How much play on the focus track?

[mihag]

I wonder how much play (if any) is normal on the focusing knob on a brand-new Linhof Kardan re camera? Linhof state that their Kardan re uses new play-free solid brass micro drive for extremely smooth focusing of the camera on the monorail: http://www.linhof.com/kardan-e.html
I feel some play while focusing and fear it will get worse with use.

On the left side of the focus block are some small allen screws. These allen screws adjust the tension of the brass plate in the focus drive against the rail. You adjust these by making very small turns with the small allen key that is suppied with all new Linkof Kardan cameras. The instructions are included with the camera.
The camera should be properly adjusted out of the box but anything is possible.

It doesn't work. The allen screw stiffens the the drive but the play on the focusing knob remains. Even when the focus is blocked with the smaller knob, the focusing knob still feels a bit loose - it can be turned for 0,5 mm each way freely.

Without seeing your camera I can't tell you if the "play" in the knob is normal or not. Are you anywhere near a Linhof service center or importer/distributor? If so then let them see it.

[mihag]

Yes I am, but it will have to wait over the holidays. I fear our distributor will only try to send the camera back to Germany. The camera is perfectly functional as it is although the focusing isn't extremely smooth because of the play in the knob.
Thank you.

I have send two short videos showing the problem to Linhof, including the describtion of one of the front standard knobs that has a hard time braking the vertical shift. I'll report back as soon as I get their reply.

Keep us updated, mihag - anyway, luckily their service is usually very fast in Europe. Perhaps you might give them a call and check if it is OK to send them the camera directly for repair?

A week has passed and I got no reply to my email.

Mihag, I highly suggest to give them a call.
Linhof sometimes seems quite busy, but they were always helpful when I called them. Email is, unfortunately, still not regarded as an important medium of communication in many of these old companies (e.g. Gossen). I often made this experience.
You will most likely get Mr. Biel on the phone - he is a very nice guy and will definitely be able to help you.

Hi Jan, my experinece with Linhof is positive. I've been on the phone with Mr. Weigand (I don't know his position) before and he was extremely nice to talk to - to the level my German permits. I'll give them a ring on monday.

Cheers,
Miha
