Nikon Mount on BM4k URSA PL

Why?


I have a comprehensive set of fast AIS Nikons, which I can't hope to replace cost-wise. Time to get started and draw the proper design and devise the method for least waste of metal stock. The little guys in Dongguan could probably dream about it the night before, design it, make it, hard-chrome finish it and package it before I can and sell it for less than the cost of the metal stock too. - So onward to hunching over the machine and looking like Quasimodo by the end of it all.

There is probably the "doing it because I can, not necessarily because I should" factor at play here as well.

Sort of how it will look. The flowcast machined bronze adaptor piece will have the Nikon F-Mount attached to it as it would be to a Nikon camera and the adaptor piece attached to the intermediate BM adaptor piece for the PL-Mount in place of the PL-Mount.

Failed upload will try again. No good again will try later.

Re: Nikon Mount on BM4k URSA PL

It looks like image upload is permanently impossible with my current computer. It has some idiosyncracies.

Here is a link to some test footage with the Nikons on the BM URSA 4K PL with custom mount.

It was shot in "film" setting which requires colour grading afterwards. The images have not been graded. I deliberately shot in an hostile late afternoon overcast environment against the sun to drive any defects to the surface. So far the results have been encouraging. Professional cine lenses would be better but the Nikons will do in the meantime.
