If there is a setting or aperture, everything rotates and moves.

When considering the lenses, it seems to me that PZO AMAR P, PZO EMITAR/S and VEGA-11U will require maintenance or cleaning; with steel ones, everything should be fine. I didn’t wipe or clean the lenses because I’m not very knowledgeable about this.
