    that's a matter of choice:
    would you rather be locked up in a "safe" Apple jail(i.e. ecosystem) or roaming free with Google's eyes on you at all times ?

    Thank you Bjorn for your kind words.
    If anyone here cares this is my opinion based on selling (high end electronic movie camera) adapters for 12 years:
    1.Adapters should be set up with close...
  3. OK i found another way: All still camera lenses...

    OK i found another way:
    All still camera lenses are setup short from the factory- i.e the back focus is incorrect. The bodies are also short- i.e. the flange is incorrect. Since the are both short...
  4. Colimation to the sensor plane has very little,...

    Colimation to the sensor plane has very little, if anything at all to do with the lens performance. Any collimation error is easily corrected using the focusing ring on the lens. Typical machining...

    Haha politics are definitely your forte. Lets see the examples. And no- defocused images will not cut it
  6. Focusing is something easily achieved with a part...

    Focusing is something easily achieved with a part of the lens called the focus ring. I'm surprised I needed to explain it here. And no- it is not optical performance. It's is a mechanical adjustment.
  7. I think we need to clear up one thing- the...

    I think we need to clear up one thing- the typical back focus error has zero effect on a spherical lens optical performance, i.e. resolving power, contrast, field curvature, lateral dispersion,...
  8. What's a warped film plane have to do with lens...

    What's a warped film plane have to do with lens back focus? First flatten the film plane. Back focus change on the lens is not going to fix it.
  9. I'm not sure I understand. This is simple...

    I'm not sure I understand. This is simple physics: As the object moves closer to the lens the image behind the lens moves further. Therefore the nodal point of the lens has to move further from the...
  10. Prime lenses usually do not get softer when the...

    Prime lenses usually do not get softer when the back focus is off. Same goes for the camera flange. The main issue is that if they are "long" (image forms in front of the sensor ) you will never...

    Anodized to protect the metal and powder coated on top of anodize to make uniform finish and for the color aesthetics.

    Many factors influence actual tolerance. With film the specs were easier to determine as the recording medium was the same, no matter what format, size. With electronic sensor you look and format...
  14. Theoretically yes but with the grain on the film...

    Theoretically yes but with the grain on the film the same size as 35mm essentially limiting the resolution, the deeper field as well it did not require different tolerances. Maybe with an 8k sensor...

    Ah I see- you mean the FL/speed of the lenses. Yes maybe but we never really adjusted them to tighter tolerances than 35mm...

    Not only that- it now puts the camera flange and lens back focus into the "unknown' realm. I've seen ACs go so lost so quickly.... going nuts adjusting back focus with every lens change...not a good...

    Maybe he can talk to Guy Ritchie- the characters from his films would be perfect ;-)

    Shitstorm?
    Back in the day this would be a casual conversation. Oh well...got to get with the times...

    Not sure if chasing tornados is exactly a controlled environment haha

    While this is worth noting it needs proper context. It obviously has not worked out and neither has the back focus adjustment on the Fuji zooms. The Digi primes were made at the very early stages of...

    How do you know if they have 1, 2, 3 thousands and which direction? It is completely random. Making a single shim and marking it "R" makes no sense...
  22. this way the camera/lens relation is not...

    this way the camera/lens relation is not maintained. Native rf lenses will not work with that Komodo body- at least not correctly. Wouldn't it be a better solution to correct what is actually wrong?...

    I'm just saying how it should be handled to keep the lens/camera interchangeability real.

    I definitely see value in a properly calibrated adapter.
    IMO here is the order of adjustments if there is an error
    1. Camera base mount- if the RF mount is off the nominal 20mm with a tight...
