Great news. What you using as a copy lens? Is it that Leica R?
I just ordered a 120/4 CF Makro lens for my Novoflex copy stand arrangement with the Hasselblad automatic bellows. I’ve been using a 150 until now and it’s been fine, but it results in the camera being cranked way up in the air, so I’m hoping that the 120 will bring the camera closer to my light box. It’s supposed to be a great lens - it was a tossup between it and the 135 bellows only lens, but I opted for the 120 because I thought it would be more useful.
I've done copy (and macro) work with the 907x using three lenses to date:
- Leitz Macro-Elmarit-R 60mm f/2.8
- Leitz Macro-Elmar-R 100mm f/4 in bellows mount with Focusing Bellows-R
- Hasselblad Makro-Planar 120mm f/4 + Hasselblad Extension Tubes
The MER60 works well and keeps the camera elevation low (makes the copy stand more rigid not to have a big weight up so high). The MER60, though, has a bit of field curvature and barrel distortion when used for flat art like a negative or print; it's really at its best for 3D subject matter.
The Makro-Planar (MP) 120mm is a superb lens for close up work (very flat field, very crisp right to the very corners of the frame, etc) but it does make the camera configuration pretty bulky and needs a good bit of elevation on the copy stand to get to the magnifications required for 6x6 negs, SX-70 and Go prints. Lots of good working space for lighting, however, but I am careful when using it to use a remote release or Phocus to trigger the shutter—and NOT MOVE—so as not to induce vibration into the copy setup when working in the 1:3 to 1:1.5 range needed.
The MER100 falls between the two. Along amongst my adapted 35mm lenses, it shows virtually NO vignetting on the 33x44 sensor (at least at my most used magnifications) at all, and is sharp/contrasty corner to corner. It requires a bit more elevation than the MER60 but not as much as the MP120. The Focusing Bellows-R provides excellent, useful controls with this lens, including a means to flip the aperture wide open for focusing checks and then drop down to taking aperture in one press of a button. It also allows me to rotate the camera in click-stopped 90° orientations to optimize for different format captures and their alignment to the camera sensor. The bellows also include a micro-focusing rail built into it, and a selectable rail with mm of extension and distance/magnification numbers for 100, 90, and 135 focal lengths. The only issue with it is that it is similarly a bit on the heavy side, like the MP120 with all those extension tubes and the adapter.
For the prints I copied yesterday I used the MER60, added the lens correction profile in LR, and then added a +5 distortion correction to remove the barrel distortion. The results are very good, with excellent coverage in the central square of the field, and now that the camera is behaving itself properly on the copy stand, the capture process proved quick and easy.
I'll post a couple later today, presuming I get some time to do rendering. Right now, I have two rolls of 120 film that I want to process...
