  • 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 :)

Nikon G/DX Lens Mount here!

It's a upgrade for those that want it. Right now we are not selling the mount outright, just to those who have already purchased the original Nikon mount from RED.
 
Thank you, but are you modifying the Nikon mount or not? I send you my Red Nikon mount and 300 bucks; do I then get back my altered Nikon mount or do I get back my original mount and your G/DX mount?

I'm pretty excited about your solution. I just want to make sure I understand.

You will get back an altered Nikon mount only. But keep in mind that Doug is the one who designed and made the Nikon mount for Red. So there should be no worries on your end.
 
You send us your original Nikon mount from RED plus $295 and shipping. We send you a completely different, brand new GDX iris control mount. When we get enough original mounts we will likely use parts from them to make the next batch of GDX mounts.

Here's the complete reply that you get when you email me directly:

To order your Nikon G/DX lens mount for RED, please send $295 plus $25 for shipping (UPS Next Day Air Saver) to the account name:

longvalley@embarqmail.com

via Pay Pal. At the same time, ship your original RED Nikon mount to:

Long Valley Equipment
165 Fairview Ave
Long Valley, NJ 07853

Please BE SURE THAT THE IDENTIFICATION ON THE PAY PAL SHIP TO ADDRESS AND THAT ON THE RED NIKON MOUNT that you send to Long Valley ARE IDENTICAL.

Foreign orders are $295 plus $35 USPS Express Mail International 7 days.

We are only swapping mounts with original RED Nikon mount holders at this time.

If you would rather pay via credit card directly, then send your name, address, and credit card info including expiration and security code via email to:

longvalley@embarqmail.com

Thanks

Interesting. It seems difficult to use in the field for determining the iris setting however.

1. Are you considering some kind of iris wheel that can be marked, like follow focus units have?

2. Does it work with "AF" lenses? I think that's what I have.

3. I was going to get Birger. Is the Birger Nikon mount available yet?

4. Will the Birger have an easy marking system for iris and focus adjustments?

It's very cool, I've been playing with an eval mount since yesterday. The 12-24mm DX is a super cool tool.

That is a lens I would love to know the performance of. How it compares to the RED 18-50 and Nikkor 17-35 2.8, and if possible the Nikkor 14-24 2.8. All good lenses I am sure, but how good?

Anyone tried these out yet?
 
Just sent you a PM

Just sent you a PM

Doug,

I just sent you a PM and an e-mail with a question. Please advise ASAP...:w00t:

Thanks,

Yes, I can make a GDX Nikon mount for the IMS. Can't modify the original Nikon IMS F mount because the rotating locking mechanism would interfere with the iris screw, so have to make a new mount.

Not sure of the cost or delivery time; depends on the number of end users, and right now, I think there is only one end user!

Then I am number two ! Can I send you the standard Nikon IMS Mount ?
 
I have to ask this:

If the DX lenses are designed for DX sensors which are much closer in size than 35MM full frame sensors - then do their focal lengths remains close to their markings? In other words, would a 12MM DX lens perform close to 12MM or get the usual 1.5 or 1.6 crop "magnification" of using still lenses on smaller sensors.

A 12mm lens is a 12mm lens, no matter if it is a lens that covers Super 16, 35, IMAX, whatever. The focal length is the focal length, whether it's a lens designed to cover full frame, DX, 16mm, etc. The difference is in the field of view for a given format size, and whether or not the lens covers the whole format. So an 18mm lens on a full frame still size 35mm camera would have roughly the same field of view as a 12mm lens for the DX format, or for Red. Red and DX are very close.

DX lenses are not made to cover still camera "full frame", but they cover Red One's sensor just fine. The crop you speak of is just a comparison of the field of view difference of the full frame format and the DX format. A 12mm "full frame" lens will have exactly the same field of view on the DX format that a 12mm "DX" lens will have. A 12mm "DX" lens will probably show almost a hard matte circle on a full frame camera, but the geometry of the image will be the same.

My description repeated itself somewhat, but I hope it's understandable.

EDIT: a 12mm IMAX lens would be a real trip, wouldn't it? Especially if it was rectilinear.
 
Just want to say that I had a great experience with Doug. Very quick service from the moment I decided to place the order to taking delivery. Of course my camera is out at RED headquarters at the moment but I can't wait to put some DX lenses on it!

The only thing I would add to hammer home the point that a 14 mm is 14mm is to also say that a 14mm ultraprime or Master prime will be the same as a 14mm still lens or 14mm video lens or 14mm c-mount security camera lens. It doesn't matter what format you shoot or what your lens was designed for - the focal length is the focal length - the only difference would be how big the image circle is so any lens that covers APS-C/DX size or bigger will be fine - anything designed for a smaller sensor like 16mm or 2/3 video will probably vignette or be a circle on the 4k s35 sensor.

You will be very happy. Opens up the lens possibilities dramatically and will burn a major hole in your pocket. :)
 
So let me see if I got this right. I will get the same field of view with a DX lens on a DX camera or the RED camera? I like things consice and straight forward. So a simple bottom line answer for, "Does a 12mm DX lens give you a 12mm field of view?"? No offense to anyone that has a long explanation, I just want something I can staple in my memory so to speak.
 
Since the RED and the DX sensors are almost exactly the same size, whatever you see on the RED you will also see on a DX body.

The effective focal length of the lens (12mm in this case) is the distance from the focusing center of the lens to the sensor.

Stephen your the man. Thanks, thats the black & white answer I was looking for...
 
Fantastic. Have to order another Nikon mount from RED first though, in case we need to shoot that beastly 600mm whilst we wait for the upgraded mount!
