This is an issue and it reduces the image acuity for 3D point cloud modeling for object measurements as well as for the landscape panorama approach.<\/p>\n<p style=\"text-align: justify;\">The against the light shots look very much like\u00a0the\u00a0Samyang\/Rokinon \u00a014mm lens character. The sunstar has light rays that increase in size from the center and these rays cover the full frame of the 1inch sensor when the illumination comes from one of the outer\u00a0edges. It clearly degrades the full image when the lens is stopped down to f.e. f8 but gets better when the lens is driven wide open. There seem to be some diffraction effects at work that are clearly not so great. You can drive the camera to generate sharp sun stars, but as usual here the characteristics of this star make a difference to some of us. \u00a0The Samyang like star is not so well received. The linked flare issue however is much more a problem because it is hard to avoid when you have the sun in your frame and when the lens is stopped down to f8 or f11. For some scenarios a\u00a0lens hood may be useful but its only functional for those shooting scenarios where the sun is not within your FoV.<\/p>\n<p style=\"text-align: justify;\">To be honest I am bit puzzled \u2026 this is the first affordable 1-inch sensor platform with nice resolution and better DR, but \u2013 the flare issue is likely killing some of the potential ideas that you might develop with this machine.
