You’re definitely right. I didn’t mean to imply my “full wide zoom/macro” trick is the way I normally shoot. Especially on interviews, I’m always looking for that focal length/f stop combo that gives me the most control over the background sharpness. It’s just that nothing I’ve seen out of the NX5U is any more dramatic than my old PD-150 or PD-170. Did they have a 6 blade iris? I don’t know.
I just don’t see the 6 blade iris that Sony specifically refers to in its marketing doing anything different than other 1/3″ chip cameras. It’s interesting to me that Sony would highlite it like it is something unique to the NX5U.
For example, the marketing hype for the Canon XA10 (and a number of its other camcorders) says: “In contrast to a typical 6-blade iris, the XA10’s 8-blade iris captures extraordinarily smooth out-of-focus ‘bokeh’ for a more attractive image effect. The additional blades also reduce diffraction of light passing through the iris, allowing for the use of smaller apertures while maintaining image quality.”
