Yup...do as above.
Worth noting...I have problems every so often with my Tamron 180mm losing connection when it's still mounted.....it fit's slightly loose (not bad, but there's a little left to right play). Sometimes it will get to where if I move it with that play it loses contact.....lost precious macro shots due to this.
Fix is easy. I take the lens inside and remove it from the camera. I get a qtip and dip in rubbing alcohol and clean the contacts on the camera body and use the other side of the qtip to clean the contacts on the lens. Re-attach and it works perfectly. I just do this now at first sign of issues....planning to maybe pick up some of those individually wrapped alcohol wipes to keep in my camera bag.
Oh, and I will probably hit 10,000 shots in the next couple of days and mine is still going strong.
