Simon: 1. Please keep us (me) updated on any response / recommendations you get from Polaroid or Silverfast in regards to the focusing issue. I've noticed decreased sharpness in the middle of the film (35mm) with increased sharpness near the edges--I assume this is so because the film is closer to the film holder at the edges. But looking at the final prints--excellent sharpness and thus pragmatically it's not that huge of an issue since I use 35mm. Thanks.
