The only reason for the birger adapter being late must be their lack of funds to complete this project in time. Because if they had the cash to complete it in time they would have sold a unit to all of us instead of loosing to red rock and now maybe even mtf.

They (or Redrock) will never ever sell one to me. I still do not understand the use of electronic lenses on a professional movie camera. Facts and issue oft posted in this forum and this very thread ..confirm to my self ...that I am am correct in my conviction to avoid these lens types.

Many have also posted that they just got on with the job of film making ( and money making) by using existing lenses that actually do the job without a cobble adapter. Hard to go past the logic of that considering the grief.

Tip: Let go of the"precious" Canons and move on.

Shooter, thats fine for you and it's an option. But some people have lot's of canon glass and would like the Birger. I have lot's of Eos glass, so I bought the Redrock and it works great. I have nikkor, contax, Leica, lumix, pentax glass as well. I'll never sell my Eos glass. So to Birger, nevermind the impatience on here from many and just keep working on your adapter. People will buy them. And if you dont like it, take Shooters advice and move forward. I've put maybe 7 different lens makers on the af100. From Eos to PL. Thats the thing about this camera, lots of options out there.
 
I have a Tokina 11-16 EF mount and a great Canon L 70-200 f2.8 w/1.4x that I really want to use with the AF100. I canceled my Birger order and deposit with Rule Camera this morning and plan to order the RR as soon as I return to the States from the Netherlands where I am now shooting. I too am fed up with Erik's Sept 27 promise and following silence. Enough is enough.

Fortunately I also have 3 Nikon lenses: 18-35, 80-200 & 300mm that I have rediscovered with my Voighlander MFT adaptor.

I disagree; I've seen lots of businesses that effectively had all the money in the world to execute their project / product release - but they failed because of poor planning, improper setting of expectations, poor communication, poor project management, and just generally poor execution...
 
Stated another way: Adequate capitalization is a necessary but not sufficient condition for developing and marketing a successful product.

There are a thousand reasons why the Birger project may have gone off the rails, access to funding being but one of them.

I'm going to give them until October 15 or so (when I'm getting paid next) to make a firm announcement, and will purchase the Redrock at that time if there's still no product to order.

Sorry guys, I've been away from this forum for a bit.

I know there's a lot of speculation going on here about the delays, and let me first note that I cannot state all the reasons why. In part because I am not privy to them all and in part because it is not my place to say. But I can tell you that it is not all Erik's or Birger Engineering's fault and that the company also has a "sell no wine before it's time" policy where they wish to make sure that everything functions perfectly before shipping. Agree with that or not, this is the way they choose to do business, and there is some integrity to that. I can tell you that the delays are not particularly due to capitalization issues.

As I understand it, the release of Birger mounts for various cameras are on the order or weeks, not months. As soon as we have a definitive answer from the parties involved then we or someone else will let you know. And yes, i did state "parties" because that's what these things take. There are different variants for different cameras since they each have slight differences in their communication and power capabilities. But I can state that the mount can be used with or without the focus knob and the the unit allows control of iris, focus and IS. Other manufacturers do not.
 
Personally, I've come to accept that the adapter may not come out anytime soon, if ever; hell, in late December it'll be a year since its first announced release. Sure, I was upset once, now I pretty much don't care, and I have enough non-Canon glass, and get enough utility out of dumb Canon adapters, that while fully using what I do have would be nice, it's far from a necessity as I've worked around and past the 'problem'. To me the Birger adapter has become a cautionary tale, a reminder that it's all BS until you have something functional in hand.

Birger? Meh...

One theory I have is a potential patent infringement lawsuit, or threat there of, by Canon. Alas, it is only a theory and I have nothing to base it on. If it is patent infringement, we probably won't see the mount for a long time. The other theory I have is his fabricator in China screwed him.
 
What is it that that statement clarifies?
In fact the whole post from Mitch could be read many ways. The Birger way of communicating is spreading.

He doesn't work for Birger. He is a dealer. There has been doubt on this board as to whether or not the mount will allow control of focus and IS. Some have posted recently that they were not sure if this would be the case. I think my post #611 is specific enough for you to garnish that on your own, but there you go, I spelled it out for you.

Why do you suspect Birger would be infringing Canon? If anything this will help Canon's sales of lenses. If they allowed the mount from Birger to apply the mount for multiple other camera's, i don't see why they would raise their hands over the AF100 mount.

You need to relax hombre, your are wound up tighter than a ministers wife!
I do know who is Mitch. He has sold me a couple of things and I have corresponded with him about Birger.
My main need for clarification would be with “the unit allows control of, ….FOCUS… .If you are not using the focus knob attachment, what is that mean? That it lets you focus manually? Well I hope that was not the hold up.
When he is saying, ‘other manufactures do not” Is he just referring to IS only?

I believe the others only allow for aperture change.

Because certain parts, designs, firmware, and processes may be protected by US patent law. Regardless of whether it helps Canon sell lenses or not, it will not help them sell cameras in the 5D/7D market range. Either way, if your design and or wares are being implemented to make a device, you can sue to stop the production of the device, or negotiate for a piece of the action. Like I said, it is just one theory. If the mount is coming out in a couple of weeks, then it would be unlikely.

It was just a thought, and I should have kept it to myself.

But Birger has already provided mounts that use the Canon EOS lens mount already, for the Red One. In addition, so does a lot of other companies. I'd find it hard to believe Canon would go after Birger and not Red Rock or any other mount. It just doesn't make sense. What would Canon gain out of this? I just don't see any precedence or motivation.

I'd imagine if anything it's a manufacturing issue/concern. Raw materials, boards, soldering, connectors, etc. Most hold ups I have seen have been from sourcing materials.

That's what I was trying to get to. They have an EOS mount for several other cameras.
 
Don't forget that Tamron, Sigma, Cosina, and probably others have reverse engineered Canon's protocols, yet Canon leaves them in peace. Why? Because ultimately it strengthens their position, their ecosystem.
