I went out late last night to take photos with a lens my friend lent me for two days. I'm trying to decide which lens to buy. I have a little extra money I can use and it's very, very difficult to decide what to do, I think you could say it's a luxury problem but believe me I've worked very hard for that extra I've got!   This one is shot with my friend's lens Canon 24-105 f/4, I don't think that's what I want. Should I keep the money and save more so I can buy the Canon 24-70 f/2,8 L II USM?  Hmmm?
