    All im saying is that for a large format camera the tolerances is far bigger than for lets say a super 8 camera. The tolerances scale with the sensor. If you want to achive the same fov image with...

    The reason for digiprimes being user adjustable is
    1. they came out when mounts for 16mm digital cameras where all over the place.
    2. When shoothing 16mm / smaller sensor you naturally use a range...
  3. No as if you want the same FOV for both cameras...

    No as if you want the same FOV for both cameras then the 16mm camera has almost half the nodal to back plane distance. Which gives it half the tolerance span when you colimate it. Basically a smaller...

    Basically you use a wider lens for the same fov on 16mm and the wider the lens the more crucual is the tolerance for backfocus to no offset the marks, no?

    A 16mm camera needs much tighter tolerances for backfocus then 35mm camera. Like twice. As the distance between the lens nodal point and sensor plane is shorter.

    To tie back to that other thread. Do you offset backfocus when going between infrared and visable light or is that done in the filter?

    I don't know if the RF mount on the Komodo has removable chims if it's to far out or what chims to use to bring it further out. But of course yes it should be checked and corrected. But I doubt RF...

    I discussed this with the guys at Kippertie. Apparently the four holes on the side are not perfectly machined and bolting it that way makes it difficult to shim that mounting point. That is why the...

    Yes, happy A was hte case or there would just be chaos with bachfocus issues.

    Now, why did Jarred and gang not atleast give Komodo a flat machined front around the FD mount with 4 threaded...

    Yes but if the glas inside of a specific csmera takes the distance between the flange and that glas and multiply it with a factor then that would mean that every lens adapter has to be colimated not...

    Someone that knows more about light transmision trough glas please chim in here and correct me if I’m wrong. I assume that the flat filter glas behind lens work as a factor to the flange distance....

    The spec distance for pl flange distance is 52mm optically speaking. So yes the physical distance may stray from that as there is all kinds of glas elements between the flange and the actual sensor...

    What graham does not understand is that a slight offset in backfocus does not change a thing except that your focal lenght change extremly slightly. And your focus scale get an offset. You really...

    My last try. As no camera is the same... you need to check back focus when you add Grahams adapter into your setup just as you need to do for any other adapter as the chances are more likely that...
