Subject: [rollei_list] Rolleiflex Focusing



...and while I'm on the subject of the Rolleimeter.
While testing focus I noticed that what's in focus on my ground glass doesn't seem to jive with what my distance scale says - it may just be my lack of practice with meters. Things that are much further away than 20m are out of focus at infinity. What should I believe, the ground glass or the scale? 

Thanks,

Elias

Something is wrong. Check the ground glass to see if its cocked. The GG is held aginst the top of the finder by a couple of leaf type springs on either side. Push the GG with the eraser end of a pencil and see if it seats better. If not you must check the focus of the taking lens. This is done with a square of fine grain ground glass that will fit into the film channel. The infinity stop for the focus is the fousing knob itself. The the taking lens is set for exact infinity focus, the knob set against the stop, and tightened. The co-incidence of taking and finder lens is done by adjusting the finder lens. This adjustment requires removing the front cover of the camera. I've had ground glass screens get stuck a couple of times. Its easy to fix so I hope its that. I believe the finder hood should be open when using the Rolleimeter, it cerainly should not be tilted. There is an on-line instruction booklet for Rollei accessories that covers the Rolleimeter but I can never remember where it is. Its a site maintained by a member of this list.
