Thanks a lot to all for the very useful information and tips. We are hoping to run some tests before the end of the year and I’ll post updates.

Anna, We moved from the H4D CCD multi-shots to the H5D CMOS multi-shots did a color accuracy test before purchase. After custom profiling (BasICColor) the results (color and tone response) were practically identical and verified with Golden Thread software as well as Delt.ae. We've seen consistent results even using the Phocus profiling in V3.0 with the CMOS. We did not compare canned profiles with the two backs. Note that the sensors size of the CMOS is slightly larger so it will effect focal length. Lastly the CMOS in the H5D has the benefit of a much improved live view feature. If you'd like to see the test results I can probably dig them up for you.

I think Sony make the Hasselblad sensors, if true they have a video article about it here: https://pro.sony.com/bbsccms/ext/BroadcastandBusiness/ccdcmosimagers.shtml Best regards Tony [cid:image001.png@01CF86F9.22C2BC80] Tony Harris Digital Media & Photography Officer Government Art Collection tony.harris @culture.gov.uk<mailto:[log in to unmask]> | 020 7211 2426 [cid:image002.jpg@01CF86F9.22C2BC80]@govartcol [cid:image003.jpg@01CF86F9.22C2BC80] /governmentartcollection | www.gac.culture.gov.uk<http://www.gac.culture.gov.uk/> On 21 October 2016 at 17:21, Arca, Anna <[log in to unmask]<mailto:[log in to unmask]>> wrote: Hi All, I was wondering if anybody has been comparing image quality and specifically color accuracy between the H4D CCD 50MPixel multishot sensor and the new H5D-50c CMOS multishot sensor. Here at the National Gallery we don't see a strong reason for moving to CMOS sensors, but it seems like the CCD sensors have been discontinued and obviously we need to keep our studio running with reliable gear. Also it would be great if anyone could advise about their experience with 100MPixel single shot sensors. We will be hopefully be running some tests soon, but any input would be very helpful.
