I have a lot of legacy Minolta MC/MD lens, and consequently I have adapters for my A7ii. All of the adapters - from 3 different manufacturers (Fotasy, Fotiodox and K&F) - are loose. The lens rattles when attached. The K&F Concept adapter is less loose, but it still rattles a little. The adapters I have for other mounts - Konica AR, Contax Yashica, etc, don't rattle, and they're by the same manufacturers. Is anybody else having this problem? Is there a different adapter that doesn't rattle?
