7D ghosting?

[tony_fletcher]

<p>I read where some 7Ds had an issue with ghosting, with images taken in burst mode. A recent firmware update was sent to address this issue. Anyway, I was goofing around tonight and I took the following image (to make some friends jealous!) and I see the Guinness neon sign made quite a ghosted image. Is this typical? I've never seen anything like this. Is this lens flare, with a neon sign?<br>

<p>I should add that this was not a burst mode shot!</p>

<p>My guess is lens (or filter) flare.</p>

<p>Was it taken after multiple pints? If so, that could be the reason for seeing double. :-)</p>

<p>Seriously though, I'd guess it's a lens internal reflection, not a sensor issue.</p>

<p>Like others have said, it's your lens causing the flare. It's not a CMOS issue. </p>

<p>That is lens flare. You probably have a multi coated uv filter on.</p>

<p>Mmmmmm.....beer!</p>

<p>dang that beer looks so good.. mmmm beer ;-)</p>

<p>I'm curious which lens you used; as others have said this looks like flare from the sign.</p>

[tony_fletcher]

<p>The lens is the Canon EF-S 17-55 2.8 IS. There is a "sharp cut" UV filter on it.<br>

I always thought-and expected-lens flare to come from the side, across the lens. I'm surprised to see it here, almost in front of the lens?<br>

The beer is good! There's a brewery here in town that lets you brew your own. I made 15 gallons of porter with some friends. The joke of the photo is that they bottled their share and I put mine in a 5 gallon soda keg. I was just rubbing it in!</p>

<p>The filter causes internal reflections from strong light sources. Remove the filter and it's likely the ghosting will go away.</p>

<p>It's a lot easy to make that beer go away than flare and ghosting. I have the 17-55 and it flares without the filter. Amazingly, there are 19elements in that fat little barrel. Light must really struggle to get to the other side! Unfortunately there is a downside to all those elements: flare. Flare isn't bad--it's better than most consumer zooms--but is not as well controlled as the EF 17-40 4L USM or EF 24-105 4L IS USM. Sunsets and bright lights at night result in more ghosting and flare than my L zooms and primes. Still, it's pretty darn good.</p>
