HASSELBLAD 907x Major connection issues

PSS

Member
I just did a shoot, on location, total of 2000+ shots, 1500 on 907x, rest on 1XDII...i did get one lens connection error on the 907, restarting the camera fixed it ...i think i made it happen by moving the camera (adjusting the position) by holding it by the lens/907x (the 45P) while on the ball head....i don’t think it (the connection between 907 and c50 back) likes being “flexed” in any way.....
the other thing i noticed is that while i am perfectly capable of seeing the scene through the EVF of the 1DXII, the rear LCD is very dark....and i did have my live view settings set correctly.....
peaking did work ok....i tried to use it on my last shoot and a few sets of shots were simply way out of focus...i probably adjusted to it a little? Paid more/better attention?
another observation is that the remote seemed to add just the slightest bit of shutter lag, I did use it before and had great results (hit every jump at the perfect moment) but it seemed to lag a bit now, ended up not using it, was wondering of anyone else has had a similar problem....
overall the system is great, color is insane, detail is great, speed (with sony tough cards) is good....for me the best available right now.....

GAME OVER ? ? ? . . . . . NO .

After my 907x kit returned from Sweden , I only had little time to do some intensive testing . But I could do a firmware update as you can see here .
I described this in an other thread .

907x FIRMWARE.01.jpg

Short tests looked fine and I was happy .

Today I did more tests and was pretty fast very disappointed .
After power on I found , the CFV does not see the lens as attached . For a very short time I could see a message , lens initialization . . . . . Too short to take an iPHONE image .
But for sure , after several POWER ON actions , the lens was not detected and therefore you can not do any shooting .

907x FIRMWARE.02.pg.jpg

No 907x and no lens detected . Result is a screen like this and similar others .


907x FIRMWARE.05.jpg

Then I often get screens like this one and similar other ones .

907x FIRMWARE.03.jpg

907x FIRMWARE.07.jpg

or this one or similar ones . Pressing the release button results in no action as obviously the lens is not recognized .

The repair report from HASSELBLAD said , that the FPC module in the 907x was replaced .
The issue does not turn up like the original issue , does not turn up when touching the 907x or the lens or the back .

Additional to the above , I found , that the issue is seen much more often , when the battery power drops below 45% . Battery came with the kit .
I don't know , if that is relevant for the above described issue . The camera should not fail with a battery load of 45% .

Does this look as a lens issue ? ? ?

I have the same issues with the replaced 907x. I suspect as reasons oversensitive contacts between the 907x and the back as well as a low battery. I am not completely sure, but the issues might have started after the latest software update. I have not yet contacted Hasselblad but will do in the upcoming days.

Jürgen, I'm sorry to hear of the recurring problem. In replacing the FPC module, did Hasselblad return your original (ie, same serial number) front 907X front body?

Thanks for your post . After the 907x kit returned from Sweden , I made a couple of test shots and found , that everything works as it should . Then I made the firmware update
to the latest version . Successful for CFV , 907x and lens .
Only yesterday I found enough time to do some more shots and experienced the above described new issues . I can not tell if the latest firmware has any influence .
I am looking forward to see what the HASSELBLAD specialist will find .

Hello Gregg
Used lens is 4/45P .
The FPC (foldable printed circuit) module was replaced in the 907x . I got the original CFV and 907x back . In the worst case , if your complete kit was replaced , you could , with bad luck , get an other brand new kit showing the same syptoms . Therefore I found replacing the module is O.K.
The symptoms I see now , are different . No more bad contact indication , when touching the Lens , 907x or CFV , but an intermittent issue . The attached lens is not recognized after power on . This results in many different indications on the screen . iPHONE images available . This is , as I found this morning , independanet of the battery load . Power on failed three times at a load of 92% , 85 % and 81% but happens more often with a low load . Below 40% .
I will contact HASSELBLAD Sweden by tomorrow and give feedback with what they say .

It seems that Hasselblad’s minimal fix for the defect is too minimal, and replacing the entire 907x would be a better remedy until they ascertain all causes of the problem. I hope they will agree to send you a replacement 907x unit.

Argh. Sorry to hear of it. I'm sure Hasselblad will put it right, it's just a PITA in the meanwhile. :(

HASSELBLAD service and support requested to have the complete kit 907x + the 4/45P lens onsite for investigation .
They have not seen the reported issues after a FPC module replacement yet .
They sent me all documents for a DHL express parcel pickup tomorrow afternoon .
Waiting for pickup .

really sorry to hear, does not sound acceptable to me at this point....
I did have another issue with the 907xC50 today, just running around, not a job but the body clearly did not recognize the lens, AF did not work, I did not get an error message, restarting did not help.....taking the battery out eventually did....I do believe the issue is contacts between the 907 and the back...I don't have any issues at all with my X1DII and any of my lenses and the issues I have with the 907C50 seem to start when I firmly handhold and manual focus and probably put some pressure on the body/back connection....
so far I haven't had to send it in, always have been able to get it back to life and once it does come back it usually works fine for the rest of the day....but at this point I am definitely keeping an eye on it, if anything is remotely repeatable I will send it in when I know I won't need it for a little while.....
still love the camera, used the distance scale for the first time today (with peaking) definitely helps....

