I have been using a Hasselblad cfv-39 Digital Back with great success over the last two years. Used the Digital Back mostly on a Silvestri technical camera and on a 503 CXI body.
For the last few weeks I have been using a Phase IQ140 V mount Digital Back on a 503 CXI body. The images came out so much better I figured something must be wrong with the Hasselblad Back.
Using the Hasselblad cfv-39 with a 40mm CFI or 50mm CFI lens I cannot get sharp infinity images until I stop down to F8. Using the Phase IQ140 V mount digital back I get sharp images with the lens wide open.
The issue is consistent across a few 503 Hasselblad bodies and a few wide angle lens.
This is not such a big issue for me as I normally have the lens stopped down to F8 or F11 when using a Hasselblad body. But it probably limits the resale of the digital back. Of course when using a bellows Flexi Cam you can focus past where the infinity position stop is, so its not a problem.
Wondering if I should send the Digital Back to Hasselblad to be recalibrated. It was in this state when I bought it but it's taken me a couple years to work out there is a problem so the guarante will have expired. I think the sensor needs to be slightly further away from the camera ?
Anyone any experience with getting a Hasselblad back recalibrated ? any ideas of cost and time it takes.
Any advice on if its even worth doing.
Regards
Neil
