Replying to @gaberema *this depends on lens type and sensor size* but this is a trusty general rule when you want really sharp videos and images specifically for product/commercial! A lot of cinematographers like to shoot wide open because the aberration resembles analog film and the softness is aesthetically pleasing, especially in narrative productions! #aputure #LikeAMonarch #fyp #zeissprofessionalimaging #lens #lenses