The symptoms you describe are typical for the issue described in this thread . They will get more serious .
I recommend , you contact your dealer or HASSELBLAD depending on the support structure of your country an give them a detailed description .

I agree ... No good reason to wait if you have another camera to take up the work in the meanwhile.

I suspect with the craziness of the pandemic hitting everything this year and all the consequent perturbations in personnel and supply, the production change in the 907x standard edition for the new LCD just threw things a little out of wack. I trust Hasselblad, however, and they've been addressing the problems in an efficient manner.

May all these issues disappear into the smoke of history within the next year. :D

I have also noticed issues with the Hasselblad remote. Sometimes I press it and it does not trip the shutter and I have to try once or twice more. I also find that there is lag even when the shutter is tripped on the first press. This would obviously be a serious problem if you are trying to track movement or gestures and time your exposure. However, the remote sure is elegant!

I have read the posts in this thread with great interest as an owner of the CFV50c and looking at a possible future upgrade to the CFV50c II. I have owned and used the CFV50c since it first hit the market in 2014, using it for six years flawlessly on tech cameras (ALPA, Sinar and Linhof) and V Series bodies (503cx, 501cm and FlexBody). It appears to me the problem must be with the 907x since it is the bridge enabling the lenses and back to talk to each other. Has anyone experienced any issues with CFV50c II on V series or tech cameras?

Hello Darr

Yes Darr , I have used the CVF II 50c on my various V-SYSTEM cameras , on my ALPA cameras and also on my ARCA SWISS 6x9 metric .
Never experienced an issue here . All works as it should .
The issues I experienced turned only up with the 907x / CFV II 50c as a standalone system . Currently I only have the 4/45P lens , but I have read , that the issues are also seen with
other XCD lenses . If that is true , and it looks very much so , the 907x will be the failing unit .
HASSELBLAD replaced the FPC (Foldable Printed Circuit) module in my 907x which solved the original issue , but now I get the "lens not detected" issue .
My kit 907x 50c + the 4/45p lens were picked up by DHL Express yesterday to be shipped to HASSELBLAD ( again) . I am curious what the new investigation will show .
Hardware or Firmware . ? ? ? :oops: I will report the result . Hopefully soon .

Thank you Jürgen.
I appreciate all the information you and others are sharing regarding the unfortunate technical issues with the 907x.
New technology in need of tweaking obviously, and I am sure Hasselblad will get it all worked out.

Best to you always,
Darr

The issues all seem linked to the standard edition 907x, and seem to be centered around the early units in the production run. My 907x Special Edition has not had any of these problems. The only issue I had was right after it was released, still with firmware 0.x, and that came down to what I suspect was an uninitialized position sensor (the gizmo that detects whether the camera is in vertical or horizontal orientation). A chance forced-initialization of the chip (by calibrating a position to consider "level") fixed it, and since the first firmware update, it has not recurred.

The back has been 100% reliable used with both of my 500CM bodies since day 1.

The problems with the standard edition model all seem to be related to the back's internal flex board and its connection to the 907x body, related to the adoption of the new LCD and its supporting circuitry. It's probably a production assembly/variance problem; I've seen this before when I was working and a member of the production ramp team for various computer and display products. With all the disruptions and issues going on this year, it doesn't surprise me although it's certainly unfortunate (and a PITA for early adopters).

I'm sure Hasselblad will nail it and work it out for everyone. Like with so many things this year, we need to be patient and work with them. I'm sure it's not easy for them either, given the weirdnesses thrown into personnel and materials supply in the current pandemic world.

Thank you for your post .
My parcel with the 907x kit + lens is picked up and on its way to Sweden .
With 30 years of computer hardware and software service , I can understand the trouble the HASSELBLAD specialist are in and therefore you find me here very patient .
Tomorrow I will get the XCD 3,5/30mm lens and will put it in my glas cabinet to join my V-SYSTEM lenses . So the lens is not alone while waiting for the 907x to return .

Darr, I briefly used the CFVII (Apollo edition) on an Alpa 12 plus and STC. Everything worked as it should! The integrated battery, better screen, better live view, and electronic shutter are definitely worthwhile upgrades over the original CFV50c IMHO. Other features, like dual card slots and mobile tethering to phocus mobile, also might be helpful depending on your needs.

I also had no issues with the 907x, but then again I had the Apollo SE, and as Godfrey had noted, the connection issues people are experiencing seem to be with the standard edition.

HB have admitted the issue is (was) related to a problem with an electronic component with the early production models which has been corrected. Looking at these posts it appears there might be secondary issue relating to failure with the 45P after upgrading to lens firmware 0.1.26 - but that is purely speculative.

My 907X has been working with no connection issues on my 45P, and now second hand 80, since being exchanged by HB. I have not updated the 45P firmware from 0.1.24 (and have no intention of doing so). I am on 907X firmware 1.4.

There have never been any issues using the back only on film camera bodies.
