I would like to leave my lens fully open all the time without having to find an aperture converter. But other than bluetac I cannot find anything that would attach to my Nikon lens and leave it continually open.
I have a Chronos 2.1-HD High Speed Camera with MFT mount, and I will only ever need to use this lens fully open.
I plan to buy a focal reducer, but looking for a Nikon to MFT mount, none have aperture controls on them. As I will always been needing the F-stop in its lowest position, I thought/hoped there might be a situation where I could find a way to leave the F-stop "open".
