I've planned to rent a 17-40mm f/4L for this shoot cos i think i'll need that 'wideness' for table shoots. I myself have a tamron 28-300mm f/3.5-6.3 but somehow i feel that 28mm's not wide enough. I do not have a bounce card, only an omnibounce, or maybe i've to make my own bounce card.
Quite excited cos it's my 1st time doing a wedding shoot that's why i need some opinions on what to do. I know what u meant by the frame counter thing, fortunately my EOS 30 have a custom function to rewind film with the film leader out.
