Have the eyecup ordered because I better light shielding - had hoped for - and thus better visual feeling. And does the EC-XT L eyecup also. Much better than the standard eye cup of X-T1. What I would wish: that the rubber would be a little softer (my subjective impression). Therefore, a star deduction
I can only recommend the eyecup.
