I have a fairly new Tamron 28-75 2.8 Di on my 6D and it seems to have some focusing issues. Not as bad in photo mode but when shooting video, it back focuses. Very strange, it looks okay on the LCD - I even punch in 5x to focus - but the recorded video is back focused. Just to check if it was something with the body, I tried my 85mm and my 70-200 and those look good. Anybody have similar issues? Time to send to Tamron for warranty repair?
