HNY (well almost).

HNY back at ya! I hope it brings good luck too (camera-wise).

My wife’s SL2 back-focusses enough to be noticeable compared to the same pic through live view. This with the standard 18-55 lens. I have the opportunity to exchange it or send it in to have it examined by Canon Canada. My question is does anyone have experience having their camera serviced for that reason or if they got a replacement what are the odds of the same problem on the new body. I have read that the tolerances are not that strict when manufactured and recall DPR noting a back focus problem when reviewing the t6i I recall.

If you have the choice, just exchange it (if you're certain it's acting up).

FF/BF issues with bodies are rare. It's almost always the fault of the lens. I have 2 problematic lenses (one FF's, and one BF's). I need to apply autofocus micro-adjustment for both (with my 70D).

If you have a chance, test another lens to be sure (wide-aperture primes will be most telling). Makes sure that the camera isn't set to Auto Mode or all AF points (AF can get really screwy). Always use a single AF point when shooting (anything)!

Best of luck to you!
