Weird lens flare on photos

| ->> Ok before I send off my camera in fear to NPS I thought I would ask you all if my this is due to a a lens or the mirror in my camera. But I have posted two photos on my member page (#1 & #2) that shows some weird lens flare thing happening with my images. It has only happened a few times with several images, with and without a flash. It seems to only be happening on the outer edges of each frame. Anyone have a diagnosis for me? The camera is a D300 and probably needs a good cleaning if nothing else. It happens with both the lens hood on and off of the lenses. |

| ->> Doesn't look like flare to me.... looks more like bloom. What ISO were these shot at? |

->> Rich, clearly the proper thing is for the seller to offer your money back of to fix the problem with the lens.
I bought a MkIIn from a fellow SS member last Fall, and the first time I pushed the ISO to 1600 I got terrible banding and had to send it into Canon/CPS to be fixed. The seller is a very stand-up guy and I sent him the repair bill (somewhere around $250, IIRC) and he sent me a money order the next day.
Now THAT's what should happen. Good luck with your pursuit of buyer satisfaction. |

| ->> Yeah 400 and 500 ISO on both these photos I thought maybe it was the angle of the sun or something when I was outdoors, I have checked and rechecked the contacts on the body and lens I was using. Maybe it's the lens I will try shooting with an 80-200 later today and see if I get the same results with a zoom. Eric what is a bloom? Maybe it's time for a new mid range lens. The lens that I shot both of these with was an 18-70. |

| ->> I agree with Eric, it doesn't look like flare, which normally comes from a direct light source. It really just looks like your highlights are producing it. I would try cleaning all of your glass and the sensor, to see if that gets rid of the "hazed" look. |

->> Bloom is the phenomenon of adjacent pixels picking up a charge as the targeted pixels are overwhelmed. The electrical signals bleed over to the next pixel. Happens when you crank ISO WAY up and have high contrast (white) subjects blooming into the darker background.
Should not be happening at 400 or 500. More likely a dirty sensor. Put the camera into cleaning mode and shine a BRIGHT light at oblique angles onto the sensor. You should be able to see if there is a haze on the sensor. First thing I would do I give it a good wet cleaning. |
