so i took my sisters family photos over the weekend as a favor and also so i can get practice on people other than my kids. while I'm very pleased at how they turned out, i can't seem to understand why they aren't tack sharp. or maybe i'm just being picky after seeing photos from a medium format camera and how crisp photos can be. does this photo look blurry? my sister wants to use it for her christmas card but i am concerned it may come out blurry when printed. i took the photo at ISO 320, f/5, 1/160 ... with my 50mm pancake lens and i was standing probably 8-10 feet from them. thanks for the feedback!
