I have a new Canon EOS Ti5. I used it at a wedding and got GREAT shots when the subjects were close up. When I took wedding party pictures or pictures where the subjects were further away, I lost crispness and clarity. I could NEVER blow any of these up even to a 5X7….they would look indistinct. SO disappointed! I had the image stabilizer on, and the camera set to auto focus. It was set on the “green A” for all pictures. What am I doing wrong with the group shots or scenic shots that are further away? Any guidance would be so very much appreciated. I thought with autofocus and all these pixels I would be able to make even posters!
