It moves just a little around infinity and it is same for both MF and AF. Lens has never been dropped or anything. Any suggestions? What to expect if I send it to Canon? Thanks

Something internally broke and its getting caught. You'll need to send it for repairs. EOS 5Dc+BG-E4, 35L, 135 L, 24-70L f2.8, 70-200L f2.8 IS

Jan 12, 2012 18:43 | #3 yes it does move a little bit (not all the way from MFD to infinity). How much you had to spend? I know more about gear than I know about photography

Most likely that is the problem, the focusing track probably has deflected out of shape. Past Equipment | My Personal Gallery

Lucky I got rid of mine before it dies  the f1.4 has ugly bokeh? are you sure you arent referring to the 1.8? Canon 5d mkii | Canon 17-40/4L | Tamron 24-70/2.8 | Canon 85/1.8 | Canon 135/2L

No, the 1.4 has some pretty strange bokeh, highlight halos, etc. This is why people tend toward the Sigma, amongst other reasons like build quality. Past Equipment | My Personal Gallery
