New VX2100 Sunset Image has sun a hexagon

I just started shooting with my new VX2100 and was wondering if anyone has seen this phenomenon. I took some video of a setting sun over the ocean and the red disk was not round....it was definitely six sided with a star burst effect.......six streams of light emanating from the six sides. All I have on the camera is the original lens and hood and a UV/haze filter.....B&W brand. Any ideas? Is this normal?

Sounds like you're seeing two classic things: (1) an image of the iris at a small f-stop and (2) vertical smear which occurs with very bright point sources of light.

To minimize this be sure to use your ND2 filter which will allow you to open the iris wider. You could also try a faster shutter speed. Careful shooting into the sun as it can damage both your camera and your eyes if you don't use some common sense!

Thanks

Boyb,

The iris makes sense. I will try ND2 and manual to see the effects. I am always a little leary of direct sunlight but it was very low in the sky and was dimmed considerably from ocean haze. A caution to be aware of for sure.

What you see is the standard diffraction pattern which is seen with bright pointsources and high f-numbers with a 6 blade iris cam. Use ND (add external ones if needed) NEVER set for high shutter speeds when shooting the sun: the lens stays open all the time (1/60) even at 1.10000 shutter setting and the CCD can get burned.
