With peel-apart dissapearing, I've been meaning to get an SX-70/680/690 and get into integral film. Perhaps now is the time... Pity they no longer make monochrome 600-series film though either.
Me thinks I'll be getting the soldering iron out on an SX-70 though, and doing one of the many timing circuit mods. The ND over the lens certainly does not appeal, though this mod or the Blend filter option might also fly. Thanks! Skj.
