Awesome!

Just to post different opinion:
I think its a very good/excellent image - BUT I really don't like the post processing on it. (Looks too fake/"overdone HDR" to me.)
Though it seems that different releases of the same software will already have very different processing at times...

Question, anybody have their lens basically quit focusing in AiServo mode..?
Sometimes it will lock, other times I have to press the shutter button numerous times before it will actually correctly focus, even though the point lights up like its locked on. I already know its not the camera as my 70-200 works like it should, refocusing as I pan.
I don't see the same issue while its in "One Shot"...weird
I'm sending it in, hopefully it's not to expensive...well see...

I can't see how AiServo is any different to the lens to any other mode as it is the camera driving the lens. The only thing that could spring to mind is the motor having issues when continuously driving the lens or driving it slowly. E.g. say the camera wants to slowly drive the motor and the small potential is not sufficient to move the lens from rest, that's about it...

Guess Canon is the only party who can answer you there.

Its a single image, not an HDR, the processing is to taste for sure.. At the exposure speed, I could only have gotten the one exposure with the train still on the bridge.

As far as the lens, you can visually see its not in focus, even when the camera/lens tells you it is (the focus point highlights). If I press the shutter a few more times, it will eventually focus. If I pan across a scene, sometimes it will re-focus, other times it wont. My 70-200 convinced me it was the lens and not the camera. I'm thinking its the lens motor going bad, but well see what Canon says...

You can do HDR processing on a single image too -> and get the same look.
You can also do an HDR that looks as if it was a single exposure and looks very natural.

The camera telling you that "not in focus" is "in focus" does not sound right in any way... the camera should be measuring using its AF sensors to make that decision.
And the back/front focussing fixed with micro adjust can't be the same type of problem as that's just an alignment correction. (The camera thinks it has focussed in plane A when it has focussed in plane B slightly offset.)

Nice to see this thread is still going and this lens is still in use, i miss mine, i don't know when i can afford its repair cost without affecting another financial plans.

Keep going, great job from everyone!

That's why I am sending it in...

I suppose the only option really... but it does sound more like a camera issue to me (even though your other lens works). Well, guess it is "wait and see".

Anyway... I haven't posted a photo in a while - unfortunately I don't know what I last posted... Anyway, here is one, I doubt I posted that:

That was my first thought, that it was the camera, and had my other lens acted similarly, it would be the camera going in. I even removed the battery grip to make sure it wasn't causing the issue..(couldn't be THAT lucky of course). Thankfully I only live a few hours away from the repair center so turn around time is thankfully short.

HDR (3 exposures)

It was the AF assembly that had to be replaced...its back now..
