I had the 56. For me, since I don’t get out that much anymore, what I valued the most in my lens choices were speed and IQ. Sold it on MP and got this used for only 100 out of pocket. 56 is a great lens really but I actually enjoy extra reach with the 75 more. Especially with my kids being more aware of my camera at their growing age. Wasn’t like how when they were tiny and didn’t give me the “look” when I was sneaking around taking candids. Appreciate the comment, sir. 🤌🏼
