Working with Carl Zeiss Planar 1.7 / 50 T* C / Y ___________Motion Lapse Film

I only made this film about the Carl Zeiss Planar 1.7 / 50 T* C / Y mount, just to show how to disassemble the lens group and aperture system with the blades in. Before taking out the aperture system, remember to make some small marks so the aperture sit correct when assmble again. It can be a little difficult to the aperture assembly back in the plastic tube, so use a rubber stopper when assemble. There was a small spot with a kind of haze or so, in the inner lens group but those 2 lenses was cementet together so nothing to there...
