The Canon EF 17-40 4 L USM wide-angle zoom lens arrived back in my hands today after a non-warranty "repair." Since it apparently shipped from the factory in maladjusted condition, I hesitate to call it a repair and I'm kinda miffed at having to pay for it — decent money, too! Still, it had to be done. My review on Amazon.com will reflect this experience. Report from the Factory Service Center:
We have examined the product according to your request, and, it was found that the adjustment of the part was incorrect the focus did not operate properly from time to time Electrical adjustments were carried out on the part. Checked all, adjusted center/tilt/focus, cleaned all factory specs.
Next I'll test it the same way I did before shipping out and hope it performs to its full potential.
This weekend it looks like we get to work at Mom-In-Law's straightening up after the plumbing project. {sigh} There's a whole lot I'd like to do outside of that but I'm tired.
