Hi there,

I have searched the forums etc and found no actual mention of a Still lens adapter for the camera despite lots of talk about Nikon lenses etc - is a stills adapter being offered by red? or another third party? and is this something that fits between the PL and the lens or is it a more elaborate switch?

Many thanks

J.

The Nikon (and other) mount replaces the PL mount on the camera. The question remains as to how easy (or not) it will be to switch mounts.

Have you searched on dvxuser.com ? The red forum there is now closed, but archives are still available. Jim Jannard has clearly stated Red will be making a Nikon mount.

Well, Jim :) posted on subject guaranteeing it would/will be...:

«Very easy. The Trick is to have the base to intermediate mount distance set at the factory and leave enough room for all possible mounts. More details pretty soon.

Is there any interest by red in supporting Olympus or others 4/3 lenses.

I´m going to use my (actually my wife´s) old Nikkor lenses, but also the Red 300mm. Hopefully I dont have to go to a hotel room to switch lenses.

Or do I?

Hi,

As you will need to change mounts, I think you would be well advised to!

The tolerance is idealy +/- 2 microns(Panavision spec) you would be lucky to achieve +/- 5 microns (Arri spec) in your hotel room.

Sorry Stephen, could you elaborate on this?

What would be the difference in accuracy between changing a lens mount in a different environment - would that not be set by the accuracy of the engineering process, or am I missing something?

Cheers!
 
The problem with changing mounts would be dust. Also having the front end of your camera open on set for the amount of time it will take to change a mount is something I would not want to do. Set can get crazy and the risk of dust or other things is not worth it in my opinion. Change the mount in your contoled: studio, shop, house, hotel room or very clean camera truck. Some people have argued this point before that the feel they can change the mount anywhere. I have decided not to argue that point anymore. The way I look at it if people want to chance it fine. It may work fine for a while but sooner or later they will ge burned with a bunch of useless footage and it's things like that that can really have an impact on you career. I have watched as Panavision techs work 15-30 minutes to shim and set a camera mount. It is not a simple process and not something to be taken lightly.

Hi,

As Finner says, dust & dirt. FWIW how tight you make the screws can have an effect.

It's really for camera technicians only, but I don't think that is what people want to hear.

Stephen I fully agree with the first part of your statement. On the second one, of course I can't answer more than your knowledge and experience does but... :D

Otherwise, well, this was already discussed over dvxuser.com...

(and as I already posted)
Jim :) also posted on subject guaranteeing it would/will be...:

Hi,

Yes the have, its called PL mount.

As you already said: it's not what people want to hear! Let's hope Jim is right!
 
Maybe not so much. Jim said this is not finished, yet.

AFAIK, the process only involves 8 screws. It could be something that could take place in a film changing bag.

Hi Brook,

Without a sharpmax or autocollimator you will have no idea if it is in spec or not!

If you are using Nikon lenses, it is not important as they are not accurately collimated in the first place. Using PL mounted lenses and pulling focus wide open is another matter alltogether.

The first time you will realise you have a problem is when you project, it won't be that obvious on a monitor.

FWIW I would not rent a camera from a private person who swops lens mounts himself, however easy it may be to do!

Sure you could change it in a film bag, why not pull the sensor and clean it with windex while you are in there! lol

Sorry Brook, I think you make a lot of great points but pulling apart the front end of the camera in dark bag probably is not one of the best ideas you have had.

I have been lucky enough to of worked with most of the film and HD cameras out there. I feel I have a fairly decent amount of experience with camera mounts and the one thing I can say without any doubt is that changing a lens mount is not something to be taken lightly. Stephen and I do not throw red flags out there every time this is brought up because we want to dampen the spirits of everyone we are just trying to express what a big problem could come about if it is not done 100% perfectly.

I have seen many mounts changed before by full time all they do is fix cameras tech's and it is a very presise slow process. When Jim says it will be "easy" what I take that to mean is we as users should be able to change it ourselves if we are very careful. If the RED camera gives us the users the ability to change the mount in a clean controled environment like a shop, hotel room or clean camera truck in less then 30 minutes that will be so much more "easy" then any other camera on the market right now.

Changeing a mount is a big big deal.
 
Actually, we have what [LINK] Jarred and Jim themselves posted:

«collimnation is not needed everytime you change the mount... a collimnator is just used to adjust your back-focus if something gets knocked out of alignment.»

Succeeding by Jim:

«... which will be pretty hard to do the way this is designed.

«It is completely different... and easier. Things change pretty quickly around here... If anyone is curious, the design process we use is pretty unique. Someday I'll let someone else write a book. :-)
