I have a K-1000 and loved it during my student years. But I plan on returning this to my father (former photographer himself) and am looking to upgrade. As a Nikon guy, I prefer a camera that will work with the FX lenses that I have / continue to purchase and the batteries are a concern. I've looked into a list of cameras from Nikon and have settled on a N90s with the MB-10 grip (allowing me to use AAs). I have looked into the N80 but people elsewhere talk about the difficulty to find the correct batteries for it, though I never really looked into the type required or how hard they were to find. After some reading on here, most people that talk about their N90 / N90s talk about their preference to their F3 or F4. Help me decide, good folks of APUG!
