  1. Thanks Mark, I did just what you suggested, I think. I put the 1500 on a tripod and put a flat focus target 8 feet from the film plane. I then set the focus of the lens to 8 feet. It seemed dead-on. The focus ring does not move at all when zooming out, and it appears the rest of the field of view stays in focus, so I think that worked. I will do the same test on the 650 tonight. I appreciate your help! Greg Lytle
  2. Hi folks, I own a Porst 650 XL and Porst 1500 XL Microcomputer and was wondering about the the precision of the split viewfinders on each of them. I read the instructions which instruct me to zoom in all the was, focus zoomed in, the zoom out to a desired wider angle. When I zoom in to focus, the split finder lines up, but the split finder lines do not stay aligned upon zooming out and I guess I thought the lens should be parafocal upon zooming. Does this mean my split viewfinder is not accurate? Any guidance is appreciated. Thanks, Greg Lytle
