I own a zeiss 55mm e-mount lens and it is absolutely incredible. Never fails to blow people’s minds with its sharpness and depth of field. No comparison with smartphone lenses and easily worth the money. I cherish many photos and moments with that lens. Also, a side note: one of the biggest advantages of a larger sensor like those used in full frame and medium format cameras is the ability to crop in post. Its really about treating photography as an artform - composition matters.
