SFD vs Non SFD - Comparison
Here are two shots shot sequentially and only a few seconds apart. One with SFD and one a single shot. I am posting links to full-size minimally compressed JPEGs so as to present each image in the best possible light (pun) :-) The difference in noise is noticeable and the SFD has better detail...
Hopefully this is appropriate. If not, please feel free to delete this comment Rick.

A shot from the driveway a few days ago with the DP1Q:
ex -1, contrast -1' shadow -.8; highlight +2; saturation 0, sharpness -1.0; fill light +.2, Sharpened in PS Lab A100/R.3/T 0 and a slight "S" curve.

ok, still unsure of workflow and whether SFD is actually necessary for my work... especially considering the time element in processing x3i's - and this is on an i7 4770k processor.
i wrote in another thread about being disappointed with the results compared to x3f, but put that down to perhaps some factors tn args pointed out in the following thread:
https://www.dpreview.com/forums/thread/4152203
anyway, before i go off again and do some more test shots - here are some results i've got from my original test shots (available from dropbox files )
i'm still unsure of the best pass through workflow when using spp. you'll notice the differences between the STR (straight through) and the AUTO (auto selected before saving) - in both cases images were saved as 16bit tiff (i use dxo), and converted to jpg via fastsone resizer.
x3f auto
x3f STR
x3i AUTO
x3i STR
the straight through give a more realistic flat view of the subject matter under 5200k studio lights, whereas the auto, in both cases give a much more 'dramatic' feel, which i like and would normally achieve through grading video footage (colour curves, etc), though how some of the artists i work with would react is another matter entirely.
of course, i could try and balance the pics with the chip charts - working in srgb colour space (for print i usually send 16bit tiff with a chart in shot).
any advice, direction, suggestions most welcome.
btw - i posted these via dp gallery, but can't find how to add file name to picture/caption automatically? most annoying.
ALSO - when creating a tiff 16bit from a x3i (using all 7 exposures), i have gotten a very insipid looking output:
x3i - result of straight process through spp

This is a SFD from a few days ago - the wind was nearly non existent, so not much water or cloud movement = SFD weather!
This is the +-0 frame of the 7 SFD frames
This is the 'raw' SFD .tiff before any post processing
This is the final picture, processed in LR to MY liking!
Hope you like it .......

Could it be the rather drastic SPP settings?
I guess you already know that the RGB histogram is a bit high ~30 at left and quite low ~192 at right giving low global contrast.

I took my DP2Q to the Guédelon Medieval "construction site". People there are building a medieval castle with techniques from that area, it's very interesting. Anyway, I brought a tripod and tried some SFD there.
Inside the guards room
Powder used to tint
My experience with SFD :
- I really like the output so far. It allows for subtle result much more than a single X3F file. Could be my lack of skills with SPP, but I always felt Merril or Quattro files are by default very contrasty and don't look "natural" to me. They may look good, but it's not the way it looks in the real world, at least to me. When turning contrast down, the result gets flat and dull. So I end up keeping the contrast or even adding some to get some punch. SFD gives me something more to my liking, I wish the camera could achieve the same result in just one shot. Again, maybe I'm having a placebo effect here and I could get the same result with an X3F file, I'll have to test that.
- Interestingly, auto mode in X3F result in (IMO) way overly contrasted image, but not with X3I, where I actually usually boost contrast. You would think that the auto mode aims for the same result. So my guess is that with X3F files, auto mode may try to hide things like noise in the shadow, hence maybe the very high contrast. Just a guess.
- Opening an X3I image always is in "priority to quality" mode, even if the corresponding check box is unchecked in the settings. I guess that was done on purpose. In fact, you can't even change display mode with X3I files, the button is greyed out.
- Opening an X3I file in SPP doesn't take that long, I would guess about 1 minute, and that's in priority to quality display mode.

I don't see a lot of noise in either the 0 shot or the final SFD which has more contrast and maybe a little sharper. How extreme were the final settings in SPP?

Thanks for the comments. Both you and motorman have good results.

Shot hand held ,saved half size, i think it was 3 images from x3i. I wish there was option in x3i edit to assign alignment points in each image . Even one point per image and limit to twenty pixels difference will make wonders for hand held.With two points it would be possible to compensate for rotation of camera

I was curious whether the SFD feature of the Quattro SD could render a smooth blur of moving water without a density filter. I decided to test at a town nearby that still has some old mill buildings and a fast moving waterfall. I shot with the 18-35mm at 20mm and f16 in order to get as slow a shutter speed as possible along with hopefully sharp details across the frame. Here's the result processed in SPP (full size):
SFD
I was initially pleased with the rendering, then took a closer look at the water -- not good.
Blotches pretty much throughout the entire moving water area
Ever hopeful however, I then unpacked all 7 of the .X3F files and batch processed them out as 16-bit tifs, all sliders at zero except for low sharpening and no chroma / luma adjustments. These I sent to the Nik HDR Effects plugin via Photoshop, wound up with a 32-bit image, dropped that down to 16-bits which automatically called up Adobe Camera Raw to do the final rendering. I slightly sharpened the result with a deconvolution filter, which provided ...

No water problems, but not quite the same "sunny with dark clouds" effect
I'd be curious to know if anyone else has encountered problems with SFD and movement artifacts with possibly other fixes.

Hi Ed --
Was shooting vertically (obvious) and chose the lowest middle of the 9 focus points, which is roughly 1/3 of the way into the scene. I considered switching to the "choose your own spot" mode to go even lower, but decided to see how the standard low focus point worked. Not bad -- the bricks in the closest mill building and the windows above the falls are (to me) acceptably sharp, as is the foliage.

Cool Darrell - I am impressed - I appreciate your getting the details / explanation back to me.
BTW - I know this 20mm (selected out of the 18-35 ART lens).
What (if any other) Sigma SA mount lenses have you used thus far?

good for future updates. I will pass it on. The issue will be how much effort is required and what aligns with what..but thatis for the S/W engineering group.

Streams and waterfalls would be good subjects for posting. I think Kendall mentioned that there may have been some improvement in handling of moving water.
