Well, I'm still debating on the kit I need to buy to allow me to take high quality panos and another question has come up that I can't find an answer to. Hopefully it's not too basic a question!

Does the focal length of the lens really matter? I've always used a wide angle for landscape as I wanted to get as much in the shot as possible and obviously a 17mm focal length will get more of the scene than a 70mm. However with panoramas doesn't that become irrelevant. If this is the case, would using my 50mm prime (the Canon f/1. be as good as (or better than) heavy glass such as a Canon 24-105 or lower quality glass such as the Sigma 18-200?

What am I missing?
