What is this?
Was at river ang bao to shoot firework. Shoot some test shot at the bridge and notice something interesting.
K10D pentax 18-250mm, 18mm, f9, 30sec  there are a ring of rainbow color 'top' like images on top of the street light.  It happen in all my shots of the bridge at that time. (> 8pm). Is it lens related? or a natural phenomenons? |

Re: What is this?
This looks more like a case of internal reflections rather than lens flare.
Lens flare has the typical polygonal shaped artifacts, bright streaks and an overall reduction in contrast. This comes from light coming at an angle. Looking at the picture, the lens actually is pretty good in control of flare. The funny shapes is likely due to a combination of either your filter (if you had one on) or the lens itself. Your 18-250mm superzoom has 16 elements, so the probability for multiple internal reflections is there. For this reason zooms (with more lens elements) are more susceptible to lens flare and internal reflection than prime lenses.

Re: What is this?
im guessing its because you have a filter on
like what creampuff said,its most prob internal reflections If you dun have a filter on,and there're lights pointing towards your lens it can cause internal reflections as well |

Re: What is this?
Can think of a lot of number for you to use...
Image number, lens zoom range, lens serial number, body serial number, battery serial number... Number of lights on pictures, number of flares in pictures... + whatever numbers you can find in the pictures...  |

Re: What is this?
since there are so many numbers, try for the $10m toto jackpot instead of 4D?
