[WTB] P&S Optical Viewfinder for SI 2K

[Feyco Feenders]

Hey there,
I'm intersted in buying an optical viewfinder for the SI 2K, build by P&S. Any offers are welcome.

Thank you all.

Best
Feyco

Feyco. Have you enquired with Anna at P+S for a new item or are you after a used item only. P+S may still have the optical finders. Do you intend using the optical finder on a SI2K or are you going to try it on a RED One camera which has been fitted with the P+S IMS-Mount kit and shoot in cropped sensor mode at 2K or 1920x1080. The optical viewfinder is only for B4-Mount HDTV/SDTV lenses normally used on 2/3" three-sensor type cameras which use a prism. It does not work with other lens types. The rear of the viewfinder mounts to IMS only, not PL-Mount. The Epic/Scarlet camera body design makes it impossible to fit the P+S IMS-Mount, therefore it will not be possible to use the optical viewfinder on either Epic or Scarlet cameras.

Hey robert,
yes i asked them if they still have some available, but unfortunetly the don't. But I don't want to use it for the redone or epic and I know that due to the beamsplitter technic its only usable for b4 lenses, right?

You may have already been there already. Maybe post your request at these two addresses at www.dvinfo.net/forum

You are correct about the "beamsplitter technic". The IMS-B4 mount itself suits only 1920 x 1080 sensor crop on the SI2K. Most B4 ENG lenses work fine at 2048 x 1156 but will vignette at wide and again in the region 25mm - 35mm as the lens is zoomed in. The optical viewfinder uses a large piece of optical glass to make the image correct for the SI2K single CMOS sensor. This optical piece allowed opportunity to place a beamsplitter in the optical path. My regret is P+S did not build an optical viewfinder for the PL-Mount. It would not have been easy to do. P+S discovered that people would not pay the real cost of the viewfinder and eventually sold down their inventory at deeply discounted prices. They likely would lose money on a B4-Mount optical viewfinder.
