Basically I've not been able to produce any ghosts or flare patches. This is taken, also, with Sigma's DG UV filter on the CZ 16-80mm. I have established that this filter, out of all those I've been able to try from my collection, produces no visible relfections and also has the highest quality glass. It's also slim enough to use with the 16-80mm and fits the lenscap unlike my previous B+W slim UV. The combination of this lens, filter and the A77 is what I'm normally using right now and it appears to be rock solid with into the light situations.
For info - ISO 100, no NR (of any kind), strong contrast curve, ACR 6.5 black level set to zero (so I am not crushing any hard to see flare or ghosts). I think I've front focused a touch but that is me not the camera, I did focus in front of the boat to secure a better sharpness on the water, but I thought f/11 would give sufficient depth of field. Wrong; at 24 megapixels, you really can't rely on depth of field at all if you want a sharp pixel view at screen size. In a print, it looks perfect.
