I have a problem with the smoothness of focusing my 4x5 Tachihara when doing closeup/macro work. It isn't nearly as pronounced with regular shots. I have had an old Graphic camera before and it seemed very smooth. Even my old Kodak 2D 8x10 is smoother. When trying to focus the Tachihara, it is very difficult to turn the knob just a little without the knob, or camera, jerking. I have tried using soap, different waxes in the gears, etc. But to no avail. I have tried lifting the front of the camera while focusing, thinking there was too much weight on the front end. I have even checked the rubber washer on the knob, and it is fine.

Other than the jerkiness of close focusing, I am very pleased with my Tachihara.

Are there any other suggestions I might try.

Thanks,

Jay
