john_rogers8 Posted May 23, 2004 Share Posted May 23, 2004 I just shot today with a newly purchsaed used 645 pro, not TL. I have the #2 winder with cable to cock shutter on leaf shutter lenses which i will refer to as LS. I put body shutter speed at slow shutter speed, dialed in the shutter on lens to either 1/500 or 1/250, camera shutter on 1/125 or 1/60. I got a lot of half frames- half of the image recorded on the film and half was cut off. any idea why? what can i do to make it work? I wish i could test for sync by taking off the back and looking thru the back of the camera body. I set the camera body shutter release onto the white dot, i dont think that was a problem. Is there something i need to set or do to make the camera shutter open first and not get in the way of my image? this is super frustrating. On the lens, theere is that green "F" to the right of the shutter sppeeds. what is that used for? I thought i could put it there when using the #2 winder, i had heard that at that point you just need to set speed on camera body and it tells the lens shutter to shoot at that speed?? My manual does not say how to do it. I had about half of my shots ok and the rest with that half blocked image. Help!!! how is it properly done? thanks, john Link to comment Share on other sites More sharing options...
steven_muncy Posted May 24, 2004 Share Posted May 24, 2004 If set as you suggest in your post (1/125 second and Lens set to F) then half frames are expected. The "F" setting is for "focal" plane shutter. When set at F, the leaf shutter should NOT be active. The focal plane shutter always fires. With the winder(401) and cord attached to the lens, and the lens' shutter speed set correctly, the camera should set the focal plane shutter to 1/8 second. (perhaps slower). Try a few exposures at a higher speed setting on the body, then a few with the body speed set to 1/8. This would test for the appropriate signal. If there is a difference (still getting half frames) the cord or other connection may be bad. I don't know enough about the electronics to know if something else would also be apparent. Remember the flash synch goes to the proper shutter. The connection on the lens when using that shutter, and to the body when using the focal plane shutter.

shiver_me_timbrrrre Posted May 24, 2004 Share Posted May 24, 2004 Set the focal plane shutter to 1/8 sec and you will be fine. Link to comment Share on other sites More sharing options...
john_rogers8 Posted May 24, 2004 Author Share Posted May 24, 2004 thanks, thats it. I had the focal plane shutter set at 1/60 at the slowest, and had that problem half the time. Hope i dont get my ass sued over this, my camera manual does not address this at all! Thanks alot, will try a practice roll at 1/8 sec. No wonder my flash did not go off when the lens was set at "F", it could not sync at all with focal plane shutter due to that setting. Link to comment Share on other sites More sharing options...
