I have just received quite a nice Bronica EC with Zeiss 80 2.8. All nice & clean & functioning but the aperture is a little sticky. Anyone been inside one of these? Looks quite straightforward, front & rear elements off & a flood clean . Lovely Camera. All functioning well, Seals to replace, apart from that pretty good. Got a box full of the Rubber lens hoods & Caps of Varying sizes to get rid of if anyone is interested? Varying sizes.
