just a short question. I will be in Madrid the next view days. I want to visit the Barajas-Spot, due to some descriptions on the internet I think i will easily find it (I will take the metro): exit to the left, walk in direction tunnel, ...
But I do have 2 questions where I could not find an answer:
1) At what times can it be used (to avoid backlight)?
2.) What kind of zoom lense do I need for the spot? From what I saw the airplanes are pretty close, so would a 18-135mm lense be sufficient??
Due to luggage restricitons (no I am not flying Ryanair, but I have some more stuff to carry) I don't want to take more than one objective with me.
thanks a lot for your help
