Zeiss Batis 18mm - weird lens flare

[Andreas]

Hello Batis 18mm owners and wide angle lens experts

Recently I bought this great wide angle lens but was quite disappointed when I checked my first pictures shot with a Sony Alpha 7 II as the lens produced some really weird dots above the sun with aperture 22 (see attached picture). My 10-20mm APS-C wide angle lens on the Sony Alpha 77 produced a much better sun star for a third of the price... ☹️

Did anyone experience the same issue or knows of that issue with the Batis 18mm?

Thanks in advance for your feedback and advice,

Just got feedback from Zeiss support: the issue is not with the Batis lens (!) but seems to be a common issue with the chip of the Sony Alpha 7 I and II. I checked a german forum and there are a couple of other examples of this weird effect.

I will check with the Sony support if there's a possible solution of the issue.

Its light reflecting of the sensor, to the lens, and back again. Its the sensor pattern! And you actually get it on other cameras too.

The solution is to change the angle of the camera until it goes away. A small change is often enough.

Learn & Adapt I guess, basically its what happens when you take photos of a strong light source.
