So last week I happily found a lens I've been waiting for a good deal on- the 70-200 f/4 L. I placed the order and it arrived promptly. Popped it on the camera and took a few test shots- and found out that any time you tried to focus at anything closer than 25 feet or so, out of luck. The focusing group got stuck, and wouldn't try to focus.
Popped it into manual focus and working the ring back and forth did eventually free it up, but obviously not thrilled with a lens rated excellent that had this issue, so I sent out an email to KEH asking for either an exchange, refund, or repair. They answered the same day- sent me a prepaid label for shipping, and authorized an exchange for a lens rated EX+ that included the case at no extra charge.
I was bummed about the delay, so I inquired if I could pay extra for faster turnaround and shipping, since my son's little league opening day is Saturday and I wanted to have the lens to use.
KEH responded- they picked up my returned lens from receiving the same day it was delivered (today), and sent out the replacement lens overnight for no charge.
Looking at my order history I'm not a huge customer- I've spent around $1,00 over the last 2 years. Very impressed with how they resolved this issue, and will continue to buy from them in the future.
