I'm shooting some fast moving stuff in the field with limited resources and can't experiment well. When in tight quarters, I use the WA and get a large depth of field. Otherwise, I remove the WA and can use some distance to very quickly setup a nice bokeh from the built-in lens (see attached).

Considering the cost of the lens change, I am wondering how the WA Converter affects bokeh if left it on and I setup with the different perspective. That is, for the roughly equivalent framing, is the bokeh going to be the same?

If the WA adapter is the only part of the equation that changes, in general you will get less bokeh, simply because the focal length is shorter.

You can help compensate for that by backing off as far as you can, zooming in all the way, and then using ND to open up as wide an f-stop as possible.

Yes. The backing off and large aperture is standard operations and how I get the bokeh now. From what you said, it sounds it like if I frame it as close as I would the normal lens, the bokeh will be the same.
