Birger Mount

Hi,

thanks for the links... this is just the adapter that I have been looking for...I have just watched the video test of the kipon and it is very interesting...I see the majority part of tests were made with a full open f-stop...when you start closing the kippon blades - you get a certain amount of vigneting...on some lenses more and some less....is there any way to set the f-stop aperture on the canon lense before putting it on a kipon adapter...for example using a canon 5d camera - setting the f stop for expample f4...unmounting the lense...puting it on a kipon...adn from there on regulate the quantity of the light with kipon, nd filters, shutter speeds, iso and similar....would that kind of approach be possible?
 
Yes, that is what folks have done, but obviously it is an awkward compromise...but it does work until the Birger is available. What folks do is set the aperture, press and hold the aperture preview button, remove the lens which maintains the aperture then mount it on the adapter.

Hello,

I just read your workflow. Is that workflow necessary for this adaptor too?

http://www.amazon.com/Fotodiox-Adapter-Thirds-Olympus-Panasonic/dp/B003EAXT5G/ref=pd_cp_p_1

For my workflow, I set the lens to the lowest f-stop and removed the lens from my canon 7d. I never pressed the preview button on my canon 7D and then removed it. Is that part required for it to keep the correct aperture?

Any guidance would be appreciated. Thanks!

Simon
p.s.
My lenses are:

Canon EF 70 - 300 Lens
Canon EF 28 - 135 Lens
 
The Kipton works best with f2.8 and and below. I tried it on my f4 L lenses and it vignettes very quickly. So if you have fast Canon lenses it will fill the gap until the next player comes to market with electronic control.
 
My understanding is that by just setting an aperture on the camera it does not actually set the aperture in the lens until you take a picture, at least for the instant the image is being taken, though if you are in video mode then it would probably set the aperture. So if in photo mode, then you need to press and hold aperture preview, if in video mode then you can probably just remove the lens at the aperture you desire. Anyone know better?

Interesting. It would be great if someone could confirm this. I will test it out later.

Thanks for your help.

Good day!

That is correct. When using the Kipon adapter, you set the lens all the way open on your dslr, hit the aperture preview button, shut the camera off, then remove the lens, put it on your AF100 with the Kipon adapter.

I believe what you meant to say is " close your lens down to the desired aperture, then hit preview and remove" The lens is already open to it's maximum lens opening, so you would not put it on the dslr to open it up. Just to clarify.

From Birger website

"Sampling to dealers and "friends & family" early March. Ships in volume April 2011. MSRP $700 for the adapter"
 
I like the part about "signing up for additional announcements" as I've signed up twice and still have never received ANY announcements. Good thing I subscribed to this thread long ago! :)
 
I'm sure it would be on here but has anyone heard anything?
i 've been using the kipon mount and its not that bad but would really like to be on birgers friends and family list,

who do i have to marry:)

Well, according to their last correspondence, it is clearly pointed out that they are only a couple of ugly cousin available for marriage and you cannot specify sex preference. Furthermore they warn, just like the adapter, it will be a beta version marriage.
 
Just to double check - in a photo mode on my canon 60D, I would set the aperture I wanted. Then hit the aperture preview button, turn off camera and remove lens, then fit to Gh13 and kipon adapter?

I don't turn the camera off. I just set the aperture, then hit the aperture preview button and unmount the lens, holding the preview button in. It works very well on the 5DmkII and the 7D and I am sure it works great on the 60D or any other EOS.

I am looking forward to the Birger though.
 
I want to vent for a second and I promise I wont go their again but m4/3 adapters with iris control are way to expensive for what they are. I'm not knocking the Birger EOS since what they are doing is really amazing adapting all the electronics of the Canon to work with the AF-100. Its with the other companys that are charging hundreds for plan and simple a mount to use your lenses on the AF-100. Really? $400.00 just to get a Nikon with iris to work? Really? A good lens cost that much and the engineering that goes into a lens is way larger than a mount with two ends. OK I'm done go about your biz.
Ahh. Much better now. Peace.
 
You can buy them for $30 too. I have both a cheapie and a $400 one. I definitely like the more expensive one. They're expensive because there isn't a huge market for them at the moment and they are not mass produced. Look at it like any other lens, they all do the same thing, except that last 20% in better quality is where you pay a premium.
