Alright so I have shot a few weddings and with my Christmas $$$ I would like to add to my wedding equipment. Please let me know what you guys recommend! Thus far I have a Canon 7d, 24-70, 50 1.8, 55-250, 580 exii flash, tripod, umbrella, 8 and 16 GB sandisk cards, and small filter for flash. What do you recommend as my next buy? I'm guessing another flash is needed but if so what one do you recommend? I use natural light when I can but my concern is for church weddings without much light or just church weddings in general. The unfortunate part is I can only spend about $200-$400. As much as I would love to have a second camera body I can't afford that right now and I just borrow my sister's rebel as a backup.
Thanks a lot!
