- Something that I look forward to see, is how this speedbooster effects bokeh quality. To my taste, in general tele converters have a destructive effect on bokeh quality. I am afraid this won\'t be different for the speedbooster and that the design leaves the bokeh quality of the original lens intact. But the fact that lens design becomes decentered for the position of the aperture (an important factor for bokeh quality) is not very promising. I hope my suspicion is wrong, since the smaller DOF which hopefully comes in a nice bokeh quality, should be one of the selling points of the speedbooster.
....
This will be the big one for me.
I don\'t want to put my Zeiss C/Y 50 1.7 on a NEX with the speedbooster for the ultimate in image quality, I want it for the true 50mm FF perspective and the narrow DOF and associated pop that such a lens provides when paired with a FF sensor.
