P+S Technics Adapter??
Did I read that there is weirdness going on when using this adapter with Varicam.
Something to do with the spinning glass and the shutter interacting unfavourably.
Why use the Adapter with Varicam as it already looks like film. I understand the depth of field advantage.
Any disasters using this setup?

I just finished a feature using the P+S Tecnics adapter hot on the heals of a shoot using Digiprimes. While the Adapter was not a disaster I do not recommend using it over Digiprimes. The first issue is with sharpness. The spinning groundglass, prisms and whatever air to glass surfaces inside it decreases image sharpness. That may not be a problem for television release but in the film out tests we screened there was a huge loss of sharpness lost through the Adapter. The second problem is that chromatic abberation is increased. The third issue was that with Zeiss Standard Speed lenses there was a noticable “portholing” of a least a stop across the field; especially with the 32mm and 24mm lenses. Super Speed lenses showed no stop changes. Overall the 35mm focal lengths and ability to control depth of field was exaclty like shooting film.
The effect works but doesn’t really improve the image. If you are going to film out you should test it.The negative shutter effect was noticed when we closed the shutter past 90 degrees. It appears as if the groung glass and shutter are in sync rendering the ground glass still. It looked as if the Adapter was not turned on.
Compared to the Digiprimes the image always looked mushy.
