Hi,
I haven't done any closeup work since I had a 4x5" Sinar about 7 years ago. What I did then was add an intermediate standard and second bellows to ensure I had double the bellows draw. It was a little fiddly to focus on such a long rail but I ended up with some decent still life closeups on FP3000b (R.I.P!).
Now I'm on a 8x10" Tachihara and trying to get some similar shots as the weather is too poor to head out for landscapes. Somewhat embarassingly, I can't get to that 2x focal length 1:1 magnification! What am I doing wrong? I have about 500mm of bellows so I should have enough to get either my 121mm or 180mm to focus, maybe not the 250mm but should be close, right? All I get on the ground glass is a very blurry and far away looking rectangle. As a workaround I am using my 480mm lens at the minimum focus distance but obviously that's not magnified enough.
What am I doing wrong? My understanding is that image circle increases closer than infinity so since all my lenses cover 8x10" I shouldn't have any problems there.
