(Updated) The sample was shot with the Panasonic GH3 and Panasonic 14-140mm f/4-5.8 zoom (f/7.1, 95mm, 1/400 sec). Below is a comparison with LR4 mild sharpen (80,0.5,0,0) and additional OptimalSharp V3 standard. Click on the image to view is at 100% pixel view in Lightroom.
We think OptimalSharp V3 made the 14-140 quite a useful zoom and we cannot see any halos.
Here is a second sample. Nikon D800 + 24-120mm f/4 VR @ 105mm (ISO 400, f/8. 1/200 sec). This time we use OptimalSharp V3 Plus at its maximal detail resolving power by removing the mask (click on the image for full view).
Quite amazing what such a wide zoom can produce if we recover all the detail.
