Tamron 70-300mm, Sigma 70-300mm DL or Sigma 70-300mm APO.
And so the questions that come with it:
- Sigma's APO was an upgrade from the DL but is it really a must-have?
- Why is the Sigma 70-200mm more expensive than a Sigma 70-300mm?
- Are the lenses compatible with my D40, in the sense that 3D matrix metering, autofocus, exposure meter and electronic range finder will still work? Because it says "(Nikon F)" and my current lens is a G.
Any other information would be really nice :)
