Thank you very much, you confirmed some of my initial thougs and explained better some other concepts.
The point is that gear helps (also a lot), but i think i can make my own "way" using feets and practice.
Probably i won't buy nothing "only for the wedding" - the flash & the fisheye were already in my thoughts and the second body too (my 60D is working hard in those years )! But we are talking about 200$ (180 € in fact) for Fisheye, 100$ for flash (found some cheaper but good version of 430 EX II) and an eventual IInd body, and i got a year to work this off
Thank you again
