Looks like a combo of lens and sensor. The last one looks more like typical lens flare. Were these all shot at f/2.8 as the EXIF indicates, or is that just a default value for a non-coupled lens? Considering there is no starburst type effect around the sun, and the flare has no strong edge definition it kind of does look like these were wide open.
It\'s interesting that you got a ghost reflection of the reflection of the sun in the water. Looking at the ZE/ZF 21\'s block diagram, there are a couple lens surfaces that appear to be perfectly flat, or very close to it, and might be enough to bounce back a weak reflection of the sensor reflection. This was one of the big \'features\' of the previous generation Canon super-teles with a slightly curved front protective element to prevent direct reflection of sensor reflections back into the image path...
I don\'t own the ZE/ZF 21, so can\'t speak from experience. If indeed you were shooting wide open, or close to it, stopping down a fair amount would considerably diminish the size of the flare, though not sure it would affect the reflection. The Canon TS-E 17 is susceptible to flare if a strong specular light source shines directly on the large front element. My experience with it has been that if the situation is unavoidable, it\'s best to stop down a fair amount, such as f/8 or 11, and the flare spots will be small enough to usually be easily spotted out of the image in post.
These are with the ZM21 on the M9:
Both have some flare. The first image it\'s just under the \'er.com\' in the watermark, the second image it\'s at the lower left third in the water. Both shots were stopped down to around f/11. But I don\'t see any indication of a ghost reflection. Do you remember Luka\'s trip to the US when he was in Antelope Canyon and got a really nasty flare with the ZE21? It could be the lens is susceptible to flare in certain suboptimal situations...
