I´m still wondering how long it will take to switch from my 17-35mm Nikkor to a Red lense. And can I do it in the field, a hotel room or do I have to find a vacuum chamber?
Cheers,
Jochen

Hi,Originally Posted by Josch
Going from PL to Nikon is not an issue at the Nikon lenses are not accurately collimated. With still camera lenses you focus by eye.
You will be able to swop the mount yourself, however don't expect the focus marks to line up, as 1 piece of dust will throw out the alignment.
FWIW I would not rent a camera that the owner swopped mounts himself!

So in other words you don't do it yourself????

Hi,
It depends on the market you're working in. When I first had a Fries Mitchell I used to swop mounts, it's OK for Eye focussing on longer lenses, but forget it if you are working using wide angle lenses. They have very little Depth of Focus.

some of this might be affected by what Gramme has come up with on focus assist ??? if the the lens is not seated correctly then perhaps the focus assist strickly goes by what it see's hitting the sensor ( as in it is based on image sensor is processing) ??? so you might have the lens foucsed to 10 ft and the object is 5 ft but it is in focus ...
unlike film where both the optical view finder and distance to film place has to be EXAC.. the viewfinder could look in focus but the image hitting film plane is out of focus or optical view finder could be off ( out of focus) and the image hitting film place is correct and in film you usually find out when you view your film ...
we'll know at NAB how it works ...

Hi,
That is probably correct, but that won't help you when you're on a dolly and the actor is moving! You have to know which was to turn for 8'!

RED One is a what-you-see-is-what-you-get (WYSIWYG) camera system with a high resolution EVF and LCD (both 720p), with a dedicated focus assist function. The combination of all those elements obviously changes the field workflow dynamics quite a bit. I believe those who are not entirely used to working in a WYSIWYG environment are in for a pleasant surprise and a short learning curve as they re-think their approach to shooting with RED One.
As a both-workflows guy, I'm really looking forward to getting my hands on the RED One system and seeing how the EVF, LCD, and focus assist dance together. Something tells me that they will dance well, and it will take WYSIWYG digital cinema and EFP to a higher level.
NAB should be real fun...

"that won't help you when you're on a dolly and the actor is moving! You have to know which was to turn for 8'!"
but you might be able to work around it ... if your AC has the RED LCD he could then put the marks on follow focus by what is IN focus on the LCD not by the feet on lens barrel ?
if i knew focus on LCD/EFV was correct then i "might" decided that on X day i'm switching to nikon mount and on Y day i'm switching back to PL and we'll have to use LCD/EFV focus over feet marks ?? however at start of a PL lens project i would have a tech make sure PL was seated correctly ...

That´s terribly exciting.
Still - to get back to my original question - would you even consider to change from the 300mm Red to some Nikkors on a set?
That is: All lense characteristics etc. aside. Just the practical process.

Hi Gibby,
When you see you have overshot the focus or turned it the wrong way it's too late, the shot is ruined!
