Hi All, This is of course a highly speculative thought, but if I am lucky enough to make it for another 30 years and am still able to use a camera, which of those available now would most likely still be fully functional? Right now I mostly use a Canon T90 and Elan 7n but I have a variety of other brands and models as well. I am a light user, shooting approximately 30 rolls a year, but enjoy the process of shooting and developing my own film ( since 1966) so much that I well may do it as long as I live. The specific issues I wonder about are deterioration of the camera through aging alone ( I have seen shutters and LCD displays die on little used cameras) and battery availability. I am sure there a number of other issues that could be problematical, but these are two that come immediately to mind. I do want built in autoexposure and autofocus even though I currently can use manual focusing adequately well. I am confident some sort of B&W 35MM film will be available three decades from now, but I wonder how many cameras (other than fully mechanical ones that have been vacuum sealed for longevity) there will be around that will be able to use it. I look foward to your ideas on this, Jay L.
