Recently I have bought a nikon 35mm f1.8G lens and I realise that a few of my photo is out of focus. My lens was focus on the subject's face but when the picture came out the subject's face is out-of-focus and you can see that the background is clear.
Is my lens having a focusing issue or there's something wrong my technique/setting or camera.
I am still new to photography. I hope to get some advices from you all
Thanks for your input.
p.s. i will try to post a few photo up as example. By the way, 1st photo , was taken at f2.2, iso250, shutter speed 1/250.
And second wedding image is taken at f2.8, iso200 and at 1/125.
