Mark Williams Posted April 20, 2008 Author Share Posted April 20, 2008 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. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

Has anyone used the 54 iscorama with a 16mm camera? Link to comment Share on other sites More sharing options...
Premium Member Michael Nash Posted April 21, 2008 Premium Member Share Posted April 21, 2008 Michael I heard that HD was more prone to this. 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. Link to comment Share on other sites More sharing options...
