However, there were indeed a lot of gripes about why the EF couldnt be made to take an FD mount. It would certainly have saved me a lot of money, i still have a box of FD mount lenses and A1 bodies that havent been touched for years.I do take the point about batteries though, i feel they have missed a trick by not maintaining battery type by series, e.g. all the same in xxxD, and different but equal in xxD. But having said that, rechargeable batteries suffer from memory depreciation, and it may be just as well for manufacturers to have a new type, to prevent old batteries causing internal problems. It could be worse, it could be Nikon, with all the problems they have had with their batteries causing allsorts of faults within their cameras.</blockquote>
