I'm looking for Nikon to E-mount positive lock style adapter. I found P+S one but it doesn't have an aperture ring for Nikkor G lenses.
I have Novoflex and Metabones "standard" adapters but I can't use follow focus with them.
Have a look at allstar mounting system, they offer pl type locking for Nikon manual or auto lens on their custom made mount. I got one for my f3 and its professionally secure.
Thanks. It looks interesting but it's quite expensive. I would spend $320 for universal mount + $200 for E-mount base + $210 for each lens mount ( I have 6 primes ). Total $1780. Too much.
Ciecio7, a reputable adapter maker had recently started making EF lens adapter with PL locking mechanism, maybe worth contacting him to find out if he can custom make one? I had bought a lot of adapters from him through the year and he is great to deal with. http://www.ebay.co.uk/usr/ciecio7
Maybe someone wants to talk to the guy who made the Nikon Prolock for the F3 and Red cameras. Can't remember his name at the moment. He may in fact be working on it and more for the FS7 market. His Nikon Prolock for the F3 was about $900 but few who have it complained about the price given what it did and the alternative (buying expensive PL mount lenses).

The company is Optitek and the owners first name is Jacek.
