It does not necessarily have to be you. It can be equipment related such as just a plane crappy lens. What this test does is help us narrow down what the issues could be.
Helping someone with focus is a difficult thing to do via the forums. When Laurin and I do workshops or meet with people we have tried to help we can usually see what the problem is watching them and usually correct it fairly easily. |

Sending my 7D off to Canon next week to get checked out.
Tried all manner of tips and tricks found on the interweb to solve it but still can't get a sharp image out of it.
Will report back once I get it back. |

If you look at an image full size on your monitor, you are going to see tiny flaws.
If you print it and you see problems, then I'd say there's something wrong.
Not discounting that you have a real problem!
But the same type of problems have been reported when people go from a 6MP camera to an 12MP camera. All of a sudden the lenses aren't sharp, the camera isn't working right and it's not as good. Well, true, the appearance may not be, but if you take that giant 18MP image from the 7D and make it 12MP, all of a sudden, it's not as fuzzy? And drop it down to 8MP and hey, it's even sharper.
Just a thought on the whole thing. Going from a 12MP Xsi to a 18MP 7D you do have bigger resolution and any tiny flaws will be enlarged, especially if you aren't using L lenses.
Then again, when it comes back if everything is better, there's something to say about Canon QC and what they are releasing?
I'm a Canon shooter I like how they work, I like the quality and the lenses I have. If I started with Nikon in 1966 I'd be saying the same thing about Nikon. :) |

I went from 6.3 MP to the 7D and there was definitely a "oh no" period where I thought I had a dud. Couldn't get a sharp image no matter what I tried.
Simplified what I was shooting, eliminated variables, focused on techniques and read the threads of others who had problems.
I get sharp (at 100% on the computer screen) images that are awesome printed big.
My camera obviously wasn't a dud (a vicious taskmaster maybe, but not a dud). Can't say that they aren't out there though. |

Yeah, I just can't want to move up to a 7D and have those problems. LOL Still shooting with a 40D and backup is a 20D. I've been buying L lenses.
Another one has been the 5D is a dust magnet. Well yes, 21MP on a full frame sensor, you will see the dust bunnies much better. And bigger?
Yes another problem camera I'd love to own. |

Fully understand that 18MP is going to show up *any* flaws a whole lot better than the older 350D (8MP) I had prior.
I can get away with it for my main shooting topic of motorsport because I'm shooting movement and capturing motion blur.
Having spent the last couple of weeks trying everything I can think of to get a sharp static image and still not getting one I'm at a loss as to what I'm doing wrong, so figured on getting Canon to look at it while it's still under warranty. That way it at least doesn't cost me anything. If it comes back fixed, then good. If not, then I need to send myself away for servicing even though I'm well out of warranty. :-) |

Hope it is the camera then. Shipping on that (body only) is going to be pricey. |

Sure would be. Also not entirely sure where I'd send it. |

Oh I just realized where you are. I see the problem as magnetic inversion, from using the camera in the wrong hemisphere. LOL
Seriously if you don't mind sending it in and there's always the confidence that when it returns, everything will be "perfect" that's not so bad.
And if it was bad and you get a new camera, can't be such a bad deal either, getting it right. |

Simple solution, I'll use it upside down from now on. :-)
I'm sending it in with no expectations either way but at least I'll know on it's return whether the problem is the hardware or the "software". |

Has anyone figured out the tricks of the 7d yet and if so are there any hints you can share ? |
iam having the same problem with a canon 60D. i already sent to canon service twice with my 24-105 and 17-40 and the same. now iam shooting with a 50D...waiting for 5dmkIII. i tried with tripod, test charts, all kind of possibilities and the focus is erratic...the strange thing is if i put the camera on the tripod with a 24-105 lens (is off) focus on something after refocus (same object and distance) , but the distance to the object that is showed in the lens varies...try to explain this. i even bought some focus screen http://www.katzeyeoptics.com/ |

An update. After threatening to send the camera back to Canon, it's decided to start behaving itself and now seems to be producing nice sharp images.
Always amusing how threatening appliances often "fixes" them. :-) |

Not sure.
I did a full reset by pulling out both batteries overnight. Also did a comparison shoot between this and the 550D which showed minimal differences. Figured it might just be the "software" holding the camera so changed a few things about how I shoot.
I suspect a combination of lighting and hardware not working well together (ie, me not getting the best shooting conditions). |

I have a 60D which i use with a 17-40L, a 70-200L and a 50 1.8 and i get consistently sharp images with all, especially when using a tripod. It is very strange the variability that seems to be occurring with the 7D and 60D which both use the same 18Mp sensor.
I had an 8Mp 350D before the 60D and I think it is a challenge getting the much larger 18MP images sharp at 100%. If I downsize to the 8MP equivilent of the 350D, hte 60D images are very sharp, better than i ever got for the 350D
