500mm filter question

More help needed guys. The 500mm that I bought from a guy has a circular polarizing filter in it and I want to remove it. I pulled the filter assembly from the slot and can't figure out how to get the filter out of the assembly. It appears to be factory installed in the gizmo. Thanks

He didn't give you one with just clear glass?

Its a fixed unit and wont come out, he must still have the original.

The optics are designed to have the clear glass in the filter slot, so it is absolutely essential.

There is a clear-glass version that can sandwich gel material (comes with the lens), a version that takes 52mm threaded filters (for ND or colors) and the CPL version. The last two are aftermarket accessories.

And yes, the lens needs to have one installed...

Untill I get some kind of replacement, can I just tape a piece of thin plastic with black electric tape, so light doesnt come in over the slot and use the lens that way, with nothing in the slot.

I see no reasons why you can't do that...

Well, the OP can do that of course, but the lens is unlikely to perform at it's best.

The filter is designed as part of the optics, not having one installed will affect the IQ, don't know by how much as I have never tried it, but effectively you are removing one of the lens elements, so don't expect things to look perfect.
