I've been using an old 127mm Rodenstock (off a Land Camera) on my Speed Graphic butnow comparing it to my new 300mm Fuji I can see the difference. Not that the 127 is bad, though. My frustration is that I want to get closer subject focusin g as I want to get the texture of the subjects and I need some suggestions. I only have about 300mm of bellows draw and use minimal movements. I can just bar ely afford a a new Rodenstock S 150 or 210 but can someone clue me in about G- clarons? What exactly does "optimized" for 1:1 mean in these lens and would that be the way to get closer focusing? Or am I not getting something here? Lastly, can someone point me somewhere where I can find or make an extension lens board for the 300mm? Thanks.
