Hands down, this is a sharper Image ! ( I say this in general ,like speaking to a crowd ) But it's not the equipment that makes the perfect concept/capture/image ! It's the 12 inches behind the camera that really counts ! YOU!
For instance; Take an hour, two or all day to set up one shot! Not the model! The camera, the lighting and mood of the shot! Then introduce the model to tie the story altogether . Check your shots if they are not clear, sharp images ( and were suppose to be ) do it over.
Focus-- for those do it yourself models, with remote shutter release ! A piece of paper with a heavy black X drawn on it, held by a helper or hung , exactly where the models face will be will help ensure correct focus.
75% ( more ) of images here on DA are blurry ! Grandmothers loves them , Me, not so much! Sorry I get carried away, I just want everyone to do good !
BTW what is your new lens ? 18mm X 55mm ?
