"it is not possible to Focus my 65mm Rodenstock to infinity"

I am missing something obvious here. I also have and use a Chamonix 45N-2. My 65mm f/4 Nikkor-SW has no problem focusing at infinity with its OEM "regular" bellows. Are you screwing the front standard into the female threads nearest to the GG?

Hello and thanks for your response. Of course the front standard is mounted into the last/shortest position possible. I attached some photos to see what I mean... in every position the distance between lensboard an ground glass does not reach nearly something with 65 mm.
Shortest distance seems to be 75 mm...

80 mm is possible, but no, absolute no movements at all....

If anybody can help, please let me know.

Thank you, Ulrich

Possibly try moving the 2 horizontal knobs in the bed forward to allow the camera to close more? We have the exact same camera and as you can see mine easily accommodates the 65mm lens.

If you release the two knobs for the rear standard swing, you'd be able to gain another couple of centimeter which should allows you to focus your 65mm lens at infinity, albeit I would looked at the 45H models if your wide angle lens is so wide.

Is there a separate knob that release the bed to move? My 45H-1 has one.

Thanks a lot Greg and Roberto,
you are right, I loosent just the 2 knobs for the rear swing on the top of the dropbed and that was shown on one of my photos... BUT there is another fixing knob on the bottom of the dropbed which can be unlocked, so the complete knob is moveable and does not get into the way of the bottom of the rear standard.
Now I have "endless" way to focus....

My error - and just so easy to solve - thanks a lot for opening my eyes....!

Best regards

Years ago when I got my 11x14 Chamonix, I put my 5.9" No. 5 Gray Periscope lens on it and was surprised that I couldn't get the lens to focus at infinity. Actually fabricated an adapter so that I could achieve infinity focus with the lens. After using the camera in the field a few times, I accidentally discovered that by loosening the knobs and moving them I could easily achieve infinity focus with the Gray. You aren't alone....

Yep, I definitely had a similar idiot-Eureka moment the first time I put my 65mm on mine.

Thank you, your honesty regarding your experience comforts me very much ... I'm not alone
