Anamorphic standard 16mm

Looks like it's gonna be soft. What lens do you have for the BL? That will make a difference.

 

Ultimately you just have to shoot some tests.

 

Hi Michael Freya

 

Im not to worried about the focus at this moment. What concerns me is the chromatic aberration. If I use this with the BL I would be using Zeiss mark 1 primes.

I'd be worried about getting the diopter mounted straight -- you look pretty "skewed" in the second pic. ;)

 

I don't imagine the CA would go away when mounted on the Zeiss lenses. But you never really know how the optics will combine until you try it.

Michael I heard that HD was more prone to this. I think your right though it needs a test. Has anyone used the 54 iscorama with a 16mm camera?

It's a matter of optics. 3-chip cameras use a prism to split the light into three colors focused at slightly different distances, while film and single-sensor cameras don't. Lens CA can be independent of this, but might be compounded more by one system than another.

Michael these two were taken from the same shot

I think it was just my position in the frame not the Adapters fault!
