Subal GS-180 viewfinder gives a magnified view of the camera viewfinder without distracting changes in angle of view. Optics are superb. Seals with two o-rings for security. This used item looks pretty ratty cosmetically, but the glass is in good shape and optics are equal in use to brand new. The flimsy rubber eyecup supplied by Subal tore, so I repaired and reinforced it with thin strips of rubber. Looks like junk with the added strips and yellowish glue, but it is actually stronger than the original cup and does not collapse when you press it to your mask, as it did when new. GS-180 is currently advertised in USA for $1995 new. I am asking less than one quarter of that for this used one that does the same job as a new one: $495 (plus shipping from Hawaii, USA).
