hi im new to this forum, found the link from serious compacts.I have sold my gf1 and lenses to go with it as i want to get an lx5 or dlux 5 ,something more portable,(maybe x10) will have to see some images first. anyway i know i also need a dslr for other types of shooting and was going to go back (shock horror) to nikon or canon only to realize there is no adapters for zeiss contax rf for either dslr, as i want to keep the lenses ( also have pentax pk) i started to look at sony nex. can these lenses go on a sony nex??? i hope so because i really dont want to sell the lenses, had them on the gf1 and they were superb. also if they go on is the focal length doubled like gf1? also are the adapted lenses top heavy on such a narrow body? have seen images from sony nex and i am very impressed!!
