I'm planning to send in my lenses and body for calibration. However, they do not open on the weekends so would be asking my colleague (who lives around that area) to drop them off for me.
1. Could there be a problem if someone else (other than myself) drop off the equipment? and what about when picking up?
2. When dropping them off, should I be packing them back into their original boxes? I read it somewhere not to drop off any accessories, perhaps only caps for the body and lens.
3. Other than the original receipts (to proof the warranty), what else would I need to give them?
Any other valuable information before I send them off would be greatly appreciated.
Thanks.
