the Hasselblad H4D-40 has micro lenses and it is supposed not to be good on tech camera when the back is shifted
is there any problem to use the H4D 40 with HTS 1.5 (and 28 or 35mm) ?

thank you

Not that I was ever aware of. I used the HTS/1.5 with a H4D/40 for both shift work and tilt work to increase DOF.

Also, even on a tech camera I believe you can use the Scene Calibration function in Phocus to remove cast and to equalize intensity. My rep showed me how that worked once but I never had to use it because I moved to a H4D/60 ... which I use on a Rollie View Camera.

and you never noticed something wrong with H4D 40 and HTS ?
 
No, I do not remember seeing any color cast issues. I believe using the HTS/1.5 is different from using a tech camera that isn't part of the H integrated system. The HTS/1.5 is part of the integrated H system and compensates for any issues ... but I am not 100% sure of this so it would be a good idea to contact Hasselblad technical services to double check.

digital back on tech camera

I use my CFV39 back on a 2x3 Technikardan with no problems. When using wide to ultra wide lenses some color issues are present but the scene correction tool in Phocus removes it with no problem. I was concerned whether it could handle a lens as wide as 35mm and recently purchased a 35mm apo Grandagon and found Phocus to deal with it with ease. In my experience the longer the lens the less issue. To use the tool I simply shoot an additional exposure through a milk glass filter at the same aperture and use this file to build a correction profile in Phocus and then apply it to all images shot at that aperture and camera settings (rise, tile, etc). It takes about five seconds max.
