Okay THANKS !
Well now I was very worry about my cam and I asked my Professor (I am studying Engineering-Sciences in an University) and he gave me his own calliper -> 1. it`s digital; 2. it has an almost zero tollerance!
Now its exactly 28.8 mm
And I am glad about it ! THANKS !
Well - about the rangefinder :
if it`s like You told me, then it isn`t really important, if the mark for 2 m shows exactly at 2 m , because You have the tollerances marked on the objective (16 11 8 5,6 4 3 3 4 5,6 8 11 16)
Thank You again ! Soon, I will post my photos and describe the way I used it !

That's great to hear the camera offers you a number of ways to ensure correct focusing that allows you to use it in a number of ways. it's good to know how it all worksand now you have the know how you are able to put them all to good use
Looking forward to seeing your images!

Given that a lot of current auto-focus lenses have no depth-of-field scales, it figures that eventually someone would come along who has never seen one. Is that what they call progress???

I'm afraid so (sigh). And try telling them that often a step forward means a couple back. I mean the poor things use calculators and computers to work out DoF and the hyperfocal distances...

I realise that the tools being mentioned are very accurate but can't see the point of measuring beyond the point you can adjust to; so measure to a millionth of an inch by all means but you'll have to adjust the camera to a millionth of an inch to justify the cost of the tools, imo.
So why not something simple, like this? About a fiver in my local market...
You'll need to measure the depth from the top of the ruler and also the width of the rule and take one from the other, but that shouldn't be too hard. Best to take several measurements and work on an average.

That has always been my way. First I play with a new cam and check if it sounds right, then I burn a roll. Within some hours I know if it has to be repaired. Keep it super simple!
