I've had a T3i for many years now. I picked it up again after a gap of some months and now all the pictures seem to be soft focused. I tried it with different lenses, 50 mm 1.8, 50 mm 1.4, The Canon EF-S 10-18MM f/4.5-5.6. Nothing works! All the pictures are soft focused. I even tried changing to a different memory card. Tried video, manual focus, automatic mode. I upgraded the firmware to that of the November 2016 version. Same result. What could be wrong? Thanks
