10D reset.....The fix all! Come on now!

It is a well known fact for everybody who is working with
programming, that memory space that is used for holding variables
that you use in a program contains random data at power up. You
therefor have to initialize every variable to a known value. I
wouldn't be surprised if somewhere down in that little 10D computer
there is an uninitialized variable, and in a not to distant future
we see a firmware update from Canon.

That would be my guess as well. Clearing the camera parameters is not, in the PC sense, a reboot (the camera would require at least 2s to restart after that and the parameters clear instantly). The reset can therefore only be doing simple such as setting memory to a known state.

Given that 10D's come with the backup battery fitted it's possible that, out of the box, the memory contains garbage values that produce poor results since they take the camera's software outside of it's normal operating environment ( ).

give it up already.

If you'd read his post or many of the others on the same topic you'd see: BEFORE SOFT, RESET, AFTER LESS SOFT.

It's not an AF issue.

Get over it dude, drop the ego, admit there MIGHT be a firmware problem. I'm done with you.

................ tech support tips for any amount of electronic and commuter gear. The problem you are referring to is a non-responsive “reset” caused by a CPU overload and static retention. Merely shutting down and resetting does not clear this specific incident.

In the Nikon equivalent we are advised to strip all power from the machine, whilst switched on and leave powerless for 90 minutes, this is to clear any catches and reduce static charges that may be causing a “blockage” or erratic behaviour by overloading the CPU or other control chip.

In most cases it works, obviously those with actually faulty parts won’t respond.

Otherwise the advice to power down equipment is not advised, so it is not a recommended procedure unless your machine is having a spasm.

In the case of the E10 and its faulty AF systems, a slow, underpowered processor was cited as the prime culprit as the E10’s CPU had to process information from a wide variety of systems including the massive influx of info from it’s IR targeting systems and the lens motors positioning systems and cross referencing them to align the lens elements. What was happening was the CPU was being overloaded and the lens mechanisms were receiving late data and so a bottleneck, but the design called for instant response, which it is singularly capable of, so it returned and erroneous AF lock signal. The result was that the photographer, seeing the green dot tripped the shutter, but the lens motor controllers were still receiving their data streams and were still physically moving the lens elements into the proper configuration for the chosen zoom and AF co-ordinates at the moment of exposure.

So it is not the first time a CPU or chip overload is known to have caused a problem with soft focus or bad AF. In the case of Olympus many noticed an improvement by turning off IR (reducing the data stream to the CPU) and in the case of the 10D, a static build up in a new machine interfering with its AF abilities is highly probable and that other side functions may not receive all their data streams is also not beyond the bound of probability either.

The fact that these may be cleared up by a power down is not totally unsurprising.

You can shout as long as you want - my camera didn't show any differences after reset and the pictures in http://forums.dpreview.com/forums/read.asp?forum=1019&message=4749319 are not very convincing (the first one looks out-of-focus to me; you can't produce that difference with sharpness settings).

If you would have understood other posts, you would also know why the 10D applies less in-camera processing than other cameras and why the AF of the 10D is perfectly capable of producing defocsued pictures.

I've followed every thread, and I understand perfectly why an image may be out of focus. Primarily, user error (not understaing 7point system, confused by AF point illumination instead of focus lock illumination, etc.). Next, some people have front/back-focus issues on some or all of their lenses, Canon is fixing this for most of them via some calibration routine.

This, however, is something else. It may be focus related, or DSP related; whichever it is, I don't know. But, we've had enough users report success with this that it appears there is certainly something worth investigating here.

It's unfortunate, to me, that apparently you'll never let your ego down enough to admit there MAY be another problem here. You think everyone with a "problem" is an idiot and that because YOU have not PERSONALLY experienced it it CANNOT EXIST!!! Or that this is some sort of pi$$ing match you refuse to give up on. C'mon dude.. There's more to the world than you!

Regardless, time will tell all. Until then, I'm done with you, don't expect any replies from me.

However, I do wish you the best of luck.

Not at all.

So all the other happy 10D users are all idiots, Phil is an idiot too?

Be it, then.
