While shooting in Atlantic City, I had problems with my 70 – 200 mm f/2.8 lens. It would not focus at distance when at the shorter focal lengths. Additionally, I had noted that the focus was not spectacularly sharp when the lens was wide open.
So, I am sending it to Tamron for service. I have never sent a lens in for servicing before. So, I do not know what to expect. I sent it via UPS today and they say Tamron should get it on Thursday. Tamron claims a three day turn around for repairs. So, I hope I will have it by next weekend for the Lone Star Rally.
