How often do you hear "get the right tool for the right job". Also, Canon L lenses hold their values better than 3rd party lenses.
Asking what the right tool is what this thread is about - and "right" doesn't mean "most expensive", not even in an enthusiast's forum. For me, the re-sale value is only of concern for lenses I might actually want to sell again, but if I get the 24-70ii I'll keep it and the money is gone for good.
I had recommended the 24-70 I and 70-200 F/2.8 IS II to my boyfriend as the preferred zoom kit, but they were out of budget.
For me "budget" is relative to what a business is about: Earning money after some sane period of time rather than spending it. I *could* get a 5d3, 24-70ii and a 70-200/2.8ii, but I'd be near broke then and I serious doubt that would be smart business in relation to my first clients' expectations and my first salaries.
I had recommended It's going well - the brides are thrilled with their photos and are actively referring me to other brides :-)
Congrats to your successful business start! Please don't move to Berlin/Germany, will you :-> ... I guess being a women does help in this business since it's not that common, allows you more freedom and maybe people tend to be more relaxed? Well, can't change this fact now for me and have to work with what I am :-p
