I've recently been experimenting with panoramic cameras after getting out a Widepan 617-A from my universities' stores (can't wait to try the TX-2 they have aswell at some point). Now, the problem I've been having is there seems to be an enormous lack of information when it comes to the WP617 models, the WP617-S in particular has caught my eye but I can't find anything on it, not even a general overview on the differences between all the models! I was wondering if some kind soul could point me in the right direction? It'd be much appreciated! Cheers, Ali.
