Hi i've looked through the forums but cant see anyone who has the same problem. I bought a canon 60d with a sigma 17-70 f2.8 os lens and canon 50mm mk11 f1.8, when im taking portraits they look great in camera and on the comp, but when i blow them up to 100% they look very soft even slighlty blurred, even on auto focus, as well as manual, diff apertures dont seem to help either, is the camera faulty or the lens, or me? any idea's would be great fully receive, files far to large to upload here, if i resize them they look fine?
any help thanks, John.

Upload a few pics for us to look at.
All sorts of reasons why this is happening, ie, shutter speed to low due to poor light, F stop and shutter speed combination etc?
Are you shooting in low light conditions and what iso were you using?
ps, you should be able to upload images here that will help identify the problem. Also tell us what shutter speed. F stop, iso was used .
You shouldn't look at them at 100% full size.
Try looking at them at 50%. Are they sharp?
ok even at 50% they still not as sharp as from my 450d, will try an upload, i used the idiot mode portrait on these pics in case it was my eysight, still same results though
shutter speed 125, aperture f4, iso 100 shot under the shade of a tree
ok shot at 250, aperture f1.8, an iso 100, shot in same place as previous using canon 50mm f1.8 mk11 lens.
How are you focusing the subject?....Selecting one focus point?....using them all?...Manually focusing?
the second picture has the focus point in the wrong place.... right eye is more out of focus than the left eye, so focus point must be too far forward.... shooting at f1.8 gives you a TINY focal plane, so grate care is required to get it right.
my recomendation is to take some shots of a static item from a tripod in good light. If the results are sharp then its down to technique if not its a camera or lens problem
Which lense are they taken with? Are pictures the same with both lenses?

under second picture.... Canon f1.8 50mm
SORRY, too busy looking at the big picture to see the small print!
I let the camera choose the focus point i set camera in idiot mode in case my eyesight was going . i've never had this prob with my 450d, im gonna go and set up in my little studio and try both on a tripod and hand held, tomorrow , maybe its my technique works fine with 450d not so hot with 60d? just find it weird thanks for all your help so far, John.x
Never let the camera choose its focus point when shooting wide open at f 1.8

Yes i was at a wedding, its why im asking , though i was not the offical photographer, my mate wanted some of his daughters as bridesmaids , did managed to get some decent shots in the end ,
