Hi,
I am building a 35m lens adaptor and all is good. Tested it in its basic and 50% there. I have being playing with some old macro adapters i have to be able to focus the camera (dvx100 hvx200) to the ground glass. Now I have done it in a cheap way going back and forth. Is there a way (which of course i don't know) to calculate exactly which macro adapter I need (depending on Focal Length, distance). Because on the dvx100 all the way zoomed in I can't get it to work. i always have to zoom out a lot and bring the camera closer. I would prefer to be on the longer side of the lens for some visual things i need to do, of zooming in to the ground glass and still be sharp.
Any help would be great!
Thanks!
Miguel
