K1 Outdoor Macro Pixel Shift: ISO 8000

Can the K1 Pixel Shift feature be used for outdoor macro work? While we know that the Pixel Shift is not meant to be used during lots of motion, how does it work in mild windy conditions at ISO 8000? I decided to give it a try. This example was with the DFA 100 macro and Pixel Shift motion correction was turned on. The ISO was cranked up high to increase shutter speeds to help deal with the mild wind. Example below. Note the original file is too large to post so it is a small version but looks quite clean for ISO 8000.

Impressive! Out of interest, is this a processed raw file (and, if so, any NR added in post-processing) or straight-out-of-camera JPEG, and what reproduction ratio?

You can always do comparison shots with MC on or off. Or develop the Raws with MC on vs off.

People won't know the limits of Pixel Shift and Motion Correction until they push the limits instead of simply saying "You can't do this or that" and not trying shots.

It was a DNG processed in DCU (a painful program to use) and exported to LR as a TIFF. Not sure of reproduction ratio.

Wow, that is great! Nice colours, DR, no terrible noise, lots of detail, no PS problems

Great shot! I wonder though if the 8000ISO negates the pixel shift improvements? I mean that it would be interesting to compare this PS shot with a lower ISO one without PS.

Because of wind, it would be difficult to shoot at low ISO anyway so difficult to compare.

While it does look good, my guess is that it is only the first frame we are looking at.
Even if you use high iso and keep the shutter speed short, there is a delay between the shots that is quite long and if something moves it has plenty of time to do so between the individual pictures. And as far as I know PS with motion correction will fall back to the pixels from the first frame as soon as any motion is detected, and if this rose moves, the entire rose moves.

Even if it does, it is amazing that you can get such a clean, detailed photo from ISO 8000, even with slight wind. I mean, on some older cameras even ISO 1600 looks terrible. And these shots prove that slight wind is not a problem for PS - great news!

Yep, it's the detail that impresses me. A little post-processing work on my K3 files can usually make ISO 3200 - 6400 look pretty good, but detail is disappearing fast, especially at 6400 and beyond. This K1 shot at ISO 8000 looks *great*

There is nice detail in there...in fact, I would probably lower the NR a bit because it is getting to the point where you have a bit of the plasticky look.
