Just wondering... Have anyone here had their friends wanting to borrow your lens... Especially the expensive ones? I have a friend and a colleague always asking me if they can borrow certain lens. Just today, the colleague, upon hearing that I just purchased a certain lens, immediately asked if he can borrow to shoot for our company's function next week. I will not be shooting as I am put in charge of other things that day. How do you reject them without making them feel offended? I can't say that I need it since I am going to be there as well.
