CFV II 50C consultation (white balance, orientation and responsiveness)

[thesilentman]

Hi all,

I purchased a second-hand 907x a week ago, and I'm seeing some (non critical, so far) issues I'd like your opinion on:
1. Erratic white balance: same frame can be shot multiple times (RAW), each one resulting in a different white balance variation.
2. A small percentage of images (RAW) appear in a portrait orientation in Lightroom and Phocus, although they were taken in a landscape orientation.
3. I experienced one instance of the back slowing down to a point where each interaction with the screen took 5 seconds. "Fixed" only by turning off an on again.
4. I experienced one instance of the back shutting down completely after taking an image.

I'm currently using the back with a 503CW with version 1.4.0 of the firmware.

Any advice is highly appreciated.

I have never had any problems like that with mine. It sounds like you should send an email to Hasselblad and send it in for service.

Thanks. Do you use the back with the 907x or with a 500 body?

[mikaelo67]

I use it with the 907x body and my analog bodies. Never had an issue like yours.

For what it's worth - same here, never seen an issue like you describe, over 3 years of (moderate) usage with both 907x+45P lens, as well as on a 500-series body.

The latest firmware is 1.5.2, maybe you can try to install the latest version?

Good luck with your issues!

[thesilentman]

I reset the back to factory setting (should have done it earlier probably) and for now none of the issues I listed manifested themselves, at least not when using the back with the 907x.
Fingers crossed.

One thing that still bugs me:
The camera doesn't seem to respect the shutter speed limit settings for A mode.
The shutter speed goes below he defined 125 limit even when ISO is still below the defined 3200 limit.

Haven't tried the camera with a native lens yet, so using an adapted one, if that makes a difference in this case...

You seem to be having some unusual and unpredictable anomalies.  As you and others said before, you should reset the camera to factory settings and update the firmware (in this order).  Then you should test the camera with a XCD lens.  Make sure you have the latest version of Phocus S/W installed.  If you are still having unusual things happen, then there is likely a board issue.  If all is good, then is the time to connect to your analog body/lens.  For that you must select the camera or select electronic shutter.  If you have issues with the analog body/lens try to isolate it to whether it is with the camera set on the back or when you use electronic shutter.  As for adapters, they are nothing more than an extension tube with no electronics, so there should be no abnormalities there.  But, of course you will have to use electronic shutter.  And, I would not be surprised if setting for min/max function differently with the electronic shutter.  Again, this can be tested with an XCD lens by setting the back to electronic shutter and then testing the behavior.  The key thing here is to test the cameras function first with the lenses that it was designed to work with.  That will help you to understand whether you need to send it to service.  I hope this helps.

X camera suddenly shutting down comes from a battery failure, replace the battery if it wasn't the result of a discharge.

Only using adapted lenses means the body runs only on e-shutter

[thesilentman]

Thanks everyone, I'm still waiting for my 38V to be delivered, then I'll be able to test and report back (for those interested in the results).

[thesilentman]

Tested with a native lens and the shutter speed limit is now functioning as expected.

Last thing I want to run by you, since this is something I have never really had an issue with my Sony and Leica cameras.
Horizontal stripes visible when using high ISO values (not related to LED lights and electronic shutter) and a red cast that is usually more apparent near edges.

Below image was shot at ISO 800, added 5 stops of exposure in post to demonstrate the issue better.

[Georg Kovalcik]

"shot at ISO 800, added 5 stops of exposure in post" that´s equivalent to ISO 25600 then.
Personally I never have used ISOs that high, but as you mention Sony and Leica cameras, it would be helpful if you post a picture made with exact the same conditions from one of them too, to see what you expect as a result.

[thesilentman]

Thanks for the reply Georg. Attaching shots from my 3 cameras, with the lens cap on at ISO 6400, pushed 5 stops.

1 - Sony a7RIII
2 - Leica M11
3 - Hasselblad 907x, native lens, leaf shutter, after the camera was off for a while
4 - Hasselblad 907x, 503CW body, electronic shutter, after the camera was on and taking pictures for a while

(note these all have some degree of JPEG compression artifacts)

Hasselblad support reassured me that the last image from the message above is within spec.

If that indeed is the case it means the sensor wasn't designed with high ISO performance in mind, and shadow pulling in low light scenarios is an exercise in futility basically.

The 50 megapixel sensor is more or less 10 years old. The first digital back that came to market with it was the PhaseOne IQ1 50.
