LUVMYDOGS: Unless you are not expecting to go for traditional b&w, processing and developing yourself, and if you are completely happy with the digital then, by all means, sell the F5 and associated ancillaries. You will need the cash for updates, back-up storage devices, and a new camera when your digital a.) fails after the warrantee expires (you won't be able to get it fixed), or b.) you need to purchase the newest, up-to-date model.
