Problem with my 18-55 kit lens

Hi everyone,

I just picked up a 20d 2 days ago. I brought the kit home, charged the battery, turned it on, and the first one I got had a bad pixel. So I went and exchanged it and got another one, now this one is having a weird problem with the lens. This happens if i take any pics around light's

Example:

What kind of filter have you attached to the lens?

Did You shoot raw and if so what did you use to convert it? There are a couple of threads about the lack of quaility using either EVU or DPP for conversion and results was similar to this one.

No filter was used.

This has also happened to another guy from another forum, all his pics that have lights around em, it happens, he brought it to a camera shop, and they had no idea what was wrong with it.

These wernt shot on raw mode

Some said it could be the sensor, some said the lens, i really have no idea, ive only had it for 2 days..

any other help would be appreciated

On that image, where is the bad pixel?

He'd already swapped out that camera . . . this is the new one.

I'd guess it's the lens. Go to a camera store and put on another lens see if you still get this.

Is the lens clean and free from any film or residue? Was the air clean? Looks too pronounced to be chromatic aberration from the lens - more like atmospheric refraction. In any case, I think it's situational - shooting into bright, intense lights against a dark background. You shouldn't see anything like that in normal shooting.

The rainbows around the lights look like diffraction patterns. The kit lens isn't well known for its optical quality, particularly under rather poor lighting conditions such as this. I'd try a different lens (not a kit lens, try a 50 f1.8 if you can find one).

I have seen this when I had some moisture on the inside of one of my lenses, that condensated onto the glass. It happened a few days after working in a particular hot damp environment, a couple of days in the old hot water cylinder cupboard fixed it (warm and dry!).

However if it is brand new, I would hope you had no moisture in it!

The camera is only 2 days old, and it hasnt been around or near any water or moisture, it is like the 70's all day around here as of right now, so I wouldnt think the temperature/humidity could affect it much

In all cases, this happens when shooting pics and a light can be seen, same happened to someone else, he was in a park, taking pics of the park, there was lamp's all around, they all had little rainbow circles around them all.

Ill probably be heading to bestbuy later to see if i can try out a different 18-55

few other's

Just a guess--but I wonder if the lens got properly coated.

I have no idea what causes this, but if they made a special filter that did the same thing, it would sell.

haha, then trade me a stock 18-55 kit lens, im located in Clearwater :P
