpoDisc 77mm Neutral White Balance Filter for Digital Cameras. Thanks in advance for any advice!! BTW--I have a Nikon D80 with 18-135 kit lens.
