Check your newsreader's set up, "Henry", or propagation from your ISP. "Dave" posted a correction/explanation a few minutes after he posted this in error. -- John McWilliams |

My vote is TROLL Odd how people go out of their way to find a problem that won't occur in the real world 99% of the time. |

Talked to my dealer about it yesterday, there's something going on, the lenses are being withheld from the market. But I've had examples of that same lens flare, twice in the last two weeks, with my 24-70 f2.8L, so I have a feeling it's something else, besides or added to, the lens flare problem. -- Skip Middleton http://www.shadowcatcherimagery.com |

Once connected I had a pleasant discussion with "John" who provided me with the following information. Canon has issued a service bulletin for the 24-105 f4 L IS lens. The 24-105 f4 L IS lenses may be subject to significant flare from strong light sources entering the lens at an angle of 37.5 degrees. Parts availability necessary to correct this condition will be available at Canon service centers from Nov.15 onward. During the discussion, John said not all 24-105 lenses have this abnormal flaring condition and tech service advice to callers is mount the lens on a body and test the lens to see if the lens exhibits the flaring anomaly. It would be easy to test the lens to see if the abnormal flare exists. If it exists, it will be readily seen through the view finder if a strong angular light source is used for the test. However, if one wants to be certain their lens is not one that needs repair, then it's best to have the Canon service center check the lens and repair if necessary. I mounted my 24-105 lens on my camera then on a tripod. Looking through the view finder and using a pen (Double AA battery) flashlight, holding the flashlight close to 2 inches (about 5 centimeters) from the lens, I conducted my test. Having a strong light source enter my lens (wide open) at angularities of varying degrees, at times able to see the flashlight bulb, I saw no abnormal flaring as is shown in the examples you posted. Shrug ... Could be I lucked out. |

Don't try reason and research with these guys. They rather have trolls than truths. I admit I should have put a question mark at the end of my sentence, because there was nothing official from Canon posted to the public. But it was meant to be e-mailed to my friend and not here to the group anyway. Sorry again all around to those who got their panties in a wad because I used the term "recall" and have bad punctuation. |

I'm sorry; this post is too factual, of reasonable tone, and devoid of attacks on others or Canon to really be part of this thread..... s Glad your lens passed the test; do you suppose some element or other on the faulty lenses didn't get coated? Also, you spelled flare properly. I was getting used to "flair"! -- John McWilliams |
