Hello. I'm getting into a nice S16 Bolex EBM, and leaning into a bunch of potential lens options. Trying to make the wisest decision for a good set of basic primes or possibly a good zoom paired with one wide angle prime to get very wide when needed. I have a bayonet to c-mount adapter and a bayonet to M42 adapter (I have a lot of decent stills lenses in M42)...but...
I'm hitting a wall on two really concerning issues, no matter how much I ask around or research it --
1) Issues about focal flange distance are concerning to me, especially with the possible use of adapters, given the Bolex's notoriously weird "compensations" made with the Kern Switar lenses. I know the Kern Switar H16 RX were designed to compensate for some kind of "odd" focal flange distance (is that right?) and prism compensation on the bolex EBM viewfinder. The prism compensation doesn't bother me because I can just open up a third of a stop to do that myself, but the focal flange from back element of lens to film/sensor plane is very troubling. I guess I just am worried that anything "other than Kern Switars" will be out of lens tolerance or something, and they may produce a slightly blurred or affected image, especially with adapters that may be a bit janky. Is this true? False? Halfway true false true? And does that mean if I slap some M42 mount lenses or newer glass on it via adapter, that it'll give me a blurrier image? I'm really concerned that I'm going to be playing with fire by disregarding the Bolex specs/design tolerance by using new glass (say the Sigma 10-20 zoom, 18-35 zoom, or Rokinon primes, or even any of my olde pentax M42 lenses to be honest).
2) The other issue is the whole MFT sensor lenses on S16 camera issue. In terms of coverage. The thing that cracks me up is there are TONS of articles and posts online about using S16 glass on MFT sensor cameras, but almost NOTHING the other way 'round. I guess I'm one of the few guys with a S16 set-up who really want to put some new Sigma or Rokinon lenses on it cheaply. I kind of want to do the same thing people are doing with BMPCC, except using FILM stock instead of digits (beep boop).
So far I'm looking at some combo of these lenses:
Camera: BOLEX EBM S16
Lens package option #1:
Sigma 10-30 zoom (or) Sigma 18-35 zoom
Lens package #2
Rokinon 14mm prime
Rokinon 35mm prime
Lens package #3
Kern Switar 10mm
Kern vario Switar 16-100
What I have now lens wise is from my K3 set-up as follows:
Pentax SMC 50mm
Carl Zeiss Jena Sonnar 135mm
Meteor zoom 17-69
I guess I'm saying...."what's gonna be blurry....what's gonna be crappy....what's gonna be good...and what's gonna not be good on a BOLEX EBM S16??"
