Filter idea

Let say you want to use a specific filter on a shoot such as a Promist, and you either don't/can't have a mattebox or don't have time to change the filter every time you change a lens, I may have a solution. Since a lot of people are using adapters to adapt different lenses with a greater flange distance (Nikon, Canon, PL, etc...) there is a lot of room in these adapters for a small filter. I will run up to the local still camera shop and experiment in the next day or so to see if there is a way to do this. Another benefit would be lens flares. If you wanted a nice lens flare without a filter mucking it up you should theoretically be able to still achieve this if the filter is behind the lens like I'm proposing. People used to add filters and nets behind the lens all the time in the 2/3 chip world. I used to AC for a guy who used to put a nylon behind the lens and said it was his secret touch and for me to not tell anyone. I'll report back.
 
You told someone...

That idea works better with primes than with zooms. Bolex 16mm cameras had a filter slot behind the lens, for gel filters... We used to intentionally smudge 85s or Skylights for an effect... And the effect is very different from putting it in front - sometimes better, sometimes worse... Also cleanliness is next to Godliness whenever you put anything behind the lens...

Oh my, that brought back memories ... I was a lab assistant in the cinematography program at our local university in the late '70s, and we used to buy 85B gelatin filters by the box so the students could cut their own for those Bolex filter slides. They were an incredible hassle and the kids were constantly creasing them, putting big greasy fingerprints on them or cutting them so badly the edge of the filter would appear in the image ... or they just gave up and lived with blue footage when shooting outside. Not to mention that you could get light leaks and flare if you left the slide out altogether. It made me think the filter wheel on the first Sony and Ikegami video cameras I used was a gift from heaven.

I used to shoot BetaSP for 'America's Most Wanted'. The production department swore us to secrecy too, and would send us 'special' black nylon that could only come from Bergdorf Goodman in NY. I think Robert Stack was a bit kinky because I heard that he too, preferred to be shot with black nylon. Personally, I only used JC Penny nylons over my head when robbing banks.

Oops, I told also.

You know what's funny? The guy who I used to AC for who told me that used to shoot for America's Most Wanted :)
 
Ok back to the point, I played around with a 37mm threaded filter inside this Nikon G to Micro 4/3 adapter I own and it would be the perfect size if it was threaded, but it's not. I still need to experiment with more sizes, but it looks very promising.
 
Also this is also the case with my Ciecio7 PL adapter with a 37mm thread. These adapter makers should just thread it accordingly it wouldn't cost much more since it the perfect diameter already and would it probably be a selling point.
