Amen Joe!!


IMHO, MA is a cheap fix for bad QC!!

Whatever happened to buy new Camera, Buy New lens (or use old Good lens), Slap lens on Camera and make sharp Images?? Nobody should have to rely in MA to achieve In Focus Images NOBODY!! Canon, Nikon NOBODY!!

Especially when Canon tells you that you should send them all your gear for them to Calibrate it and Adjust it!! WTF?? That is so plainly ridiculous it's not even funny!! Having to send Like New (Under 6 months old) gear back to the factory in order for them to make it do what it was supposed to do from day one??

When you have a piece of gear (or multiple pieces, like in my case) for under a year and the gear spend more time at CPS than in my hands because it had to be constantly adjusted, it's time to start over from scratch!!

Ask Joe, he knows!!

OK, i compared my 7D to my 1D with 1.06 today with dogs and kids, and the 7D kicked the crap out of my 1D for the keeper rate....... : (

Audible vibrations, especially if they are of a continuous nature are not a good thing in electro-mechanical servo systems. The issue causing vibrations could be (1) a bad overall design and the system is somewhat oscillatory or (2) there is a bad component (maybe too much dead-band making it impossible to drive the servo to a true null) in conjunction with excessive AF system noise.

Now my aiservo unit's going to wear out prematurely!

Where are my waders?

That "something" is your lens ... and yes, guaranteed if you hear buzzing with the shutter button depressed while using a tripod in AI Servo AF mode ... guaranteed.

Hang on to your waders though, you may actually need them someday.

Well I wouldn't call it a buzz.

Regardless why don't you get your hands on one of these, see for yourself exactly what it's doing and then report back. Until then I think I'll keep my waders on!

So...let me guess..there is now a problem with 1.0.6 that causes AI Servo units to wear out?

I wonder if it is screwing with "IS" as well?

+1 This is called Kai Zen in the Japanese production-process; cut out the expensive handling (without loosing quality actually)

If you try holding the focus button down on other Canon 1 series models you get the same focusing noise in AI servo when focused on a stationary target. It is easier to hear on a non-USM lens. I tried it on a 1DMK3 with a Tamron 28-75 which has a noisier focus motor. I think it is the way the 1 series AF (at least in the 3 and 4) works. Forget about and go make some great images!

Got my gear back from canon due to MK4 FF issues.. sent body 300 & 500. Got it back from Jamesburg... Same FF issues.

Sigh...............

"Doctor, it hurts when I do this."

"Don't do that."

Why would anyone put a camera on a tripod and then hold down the shutter button continuously in AI servo mode while focusing on a static object?

The opposite of that would be trying to shoot flying birds in one shot with a burst, that don't seem right does it?

Yes, I once (unintentionally) shot an entire soccer match that way, and no, it wasn't right.

It will be worse than shooting the static object @ AI SERVO mode...

, obviously the sky isn't falling ... and I didn't imply that it was.

Look, it should be obvious to everybody that all (both new and old) lenses are primarily a mechanical device and continuously wear out. If a new camera is designed, optimized, and tested by Canon's engineering staff using only factory calibrated perfect lenses and for some reason chattering and/or oscillations occur when using a few (not all) older lenses then Canon would not be aware of the issue and the Geritol lens population will subsequently wear out at a higher rate.

According to posts I've followed most of the folks (and there are only a few of them) that are having problems with the 1DmkIV and/or 1DmkIV+1.06F/W are having issues with older tried-and-true lenses that have worked well for years. Who knows for sure but perhaps Canon didn't adequately test using older lenses whose elements have a little slop (hysteresis) in their movement; of course this is just speculation on my part.

What is not speculation is the issue of vibrations. If you can hear an out-of-place vibration then you can bet the house that your lens is wearing out at a high rate.

The only lens I own that vibrates is my 28-135; the IS servo is chattering only when I make a dramatic move (i.e. a new composition) from one part of the scene to another. Once the camera settles on the new scene the IS vibration comes to a halt (thank goodness). My IS vibration of my 28-135 has been getting much worse over the last three years and eventually I'll have buy a replacement (sob, sniff, it's my favorite walk-about). I'm truly fortunate that the AF mechanism of the 28-135 has no vibration issues, only the IS mechanism has an issue.

I frequently shoot static objects in AI servo, but I use the * button to AF and don't hold it down...

I use AI Servo for everything and just lift the thumb to stop focusing. With the Mark II and now with the Mark IV I don't see any difference. The Mark III was a different story and I had to use One shot to get reliable focusing on still targets with that one.
