  • blurry 50mm portraits?!?!

    So i bought a 50mm f1.8 prime lens to take better family portraits. I have been messing around with the settings and taking shot after shot to try to get THE beautiful shot, but of course I end up with shots that are too blurry. I've been reading so many articles online that I get the gist of what I'm supposed to do, but I just can't get there.

    So I wanted to see if you all could take a quick look-see and tell me where I am missing the mark. Thank you so much in advance.

    You might be to close to the subject.

      oh my. I never thought about that. I always try to get close to get pictures that focus on the subject and not the clutter around the subject. So you're suggesting pulling back to get a sharper image and then crop in post-processing?

        I think the 50mm 1.8 has a minimum focusing distance of at least 18 inches, if not more.

          Yes. Give it a try, . Not much though, you dont look that far off. Maybe a matter of inches.

                  You're also shooting at f/1.8: The DoF is so shallow, especially up close, that any movement will move the subject out of focus.

                    ^^^this + ISO 6400 will compromise clarity, especially when pulled in and viewed at 100% Also you should be sure you are doing portraits like this in One Shot mode where focus has to lock in before you can take the picture..in Servo modes, it doesn't have to lock in focus in order to take the shot.

                      If you're using autofocus, you're not too close to the subject. If you were too close, the lens would focus-hunt rather than lock focus and the shutter wouldn't fire. (Ah, right -- if it's in one-shot AF mode, like autofocus points out, appropriately.)

                      It is close enough, though, that your depth of field is really small. (ISO 6400 doesn't help with sharpness, though that picture looks legitimately out-of-focus to me.) If your head or the subject move just a bit, it'll be knocked out of focus. I also think that the T2i/T3i autofocus is not as accurate in such low light.

                      I honestly fixed this with the much-maligned spray-and-pray approach. With 3-shot bursts and many attempts, one of them will actually be in focus!

                      Your life would be much simpler, though, if you could gain 2 stops of light. f/2.8 and ISO 3200 on that camera and lens is, IMO, enormously better than f/1.8 and 6400.
