I don't want to get in a big debate, but merely point out that many of the "quality control" issues concerning Efke, are actually attributable to improper handling during processing. Efke films have an exceptionally soft emulsion when wet, and are easily damaged and abraded by less than careful handling, sediment abrasion, etc. I'm not saying they have never had a bad batch, just that in my experience with the film, most of my "issues" turned out to be happening on my end of things. Once I began to understand the special nature of this film, they cleared up.
