    It seems a bit contradictory. Blockchain was supposed to add legitimacy to the crypto but also allows to track it by the authorities. How can something be secretive but a the same time transparent to...

    I thought the appeal of crypto was a monetary system outside of the traditional banking system, which made it immune to the pitfalls. since that was all a lie since the banks and now the government...

    double the number of teeth on the follow focus gear will half the amount of rotation of the knob

    Of course anamorphic lenses are different and need proper back focus and flange. I've said it about 5 times in this thread.

    number of teeth is determined by the pitch and diameter. Just looks for the most teeth - that will be the largest gear

    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:

  17. 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...

    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

    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.

    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,...

    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.
  23. 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...

    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...
