I thought quite a bit about your bellows and focusing rail comments, especially about having spare bellows parts. But
as to focusing rails I'll probably stick with my little used ebay 2-axis setup. It doesn't operate quite as smoothly
as the Oly focusing rail but it's quite close and not bad. Both have helical racks and drag adjustments. I found
that I couldn't tightly lock the ebay rig and thought that might be a difference but then found I couldn't tightly
lock the Oly rig either.
I have one of those, too. Not bad, but more slop between axes than I would like. Twist one against the other - big
movement, at least on mine. When I did use it, long ago, I seem to recall that the directional slop tended to defeat the
purpose of the sideways adjustment. Touch the camera to adjust it and the left-right framing changed. I remember being
disappointed/annoyed.
Unless I need the sideways movement, which is really, really unusual, I'll
stick to the Oly.
But I'm still thinking about the spare parts angle. You can typically buy the complete bellows for less than the
focusing rail but you do also need a focusing stage for use as a rail alone. Something I do have but not included with
a bellows.
Sure, but doesn't everyone have one of those? :-)
