close focus lens for 4x5 ?

[buggz]

Rick,
Thanks for the information about the bellows extension affecting exposure.
I had only briefly read about this. I need to read more, I bought the books.
I experienced this, new to me, this weekend, I had to go through a couple of wasted Fuji instants to get the exposure I wanted.
It didn't match the readings from my DSLR.

I have one question, at what point does "the bellows exposure factor" come into play?
When you add the extension rail? Or, most probably, some factoring of lens focal length?
Again, I need to actually read the books I have purchased.

As for macro work using the Sinar f2. I am not looking for that.
All I wanted to do was to get close enough to "fill the frame".
Which I found out I can easily do w/ the gear I have.

Thanks for the macro lens suggestion for the DSLR.
That one has been on my list, as are many others.
I do already have several macro lens for my Canon 5DMkII already.
ALL of them are NON Canon lenses.
I have long learned the usage, and great enjoyment of using different manufacturer glass via adapters.
I love the "old" manual focus lenses, they render different than the stale Canon glass.
Minolta glass is great.
Heh, I have even been trying all these brass barrel lenses I seem to be "collecting", looking for "that look".

The Rodenstock Depth of Field Scheimpflug Calculator calculates this on the depth of field side at ratios from 1:1 to infinity at 0 tilt to 40° of tilt and for film sizes from 35mm to 8x10. If you do not know this calculator it a a two sided, pocket sized, rotary calculator for photography. One side computes Scheimpflug angles and the other side DOF (including exposure corrections due to bellows factor). It has also been sold with the Calumet name on it as well as the Sinar name. But it is a Rodenstock product.

Cool, do you sell these?
