Nikon Defocus Control Lenses
 
Hi guys, having finally got total control over my panny-HVX, I am now looking into adding an image adaptor to my arsenal / box of toys. I haven't quite made up my mind which system to go with yet, but in my research, I've come across what are called Nikon Defocus Control lenses.
These seem to be able to adjust the look of Bokeh and whether the focus is sharper infront or behind the actual point of focus (I know I'm not explaining this terribly well, but that's how it makes sense in my brain).
Anyway, has anyone used or thought of using this with an image adaptor?
And to what success?
Thanks in advance
John

Actually DC does not really affect DoF at all. What it does is vary the sperical aberration of the lens to change the character of near and far bokeh. In theory allowing the shooter to choose better bokeh depending on the distance of the out of focus elements in relation to the in focus areas. Sounds like a nice feature of limited everyday use. Who knows. Could be helpful. I don't think DC lenses are produced in many focal lengths though.
