Quick question for a Harpia owner (1 Viewer)

[skutchia]

Hello there, could anybody owning a Harpia please just confirm to me whether the grooved metal ring at the objective lens (see photo) is supposed to be stuck to the scope (ie,immovable), or should it be loose enough that it can we swivelled round and round in a circle with one's finger ?
Thanks very much in advance!

I’m a Swarovski user and haven’t used a Harpia but to my eye it looks like a ring into which you could fix a filter, etc.

I too think that's a filter thread on an extendable lens hood.
Btw, if that's salt spray on the objective you should be very careful cleaning it.
After removing the stay-on case put a drop of detergent into a wash basin full of water and lower the objective into it. You can then use a soft tissue under water to clean the objective and subsequently dry off with a fresh tissue.

PS:- Using the lens hood will also provide some protection for the objective lens.

Back to rotation... normally a filter thread is right in front of the objective (a hood just slides out over all that) and no, it shouldn't rotate freely because then one couldn't screw in a filter. Does the ring itself screw back down tight? (that may require a special tool to engage notches in it, or repair service)

No movement on mine

Absolutely silly I know, but both my ATM 65HD and my Kowa 883 have the filter threads in the extendable and rotatable lens hoods.

Just to thank you all of you very much for your comments, particularly Beth. Confirms my suspicion that the thing has broken (in exactly the same place) once again , just a few weeks after a full service ! The last time this blasted ring just dropped out completely, now it's just loose. I'll send it back again - I have had a hard time with this scope...

The few scopes I've paid attention to don't. How does that work? Wouldn't you get glare from an unshaded filter?
