I like the container limit too and pairing it with an “outbox” by the door keeps momentum - everything you’re letting go lands there and leaves on your next errand. I also run a quick duplicates pass: pick the best one and the rest auto-donate, no second-guessing. For maybes, I use a “replace-in-one-errand” rule that fits small-town life - if I could replace it on a single trip, it goes - and a photo-for-memory for sentimental stuff. One-in-one-out after that keeps the gains.
Also make sure the lens’ AF/MF switch and the camera body’s AF setting are both on AF and that you’re not accidentally using back‑button focus instead of the shutter half‑press. Try a full settings reset and gently wipe the gold contacts on the lens and camera with a dry microfiber cloth. Then test in good light on a high‑contrast subject and step back a little in case you’re inside the lens’s minimum focus distance.
