<p>I apologize if this question has been asked, but I think I've read every question regarding the Rapid Omega on the site. But, I know I've missed some, probably the one question I need.<br>
I have been trying to remove the Series VI filter ring from my 90mm lens , to let me use 49mm filters. I have tried every trick I can think of plus all the tips I can find here. But then, I read one post here which stated that the DOF ring and lens shade must be removed by loosening up 3 tiny set screws. I found the 3 tiny set screws, they are so small I couldn't tell if they are screws or what. Do I need to remove the lens shade and DOF ring ? My last attempt consisted of making a 1 7/8 wooden circle and using a rubber jar opener beneath it-- no work . Its either stuck very well, or ?<br>
thanks--tom</p>
