Just curious. Anybody seeing the purple flare issue when using the 7-14 with the latest m43 bodies?
None with my GH3 or GX7. I don't recall noticing it with any of my older Panasonic bodies.
I think it's been reported on the E-M1...which would make sense, it's basically the same sensor as the E-M5.
you can get 'a purple flare' with any camera and any lens....
Photo Owl: No...that's a flare in the lens. Certain M4/3 bodies (the Olympus OM-D E-M5 in particular), exhibit a weird flaring on the SENSOR (basically, I think light accidentally bounces between the sensor and the rear element on the lens, creating this).
This is a unique phenomenon not seen (at least not that I'e heard of) on other systems. While this issue is present with a multitude of lenses, it seems to be the worst with the Panasonic 7-14.
How can it be the same sensor, the EM1 has PDAF.
The purple flare that inflicts both the E-M1 and E-M5 is a result of a weak UV filter on the sensor. It manifests itself as slightly weird purples blobs on the image that are extremely difficult to get rid of in post. It is, by far, most noticeable with the 7-14 f4 Panasonic wide angle zoo. Here is an example...
You can get rid of it in camera by adding a 2A Haze filter which blocks UV light.... with the 7-14 this means adding a back filter but you can add a front filter with other lenses. Here is the same shot with a Haze 2A filter attached
I said "BASICALLY" the same sensor. The E-M1's sensor is - to overly simplify things - an E-M5 sensor retrofitted with PDAF (and they removed the AA filter). The basic architecture is the same, though. Hence why they're both affected.
Why doesn't Olympus fix the weak sensor if it a design problem with the sensor cover ???
Becasue it is not solely the sensor.
I don't think Olympus is too worried about it and I'm not sure they think its a flaw in their sensor. It's only one lens by a competitor which is in the same niche as their own 9-18.
I got some purple splotchies with the 75 the other day. Looking through the photos now. Not toooo bad, the green flares are much worse and noticeable, but they are there. Bummer
