Any relation to the solution to the Panasonic 7-14mm & OMD EM5 purple flare problem you figured out?

Not such a bad guess tex. As a matter of fact, the explanation/solution I have now come across is at least in part a by-product of our go-around with "Mr. Fish" in this thread


a little while ago although the credit for making the observation that put me on the right track is, as that post reveals, certainly not his.

Ironically, this phenomenon (residual PF that in some important ways behaves like LaCA rather than LoCA) is one that I observed, and was puzzled by, already before the problem with purple flare with the 7-14 on the E-M5 surfaced. And in both cases, I was on the right track early on but incorrectly rejected the hypothesis due to not having/using quite the right equipment, as you can see here:


Looking forward to the answer. I fly out on vacation Sunday night, so tomorrow morning is my last chance to buy gear before I leave

So hurry up to that well-supplied camera store I am sure you have around the corner and ask them to replace the UV/IR-cut filter on the sensor on your E-M5 with its counterpart from the GH3 (which I think has quite the right size to fit ). If, against all odds, that would fail, just ask them to pick up one of those Wratten 2A or Wratten 2E gels I am sure they have laying around in a drawer somewhere since the last time someone asked about them 20 or so years ago. Then pick up some thin double-adhesive from the hardware store next door and you are all set to go.  

Dunno what the camera shops in Sri Lanka are like, but I'm guessing they're not that great.

Could conceivably be that they are not quite as well equipped as those in Vienna, but this is easy-peasy stuff so surely no problem.

Personally, I might have better luck. Flying out to LA on Wednesday for a trip to the Sierras together with my wife, our son, and our daughter-in-law. Possibly, I'll have to time to pass by Samy's and pick up one of those Wratten 2Es I see they have in stock. Good price too. Only 24.59 for a 3x3 sheet.
