  • 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 Reservations

Sheltie Guy said:
Also, the new mount is going to feature a Birger submount, so any Birger mount; Nikon, Canon, Four Thirds, PL, whatever Birger makes, will quickly and with proper back focus connect to the submount, making swapping lens mounts a lot easier.

A prior poster brought this up, and I wasn't sure that Erik had actually changed the design in that fashion. But I have to say that that is GREAT news and the smart decision from a business perspective, I should think. I certainly won't hesitate to go Nikon now, knowing that I can easily add Canon functionality in the future should I desire to do so!
 
FOR ECLAIRE:

a14-24mm is always a 14-24mm no matter the sensor or film size

If this is for real, then the Birger lens mount will indeed be a killer!

Thanks for posting the stills, Sheltie!

Of course it is, but I think you missed my use of the term "effective" in describing the zoom range/field of view as it would behave on the RED in comparison to DX-specific lenses. If you want to compare lenses across formats/sensor sizes or mix and match lenses that were designed to support DIFFERENT sensor sizes, you HAVE to include the conversion factor in the discussion to keep things from becoming very confusing or misleading.

Put another way, if I'm going to use the FX 14-24 as one of my lenses, I better have something like an FX 8-14 or DX 12-24 to go with it, else I can forget about getting a wide enough FOV for master shots in the kinds of rooms found in average home interiors.

Well the RED crop factor is about 1.5, which is the same as 35mm cinema cameras have... so your 14mm is about a 21mm or so in SLR 35mm terms. That's getting pretty wide.

But Leon's technically right, a 14 is a 14. The brain cramp is a lot of us are used to full 35mm SLR as a reference point as opposed to movie cameras which shoot the other direction across the film.

eclaire this is incorrect. If you set your DX 12-24 zoom to 14mm it will have the same FOV as the FX 14-24 set to 14mm there is no conversion necessary.

I think when I made the stills I typed the wrong number for the width so the stills I previously posted are a little off. But you get the idea.
 
Sheltie,

Correct me if I'm wrong, but Erik hinted at a multipart design where you could swap the top for Nikon, Canon, PL, etc. but didn't confirm it.

Do you really have confirmation as to this direction or are you going off the same hints the rest of us were drooling over?
 
Fact or fiction?

Fact or fiction?

Since I am testing the Birger pre-prototype I speak with Erik about every week or so. It is not my place to make a company announcement for Birger since I am not affiliated. I'll leave that to Erik. But, unofficially . . .

Are the people responding to me in this thread even reading what I actually posted? I must not be communicating very well.
 
That's funny, I thought the same...lol
By the way, is the Sigma 10-20mm F4-5.6 EX DC HSM AFS compatible?
It is a slow lens, but it can be very useful in daylight and other situations where your lighting can compensate well.

LMAO, let me revoke everything prior and just say this: I think I would still have use for the DX 12-24, even with the FX 14-24. I'm thinking particularly about car interiors.

As for the Sigma, I don't know. I guess you'd have to see if it is listed as AF-S compatible. If it is, I suppose it would work, but Erik or someone with specific knowledge of the AF-S protocols would be the real authority on that question.

BTW, are the Nikon FX 14-24's available on demand now? I know there was quite a wait for the 18-200 VR when it first came out.
 
Didn't get my reservation confirmation yet.

Hey Stephen,

Do you have a sister or niece or whatever named Cindy who attended the UCLA film school in the eighties?
 
Hi Chuck. . .

No sister, cousin, aunt, daughter, mother, or grandmother named Cindy. But I like the name.

:)
