I’ve just found a picture of all the three screws : http://static.photo.net/attachments/bboard/00F/00F6Li-27906884.jpg

Hi Arran
lovely clear and easy-to-follow instructions. I have just adjusted my R3A (latest model) and it is looking good! I found that both the focus screw (1) and the vertical (3) affected the left/right adjustment. So after some playing around with all the screws, I adjusted this screw last. Nico (if you are still out there!): you will definitely see a difference with a 1/8 turn – your fine adjustments will be smaller than this.
My vertical (3) screw is quite loose, so I have tried to put a little nail varnish on the thread, but it is not easy.

Arran – thank you

Hi arran!!! I wanted to thank you for the detailed instructions on how to calibrate the rangefinder of the camera. They are definitely the best out there.

I managed to get the cover off. I wouldn’t have imagined the adjustment screws were so deep inside the body, though. The thing is, I wasn’t able to fix the infinity focus (it’s quite off), as the screw was so tight, and I’m worried about breaking something inside as i’ve read on many places that the whole mechanism should be handled delicately. I have a couple of questions. Do you remember which movement (clockwise, counterclockwise) moves the patch to the left or right? How much is it necessary to move the screw to actually see a difference? (1/4 of a turn, 1/8 of a turn, etc). What size screwdriver are you using to move the infinity focus screw?

I’m so frustrated with having a brand new camera with the rf patch off. And it was bought in the US (B&H) but I live in south america, so it’s a royal pain sending it back to get it fixed.

Thanks.

The original Bessa R looks at bit different. The screws are perpendicular to the length of the body as opposed to horizontal shown above. The middle screw is still the horizontal adjustment for infiniti.
