Faq's - P+S Technik pro35 Image Converter MKII User Manual

6. FAQ:
1. Do I have to send my camera to P+S Technik to do some mechanical or elec-
tronic changes before I can use the PRO35 Image Converter?
No, there is no need for any modifi cations, therefore there is no need to send the camera
to us.
2. How does the PRO35 work?
The basic principle: The PRO35 achieves a mechanical and optical adaptation of 35 mm
fi lm lenses to any commercially available 2/3" broadcast video camera (Standard and
High Defi nition) with a Sony B4-Mount.
How does the PRO35 works: The chip size (image fi eld) of your 2/3" - camera is ar-
tifi cially enlarged by an intermediate projection, therefore transferring the 35 mm lens
characteristics (e.g. angle of view and depth of fi eld) to the video camera.
The deciding point is the two stage confi guration: The image, drafted by the fi lm lens is
projected onto an oscillating ground glass, called target. This target is in the same posi-
tion, as the fi lm plane in a 35 mm fi lm camera. For this reason the scale of reproduction,
as well as depth of fi eld and angle of view show the "fi lm like quality", similar to a 35 mm
fi lm camera. In a second step this real image is resized and projected onto the CCD
- video chip. Since this is just a linear squeeze of a two-dimensional image all optical
characteristics like depth of fi eld and angle of view stay the same. This means that the
video chip is not the place of image creation (this is the target!), but of image recording.
3. What do I basically need for a complete PRO35 Image Converter solution?
The PRO35 is delivered by default with a Sony B4-Mount camera sided, a ARRI PL-
Mount lens sided and a light weight support system. Therefore you just need the PRO35
Image Converter for a complete PRO35 solution.
We explicitly recommend the use of a remote switch in order to guarantee an easily op-
erated start and stop of both, camera and Image Converter simultaneous. Correspond-
ing switches are available from P+S Technik, ARRI and other suppliers.
4. What are the additional accessories you offer?
Additional accessories, like different lens mounts, heavy duty support system (19 mm)
and plenty of power supply cables are available.
5. Which cameras work together with the PRO35?
All 2/3" B4-Mount video cameras (Standard Defi nition & High Defi nition) work together
with the PRO35.
6. Which lens mounts are available for the PRO35?
The following lens mounts are available for the PRO35:
* Professional F-Mount for PRO35
* Nikon F-Mount for PRO35
* Canon EF Mount for PRO35
* Canon FD Mount for PRO35
* BNC-R Mount for PRO35
