Thank you Joe!
One disadvantage I can see with Vixen 6x21 is that it lacks a clip. And if it had one it's pretty thick and heavy carrying in, for example, a shirt pocket. Actually I am interested in Vixen 4x12(these Vixen 4x12 and 6x16 are available under Opticron brand as well) as a complement. That has not either a clip but is much smaller and lighter.
