Best Bokeh for a Static adapter

Any static adapters out there that have great bokeh? What is the trick to getting good bokeh if i were to build one. With all this talk about 'neat video' eliminating grain, i'm curious about using a static adapter and then just getting 'neat video' to clean it up. Bokeh being the biggest issue for the look of 35mm, i want to know what makes bokeh. what creates these little details that everybody wants? thanks!
 
I dont think there are any static adapters around now, the G35 is a static but i read somewhere that they were not being made any more.

The movietube is a static adapter, but it is hugely expensive, and im not sure what the bokeh is like.

Wayne Kinney seems to have done a lot of work on bokeh rendition so he will likely be able to tell you what properties the focusing screen needs to get a gooo bokeh...

Never a good idea to deliberately shoot messed up footage and try to clean it up in post. 35mm adapters already softened the image, whatever plug-in you use is going to soften it even more. There's no free lunch. The only static adapter at the moment is the G35, which apparently are supposed to be shipping now, but there hasn't been any report from it.
 
I have a go35. There used to be a lot of talk about it here so if you search you'll find some info. I think the bokeh is great but it can't be stopped down too far. I dunno if its still being made. Kind of a shame because I really think it really has some good things going for it.
 
Bokeh is a function of the 35mm lens you mount on the adapter. Some adapters (like the Redrock Micro) have a lens between the 35mm lens and the ground glass. This can effect the bokeh as you are passing through an additional lens that will add its own light bending effect. If you mount your 35mm lens without any additional glass between it and the GG then you will be fine.

Software like Neat Video corrects grain by comparing luminous and chromo variances over time. The imperfections from a static adapter does not enter the time domain so Neat Video could not remove it. It actually might bring it into sharper contrast.

If you search through this forum you will find a supplier that has a vibrating design that costs a ~$200 to make. It uses a pager motor and focusing screens from Canon cameras. If you are on a budget that's your best bet.

thanks for the input everybody it was very helpful. I still dont understand why grain wouldn't be correctable with a 35mm adapter, i guess i would have to know better how it works.

i just wish they made an adapter that doesn't need rails and is lighter/smaller. in addition provides great bokeh and little light loss. but i suppose i would have heard of it already had someone made one.
 
From what I understand, bokeh is both a function of the 35mm lens and the ground glass. Better light diffusion through the GG results in better light efficiency, but less defined bokeh and vice versa.
