Kodak K100 in 16mm Posted Monday at 03:52 PM The K100 has the longest running time on one wind I've seen on any camera. It's built like a tank and extremely reliable. BUT, if you don't have a reflex lens for it, focus and framing are done manually as in measuring the distance or doing your "best guess" which is ok for home movies but when you're spending $150 for three minutes of footage, you may want something a little more likely to be actually in focus. It was like the Cadillac of home movie cameras in the 50's but something like a Scoopic where you can actually see through the lens to focus & have a motor + decent autoexposure may be better for you. I know there's a big price difference but you've already spent that difference after 3-4 rolls of film/processing/transfer.
