Confunsion with 5400 and 4300 (NIKON boths)

[alexpg]

Hi All,

I have a 5400 NIKON but I have older user of 4300 NIKON. I use the 5400 for some shots and I see that the pictures of 5400 are little bit more "blured" that the shots of 4300. I dont know this is a error of the 5400 or of me. I take pictures in the same place, with same light, same object but in 4300 is more CLEAR and delimited the contour of the object. Anyone can help me?

Also I see the focus in the object is not perfect in 5400.

Thanks in advance,
Alex
