Zoom & Focus Demands with Fuji HA18x7.6BERD-S48

I've recently acquired kit listed below. I completely understood that the BERD lenses would work with zoom and focus demands, also auto focus. But, I cannot get the demands to make any adjustments to the lens. Iris adjustment (auto and manually adjusting setting on camera) does manipulate the lens. Demands do not, and pressing the focus button does not cause auto focus box to appear. Any help?

Check the servo switches on the bottom of the servo handgrip on the lens for zoom and focus are set to the 'S' for servo position rather than 'M' for manual. They need to be in that position for the camera to drive the lens.

Also are your zoom and focus demands LED's lit up white when connected and showing up when you check the pages in the camera's setup menu?

Hi Tim, thanks for the reply.

Both switches on handgrip are set to S. I can confirm that the handgrip toggle will control the servo for zoom, and the focus ring cannot be turned by hand, as it can be when on manual.

White LEDs are solidly illuminated on both zoom and focus demands. The buttons on the zoom demand appropriately trigger recording and program feed. Setup menu appropriately shows zoom and focus demand. I can even change the zoom dial to control iris and it works.

Check in the lens page in the camera slate - if the lens is showing as 'analog b4 lens' you should check the dip switches on the Fuji lens itself.

When talking analog there is only iris control. When talking with serial digital communication you should get full iris, focus and zoom control as long as the lens has the relevant in-built servo for each... and given yours is a Fuji with BERD in the name that should definitely be the case.

Sure enough, it is showing as "Analog B4 lens". However, it doesn't seem that there is any dip switch that would control this. Switches I see:

1 Q-Z On (Quick Zoom)
2 VTR > Q-Z (changes VTR button to quick zoom)
3 RET > Q-Z (changes RET button to quick zoom)
4 PRE ON (?)
5 C-Z ON (cruise zoom)
6 I-COMP ON (iris compensation for 2x switch)
7 I-A-M CHG (swaps the position of the iris auto/manual switch)
8 FUNC SW (zoom limit enable - I think)

I fooled with all of these to no improvement. Have I somehow purchased a BERD lens that doesn't actually allow camera control? Just my luck.

I'm my further pursuit, I've found the following document in some other posts: http://www.dvinfo.net/forum/attachments/sony-eng-efp-shoulder-mounts/1159d1162992705-getting-creating-lens-files-serial-data-communication-lenses-sony-cameras.pdf

Reading the document, it appears that serial data communication may already be enabled on my lens, as the position of iris and RET/VTR buttons are operable.

I've tried both the enable and disable procedures, but I neither ever get a green LED nor does any behavior change.

Is there a bottom set of four switches under those 8 top switches that you mentioned?

If so the top one in the bottom group of 4... in position 1 needs to be set to 'On'. It is the Camera Communication On/Off switch.

You may need to power cycle the camera, or unplug and re-plug the Hirose after changing this so the camera re-initialises with the lens.

There is not.

is that the old SD lens? https://videobrokers.com/index.php?controller=attachment&id_attachment=69
I'll keep trying to find the correct manual

also give this thread a look https://forum.blackmagicdesign.com/viewtopic.php?f=4&t=70896&start=50

Thanks for the reply. I'll take a look at the thread.

It is an HD lens.

Did you get anywhere with this? Currently having exactly the same issue as you!

Sadly, I found I had a revision that wasn't capable of the features. Even though the model number itself matches one on the supported list, evidently there are variations/revisions of that model number and no clear marking to discern.

I was able to work with the shop from which I purchased the lens and they were able to install a control unit of a higher revision and the same model that works great.

Do you remember the revision number that works well with the controls?

Hi all, I'm in need of some assistance with this now too. I have two different lenses, HA22x7.8BERD-S48L and HA20x7.5BERD-S48 and I can't get either one to work with the zoom and focus demands. I do have the zoom and focus set to servo, and the led lights up on the zoom and focus demands. Both lenses report as analog B4 lenses in the slate. They both have the set of DIP switches that look like the original poster. What are the odds that both of these would also be a revision that is not compatible? I must be doing something wrong... I'll be able to get by with one of them because I have Fuji's own focus demand and a varizoom, but I sure like the feel of these Blackmagic ones. I'd love to be able to use them.

Thanks,
Stephen

Any updates on this?

You need a Len’s with a digital board which supports full camera control. Unfortunately my Len’s (ha42) only has an analog board, so only the iris can be controlled by the camera.

Spent many hours on the phone to Fuji to confirm this and without a 8 grand upgrade, it’s physically impossible. It needs a whole new pcb.

Also I should add, the camera can assign fuctions to the vtr/rec buttons still, so I’ve using the vtr button on the Fuji zoom Demand for talkback.

Do you know if lens revision S58 will work on the G2?

This is a bit less expensive solution than '8 grand upgrade' viewtopic.php?f=4&t=165607

It is not available as a product right now, but will be working on it during October.

It works with any B4 lens that has analogue control for Zoom, Iris and Focus. It has been tested currently with URSA Broadcast G2 and Micro Studio cameras, but as far as I know all BMD cameras that have B4 have the same protocol.

Wow!! This looks impressive! Is this something you’ve made?

Just to give a quick update, the Fujinon HA18x7,6 BERD S58 is working with the Broadcast G2 including the Blackmagic Zoom and Focus Demands.

I will post some pictures / videos the next days.

We just recieved 3pcs HAs18x7.6BRD-S48 lenses and initially they did not work properly with the URSA Broadcast G2. However we found a dipswitch (which were not on your pictures) that enabled serial control and thus USB Zoom and Focus Demands.




While looking for the solution we also stumbled across this. Have you guys tried it?

We have an HA22x7.8BERD-s48. We were having this exact issue where our zoom and focus demands didn't work with our Broadcast G2 and our model of the lens didn't have the digital board with the 4 extra dip switches. This diagram from Fuji was what did it for us! Enabled serial control and enabeled full functionality with our zoom and focus demands.
