  • 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 :)

How well will the Red viewfinder play together with an eyepiece leveller?
 
Han,han…
so you are hep, my friend.
I wish I knew what that means.
 
Well the camera isn't released, so we don't really know.

The EVF has no need for an eyepiece extension because it's a self-contained unit. You can mount it wherever you need it.

If you insist on using an eyepiece leveler, here's a guess solution:

Mount the EVF on one end of a CF rod. Mount the other end of the rod to a rotational point on the body. Mount the eyepiece leveler to the eyepiece or the eyepiece end of the CF rod. Plug EVF in. Level away.

Hi Brook
I might not have been clear enough, my bad.
I'm talking of the ability to have the viewfinder remaining at a constant angle to the ground while the camera tilt up or down.
Sure you can attach the viewfinder anywhere and that's super cool, but it has more to do with the way it's attached in order not to follow the camera.
I'm not sure what you mean by "a rotational point on the body" though.
yours Emmanuel
 
I'm aware of how eyepiece levelers work, don't worry. What I'm describing should work just like what you have in mind. See the crude picture. If properly engineered, there is no reason that this shouldn't work just as well as an extension eyepiece with a leveler. While I understand that what is pictured is essentially just an eyepiece support, a proper leveler works on the same concepts.
 
Well Brook,
I think your system ought to be very good, and you sure know how those things work, I was more worried about a lack of clarity on my part really.

I just hope the Red team will make it easy for it to work, but it seems very unlikely that they would overlook something like this.

Thank you so much for your explanations.

Yours Emmanuel;)

Brook.. your getting higher and higher on my star list every day :)

What's a CF rod?

An eyepiece leveler is very useful indeed for film style work.
 
CF = Carbon Fibre, if I'm not mistaken...

Not a choice of necessity, but keeps the weight of the rig down.
 
Oh, ok. I thought it was some special type of rod as in order for the leveler to work the rod would have to have some sort of locking solution.
 
I figured CF would match the camera :D

As for a lock, they could exist in the same manner that they do on a standard optical eyepiece system. One on the 90˚ from the camera [aka the "rotational point"] and a telescope lock on the EPL.

Somebody's gonna build and patent this thing and I'm gonna be SOL.

Not sure I get it. Can you post a drawing or something?
 
He's basically describing the same system as was posted earlier (it's a pretty standard VF rig) - look at the triple picture of the Red and SRII systems on page 1...
 
The point marked as "rotational point" in the drawing could have a position lock. This isn't really useful for the EPL function but it's just a nice thing to have. The part that is labeled "EPL" would telescope and lock in place. The shorter it is, the lower the angle of the eyepiece in relationship to the body. The longer it is, the higher. That lock would only to be to set the desired angle - the magic of a proper eyepiece leveler would take care of the rest.
 
I think one of the principles of the Red projects is that they intend to publish a 'bible' of all the mounting point measurements and positions once they are locked down so that third parties can provide the required bits and bobs to hang off the camera. They have their hands full just making a camera.
 
Since the viewfinder is independent of the camera, it might be nice if both arms were telescopic. That way you would not only be able to adjust the height of the eyepiece, but also its distance from the camera.

Hey Brook,

Where did that picture of a Red come from? I don't recall seeing it before.

Cheers,
Damien

It was posted on DVXuser once upon a time if memory serves. I have all the renders [and every other RED image I've ever found on the forums] saved to a folder on my desktop. I'll post them tomorrow [it's almost 3:00AM and I just got back from a shoot... I'm all camera'd out tonight].
