cbsmith Posted July 7, 2007 Share Posted July 7, 2007 I am getting consistent vignetting when using my 6x8 power winder on my RB67 Pro-SD. It is a recent purchase so I'm still getting used to all the quirks of the system. I'm using 90mm K/L and 180mm K/L lenses. Every frame has SIGNIFICANT vignetting at the lower corners of the frame, which reduces my usable image area to about the original 6x7 frame. Am I doing something wrong? Any help advice is appreciated. Link to comment Share on other sites More sharing options...
mag_miksch Posted July 7, 2007 Share Posted July 7, 2007 Maybe the revolving back is only 6x7? Link to comment Share on other sites More sharing options...
erie_patsellis Posted July 7, 2007 Share Posted July 7, 2007 You probably need to change the light baffle at the back of the body, when you remove the rotating back. IIRC, it should be labeled 6x8, otherwise you can only count on 6x7, I'm told. erie Link to comment Share on other sites More sharing options...
mark liddell Posted July 8, 2007 Share Posted July 8, 2007 I always wondered why I saw 6x8 written on the body of my RB. Thanks for clearing this up. Link to comment Share on other sites More sharing options...
mag_miksch Posted July 8, 2007 Share Posted July 8, 2007 You have a part called revolving back, release it with this bottom lever. Look at it, there you find "6x8" or not. Link to comment Share on other sites More sharing options...
cbsmith Posted July 9, 2007 Author Share Posted July 9, 2007 I looked, mine doesn't say anything about 6x8. That must be the problem. Thanks for the info. Now, to find a 6x8 revolving back adapter...Hmmmm. Link to comment Share on other sites More sharing options...
