Newbie question: I have a D5000 with 18-105mm and 100-300mm lenses. I have just read that lenses have a 'sweet spot' where they give the best results, so I have two questions:
1/ Does anybody have any idea where the sweet spots are for those lenses, and
2/ When I use the 18-105 for lanscape panoramas, should I just automatically bring it back to 18mm or use it at, say, 35 or 50mm to reduce distortions?
So many questions, so little time.....
