Thank you for the workaround idea. I'll try it tomorrow morning.

However, does it in general mean that since I'm out of lens fine-tuning range, I would need to take the camera & lens to the service? Is there a way to understand what specifically doesn't work - is it the camera or the lens?

P.S. I guess a good option would be to try another lens on my camera. I have other lenses, but all of them are zoom lenses, so I'm not sure how I can use this method to fine-tune them.

You might want to confirm that your Live View focus was accurate by taking a photo and examining it at 100%.

Did you use AF in Live View, or focus manually? Either way, it is worth confirming that it was accurate.
