Hi there,
I,ve got a Zenithstar 80 for a few years now. Lately i noticed the dew shield began to slip. Does anyone know any remedy to keep the dew shield in place or how to retighten it?
I think you can unscrew it and replace the felt inside. Alternatively you can just use an elastic band round the main tube to stop it slipping - I do this with my old camera lenses.
I had the same problem with a Zenithstar 110mm. I unscrewed the dew shield and found the felt friction material had partly come unstuck. I just glued it back in place and everything was fine.
