>>4308807I don't own a dog. The serial number changes the paint and the lens coatings, not the optical design or sharpness. Mine is 7xx,xxx. I'm not even saying I don't like it, just that it's not sharp wide open, and a Zeiss Milvus or a Sigma Art is, and they don't come in an OM mount. Stop getting butthurt over shit you can't change.
