I have been asked by a SI2K owner to obtain a quote from a local precision engineer and machinist to reproduce a copy of a speedbooster mod I made about three years ago for my SI2K. If he is willing and able, I shall post contact details for folk who might want to have their Speedbooster parts made, to contact him direct. He does stuff in CAD these days so the machine drawings are kept in computer files. Owners would need to supply their own BMPCC Speedbooster for the necessary machine work to be done on it and the IMS-Mount to be made and fitted. The mod does not prevent the original m4/3 mount from being refitted. In this clip shot on the SI2K with the BMPCC Speedbooster, ND and IR filters were used. The lenses were Voigtlander 40mm f2 and Nikon 85mm f1.4.
