I've done enough test now to say that the HTS with 100/2.2 can equal the 120/4 Macro in sharpness, etc.Would be VERY interesting to get some impression about HTS and product photo. I'm about to sell my Cambo Ultima on ebay (not using it enough). I'm using the HC 120, really superb lens, but limiting compared to a tech cam.
I'm really skeptical about the quality results of a 100mm + HTS compared to a 'naked' HC 120mm...
Depends on your applications doesn't it?HTS is next on my wish list though i am still debating on the 120 macro
Even if one could use the 120 on the HTS, I'd be reluctant to do it because it is such a huge and heavy lens. The torque on the little HTS would be substantial ... and even though it is built very robustly with very nicely dampened, heavy-duty gears and tight locking mechanism, it would easy to see one releasing the lock and the lens falling forward in some circumstances.Hasselblad makes a table with the addition of each of their extension tubes and each in combination with each of the HC lenses to get the specific maximal magnification. I can look for it if anyone is interested. I have the 120mm macro and have used it with and without the extension tubes. Likewise i have used the extension tubes with the 100 2.2 and 50-110mm when traveling without the macro. While the extension tubes work well with the non-macro lenses, my major complaint were related to some falloff in detail and distortion at the edges of the image. I was using the H3DII-31. So probably more noticeable on fuller frame HC cameras. Nonetheless, the 120mm macro is really an outstanding lens and probably one of my favorites.
THe HTS is great but it is unfortunate you cannot attach the 120mm macro.
Actually, I could have gotten closer, but not much. With the 52mm it was about the same as the macro ... but tilt was restricted some. I need to get the 26mm tube for something in between.marc:
i'm assuming you needed the 13 tube because you couldn't get close enough using the 100 to fill the frame?
is there a change in minimum focusing distance with the HTS?

That it is David. In fact my 120/4 has never been out of the studio, except maybe a few shots in the yard. I doubt I'd ever travel with it unless absolutely necessary.I shot this lens today on the H4D 40 and was amazed at how big and heavy it is. Super optic but not what I'd call a carrying around lens.
Not sure what you mean by "sharp vision" and "auto"?how are you judging focus? just sharp vision, auto or are you looking at test shots?
Well, I can tell what is in focus in the H viewfinder pretty well with the lens at full aperture ... but at f/18 it is difficult to see what the DOF will be because when you stop the lens down any viewfinder gets pretty dim. The waist level finder is a bit easier for this.that clears it up thanks
here is my take:
HTS disables autofocus and the focus assist (the "auto" questioo)
you are looking at test images on your monitor, since the viewfinder is not enough (the sharp vision comment)
your results are impressive
With Live Video, Phocus will try and choose the optimum aperture for your lighting. Note Aperture is set to 'AUTO' in the camera control menu. It takes a while to adjust....Marc, I find shooting tethered with Phocus quite a challenge too...the image I get on my live view screen is b&W(? looks b&w), and even when I judge it to be sharp optically on my viewfinder, when I switch to live view...and boy it takes a while for the Hassy to settle down in live view mode (I figure it adjusts the aperture in steps), I usually get a blur picture which I find hard to judge. The little graph is of little use, as that too goes up and down like the stock market.
As a result the shots of watches are judged with just the optical viewfinder...and I find them rather ok in focus...any comments?
100% crop...
For me, I would still want to get the 120macro and use with extension tubes...as I want to get the crop pic above, and print without resizing up to A2.
