To Tom and the group,
I bought an 80mm Hartblei tilt/shift lens, hoping I could get back some view
camera movements which I lost when I converted to digital.
The Hartblei is an interesting lens, a medium format optic in a Dr.
Frankenstein mount. It seems as sharp, and has better light coverage than my
100mm macro. But whatever DoF I seem to gain with a lens swing, I lose with
the limited f22 minimum aperture. In other words, my 100mm macro at f29 or
f32 is sharper overall than the Hartblei swung at f22.
I was an instant digital enthusiast after seeing the first few images from
my 1Ds. But when it comes to close, technical photography, I miss the
flexibility of my view cameras.

They wouldn't work.
What kind of manual lens are you trying to use with the tubes?
