I have recently purchased this lens and I'm loving it. Recently when I took a macro shot I realised that bokeh was dirty so I opened up the lens to clean the elements. I must have rotated one or more of the elements cause now the lens is not functioning properly. If anyone with a copy of the lens could document the element layout I would really appreciate it. I have tried a fair amount of combinations but can't seem to get it right.
