| ->> from a Nikon gal....was on a shoot with a friend and every shot she took back focused. Do you think it is the camera or the lens? Not sure if she is a CPS member but is there something she should do before sending both in? |

| ->> Have her reinstall the firmware with a body cap, no lens on the camera. See if the works. |

| ->> Thought one, check for loose screws on the lens and body mounts? |

->> more details, though this never made a difference with my Nikons-she was shooting with the newest Canon flash (I forgot the model-580ex?) on a bracket and an "L" lens and was wondering if the sensor from the flash was tricking the lens?
Clark-how do I tell her to reinstall the firmware? It's an older Canon-the Mark2 I think.
Dave-will pass that info on.
Thank you |

->> Debra, she should be able to get the latest firmware for any Canon model off the USA Canon website. Last time I was there they had the step by step instructions with the download.
I never owned a II, but if memory serves me correctly one of the reasons for the IIn was an AF anomaly with the II. The firmware may fix/help that if it wasn't applied properly or isn't up to date.
The prosumer versions from that era, the D60, 10d, 20d had some pretty awful shutter lag times. This raised the back-focus problem lots when I used to shoot with them. If she is shooting with one of those, it could be just the shutter lag.
Slow focus could also result in the program modes. If she is using Aperture or Shutter preferred, have her try it in manual mode. |

| ->> Debra... honestly, who knows? I have no idea what the shooting conditions were, what her level of experience is, or what other variables are at play. There is no way of telling and consequently, I'd be just guessing if I gave any advice. |

->> Deb,
Get a copy of the last firmware version for the Mark II and put it on a CF card. I believe it is v2.6.1 Put the card in camera and go through the steps on the menu in the firmware section. It is pretty easy.
This is an unofficial fix I discovered years ago. Depending on the camera body, about every 1,800 exposures the AF performance starts to deteriorate on Mark II, and 20 through 40D bodies (all bodies that I've owned at one time or another). It seems reinstalling the firmware restores the camera OS and/or software back to new, much like reinstalling OS on a desktop or laptop (which I do once a year or so) to improve its performance. I usually do this once every other month or before big shoots. In fact, I need to that this week. |

->> I made the assumption she was shooting with a Mark II, a competent shooter like you Deb and knows her way around the camera on assignment. To be clear, she will want to reinstall the firmware for the model camera she is using. She won't be able to install to install 30D firmware on a 40D or 20D.
It is also important to not have a lens on the camera when doing the firmware install. During the installation process, the AF system will optimize itself for the lens that is on on the body at the time. If there is a 50mm on the camera, the AF will be great, but if she puts on another lens, the AF system may not perform that well. |
