Dioptry questions

[-Benjamin-]

Hi all,

I'd like to know if there is any reason why my dioptry settings should be different when I change the lenses on my camera. Or is dioptry set once for all, no matter what lens you put on ?

Also, I often move the dioptry ring by accident when I manipulate the camera, like getting it out of the bag... And if I have a short prime like a 10mm on the cam, I'm not sure how to operate to reset dioptry (with the split image). I mean unlike with the long end of a zoom, I can't see far objects. So should I use any vertical object that is in a reasonable distance (i.e more than a meter away) ?

Thank you in advance for any input or easier advice.

PS : I hope my questions are clear. Please correct my English if necessary... :?

What sort of camera?

[-Benjamin-]

Leicina Special.

I didn't think the camera model was important. Could it also have an influence on the answers ?

Thanks

I believe the word is "diopter" (not dioptry).

I'm pretty sure this is the case; the diopter should be set the same for all lenses.

Also, I often move the dioptry ring by accident when I manipulate the camera, like getting it out of the bag...

Focus the etched split image "circle"; certainly it has to be in focus, no matter what lens is on the camera, for the VF system to work. Often it will have some small imperfection[s] in the etching, making it easier to focus on.

HTH,

Ok.

Mitch and Rick, thanks to both of you.

It's cool to have people here who help me improve my knowledge in filming and in English...
