Originally posted by snpsht Based on the advice given, I have ordered a flash (AF540FGZ 2) and will spend at least an hour a day between now and the wedding (three weeks), using it with the lenses and working it out. Hopefully by then I'll at least have some idea of what I am doing!
It looks like the 20-40, the 35 and the 50 will be the most used lenses, but I'll take along the 12-24 and the 90 just in case.
I haven't read all replies and following might have been said by others: do not forget to enjoy your daughters wedding! At the end of the day, I think she'd appreciate your company more than you being "away" because of photos.
With that said, if I were to cover a wedding using the lenses you have, I'd go with following:
20-40, 335 and 50mm
12-24mm: I use such focals for establishing shots, such us the location of the wedding and stuff like that. I often end up with 2-3 photos at such focals unless the wedding took place at some very nice place, in which case I may end u with 4-6 pics :P
That's of cause just me. The super-wide focal is nice to have, but I can manage just fine without it.
20-40mm: This would be my main workhorse to use for especially candid and group photos.
35mm Macro: This is my rings and bouquet lens (and maybe decorations sometimes). I rarely use it for other stuff.
50mm: This would be my second most used lens, for stuff like moody shots, portraits and also close-shots of the rings, bouquet and decorations.
I find that the focusing can be a bit off - take plenty of pics with this one.
90mm: I own it but have never used it for weddings, however with just the gear you have, I'd use this for formal pics of the couple, if you will be doing such a thing. If not, then I'd leave it at home.
Flash: great thing you are going to rent a flash. I mostly use it from the bridal dance and onward. If you are going to use it as fill light, for instance outdoors, then practice using humans, not just some random stuff. It makes all the difference.
