Are any of you using the 16-35 on the S1R??

Curious to know if there any issues?? It as good as on the SL?

Is correction applied in camera, or only in LR or other post processing editor? 

As good as on the S1R. I assume in-camera corrections are as on the SL, although I haven't made twin photos to verify this. There are quite some examples on the S1/S1R image threads.

Used extensively and basically just the same as on the SL except more pixels in the final image. 

Theoretically all the image manipulation coding should be in the RAW files exactly as on the SL ...... although I have noticed minor CA in the periphery which needed correction in LR on some S1R images.

I concur.  The 16-35mm works the same as on the SL, aside from the greater resolution of the S1r.  BTW, the 16-35mm and the 75mm SL F/2 have become my go-to lenses for the S1r, and while I own other SL lenses, as well as the Panasonic 70-200 OIS, the aforementioned are my favorites, the 75mm rarely leaving the S1r's mount.

Tried out the 16-35 on my S1R today, looking for subjects that would use the fine detail of the sensor.  Here's one example

I made a point of shooting wide open and see not problems with sharpness edge to edge.

Or this one, which tries to capture the different living styes in the southern edge of Jerusalem and the northwestern edge of Bethlehem, with a valley and a wall between them.

The 16-35 and the 24-90 SL zooms use software postprocessing to remove barrel distortion and lateral CA in a single transformation, performed once color information is demosaiced and available for every pixel.  In Leica's DNGs there is a standard way to capture the transformation (a function of focal length and perhaps aperture or focus distance) and it can be inspected.  Panasonic's  RW2 files are proprietary, format known only to Panasonic, Adobe and some other experts.  I can open an RW2 file in C1 and see that the same sort of distortion corrections are being done with the 16-35 on my S1R, as are done on an SL but I can't compare the transformation parameters exactly.  Still, I would expect that the information that Leica puts into a DNG would be part of the L-mount specification, rather than held back, since it is not a secret.

In fact the one noticeable example CA is on reflection probably caused by 'ghosting' ..... it's a figure against the sky and probably move slightly during a 1/4sec exposure. The problem is absent in rocks close by which are also silhouetted to some extent, and I have other shots where it is clearly subject movement. 

As you say, there is no reason that Panasonic should have left out lens firmware generated RAW correction info. 

Running the RW2 files through Adobe'd DNG converter should reveal all.....

I'm a bit late to join the conversation about how effective the S1R IBIS is with Leica SL lenses,  There is a Standard Procedure (some sort of standard movement that the stabilizer has to zero out) that allows manufacturers to say they they can add n stops from stabilization.  But Roger Cicala claims that he gave up after several months of effort trying to find a measurement of this aspect that would meet his needs of testing whether a returned camera was still as good as new, or to compare two models. My best results have been with the Olympus E-M1.2 and its 12-100mm lens, shooting at 12 mm, while comfortably seated, arms braced and focused on a shelf of books.  Half of my tries at 4 seconds with this IBIS + OIS combination were sharp at full resolution.  I didn't do as well with the S1R's IBIS and the 16-35 SL (not OIS) lens at 35 mm, but the differences may not matter.  Here are the best of two tries at 1/2 seconds and then at 2 seconds, shown at full resolution.  The area I cropped out was 0.12 of the frame width, or 1.4% of the total pixels.

This is actually pretty impressive, since the FF cameras have to move around a chip four times the size of the Olympus M43 chip.

Varying focal length on the 16-35 @f/4,5.  All are sharp edge to edge and foreground to the trees.
