  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Birger Lens Mount & Follow Focus

Do we have any price on the mount or follow focus unit yet?
 
If the Birger wheel could incorporate a second mechanism so that it could do both focus and iris, such as Bebob's Foxi, it would be great (see link below).

I agree that having three buttons in the adaptor is not ideal, it would be better to have an analog control such as a wheel for iris control in it, but buttons are better than nothing.

I think it does have the wheel as the primary method of setting iris, the idea of the three buttons is you would still have iris control even if you didn't have the remote unit hooked up - say in a single camera handheld situation.

Erik can confirm this. BTW Erik if you could put a three (or would it be 4) conductor mini connector on the mount too it would make my life on the underwater housing side really easy. With that said we will probably work through the remote you provide, but even there a separate connector that would let us parallel those switches/pots would really help. Or is the remote just the switches/pots and the RS232 stuff on the mount itself - i.e. where do the RS-232 commands originate?
 
AquaVideoRed206,
This is not what I meant, sorry if I was not clear. In my second paragraph I was talking only about controls directly in the adaptor (without an external large wheel connected to it). The BirgerEngineer mentioned the possibility of putting three buttons directly in the adaptor to control the iris. I believe that a small wheel directly in the adaptor, or around its circumference as already suggested, would be better, but if it is not possible, the three buttons would be better than nothing.

I think the key is the 3 buttons are an easy, last minute, (better than nothing) addition to the product, but a wheel would be a substantial electro/mechanical design/engineering task.

Correct Aqua. These last minute changes are: the programmable buttons on the mount; Finner's whip attachment; TJ's toolless hinged clamp.

I thank everyone for their patience with us as we get this announcement, final pricing and the reservation system ready to go.

I am very excited by all of the emails and PMs that I have received regarding this system.
 
#8 Tests

#8 Tests

Hi Erik,

As you probably know, Red #8 is going to be tested in lots of configurations with lots of lenses soon after it is shipped. Many here will make decisions based on those tests. If for some reason you are not ready to ship with the first cameras, you should make a priority to get your mount to these guys so it will be included in their tests.

So can we reserve and is the price up some place?

Looking foreword to your announcement Eric. Thanks for your work and contribution to the forum.

In addition to the open Birger protocol, the lens mount also speaks Fuji and Cooke-like lens protocols so it can be used with existing lens control, data-logging and data-display equipment.

Is it be possible to take data from a Canon or Nikon lens and convert it to /i data for the camera to record?

Afterall the Canon and Nikon lenses must be sending such data to their respective SLR bodies, could it not be intercepted and converted to fit with the Cooke's /i standards?

This is the intention. The controller will speak a protocol that the camera will understand, to allow for data logging. /i compatible is what I was referring to as "Cooke-like". This protocol does not allow for control of the lens, only logging of data.

The broadcast lens protocols allow for both control and logging of data. The SuperGrip is a control device, so supporting only /i is not good enough...

The Birger lens controller platform is basically a Babel Fish.:nerd:
 
So the advantage of using lenses with /i will be lessened because Canon and Nikon's will effectively be logging the same data then (focusing distance, aperture, depth-of-field, hyperfocal distance, serial number, owner data, lens type and focal length in both metric and footage measurements and for zoom lenses, the zoom position.)?

That's excellent, I hadn't really understood it when I first read it.
 
Hi Erik

will you be at IBC Amsterdam? Or (it's a long way to come), will we be able to see the Birger mounts on the RED stand?

I don't know how that would fit with RED's business plan, but I think a lot of us are planning on the Birger mount being an integral part of our RED camera kit
 
Eric, will the follow focus be reversable?

In other words at the flick of a switch the user can turn anti-clockwise or clockwise for either focus long or short.

Also can the distance turned on the follow focus to the movement of the lens be altered for greater accuracy on shorter focus pulls?
 
How does this setup all work exactly? Please forgive my ignorance but I've read through this whole thread and I'm still unsure as to how it all comes together and functions.

I get that the unit is not geared but directly controls the motor of the lens via bluetooth. So how is this done? Is a remote provided, or do we have to have a laptop with software installed? with the remote can you set focus points for it to go from and to? Do you have timings over this control for fast or slow focus pulls, or is it a fixed motor speed? Do the EOS lenses have to be USM for it to be a smooth transition?

Lets say you shifted focus to point B as your actor hits his mark, (so you use focus marks and a remote/software to control the motor) but at the end of the shot your actor leans forward a little taking him out of focus; can you then take control of the wheel directly to fine tune the focus after the automatic focus mark has been pulled? (or do you have to switch it from manual to motor/bluetooth controled?)

Also it was said there might be another wheel that controls the iris too; is this for riding the iris only? can the iris be locked and set via the remote unit without another wheel?

Sorry for all the questions but I think I'd need to hear a workflow for using this product to understand what it does fully.

I wasn't supposed to tell you this but Erik informed me that it will come with a lunch box in the shape of the REDONE camera (no production pak - that's extra)
 
Hi Darkline
You are making this too complicated. This wheel just duplicates what a focus puller would use if it were geared to the lens.
1. the remote is wired to the mount, or as I understand it can be wireless through blutooth. No laptop etc is needed
2. Focus speed is set by the speed the asst. turns the "wheel"
3. If the subject leans forward the asst simply moves the wheel slightly to correct the focus.
4. There are no auto. moves to preset. Most assts. would not want that.
5. The iris is locked wherever you stop either the wheel or where you leave off moving it with the buttons.
6. Iris pulls are done just like focus.

The workflow of this product is: attach the wheel to the mount or turn on the power with the not yet seen blutooth accessory. The wheel autosets to the specific lens. Using marks on the wheel the asst turns the wheel to move focus or iris.
If I've misspoken here I hope Eric or others will quickly jump in and correct me so we don't create more confusion!
 
thanks TJ

I have a better understanding but still unsure about a few things.

If the wheel mounts to the lens to control focus, and thats that, what does the remote do? unless....

you say the wheel controls the iris too, so is there a switcher that toggles the wheel between control of iris or focus? is that what the remote does?

finally

"5. The iris is locked wherever you stop either the wheel or where you leave off moving it with the buttons."

Which buttons are you refering too? I thought the main problem on the EOS lenses was that there was no manual control of the Iris on the lens itself.

thanks a lot TJ
