Checking of the calibration of my R3a
I just calibrate this morning my rangefinder on my bessa R3a. I followed the well known article of Arran Salerno .
To be sure of what i have done, i calibrated the infinity focus on the moon.
Now, i just check the close focus and:
- scale focus is at one meter on my lens
- i have one meter from the point that i focus up to the front of the body's camera (where it's written R3a)
- and so, i have approximately 103cm up to the film mark
My worries are i was thinking that the scale focus will give me the exact distance between the subject and the film because, when we focus, we focus on the film.
If you could drive me, perhaps i am wrong somewhere.
Thanks in advance
