I recently bought a used Letus Extreme. When you unscrew the Achromats I have found that the lens out of the thread, which is the holding ring can be removed.
The lens can replace it into the ring, and I can complete the screw again to the Letus achromat synonymous, however, the lens moves in it quite easily if I move the adapter back and forth.
I wonder now, does not need to be a solid piece of the achromat? Include Lens and screw ring firmly against one another? Or is this all right?
Please help, if so someone knows.

Normally lenses are fixed, as amended by such a ring with two opposite slots by tightening. Did you this not because fixing ring tight enough?
Antwort von Shen23:
The slots are even noticed me, I just knew not what they serve. (Sorry beginners)
Screws, however, were not it. This probably means but that everything is ok and I only get corresponding screws in order to fix the Lens.
Thank you.

No, you have to own the ring screw in a bit next to the lens no longer wobbles. Go with a watchmaker's screwdriver into a slot or two with the tips of a caliper (interior diameter) in both slots very well.
Antwort von Shen23:
So if I have the ring nut is screwed. But this does not fix the Lens.
If the ring is screwed or not, the lens slips herraus Yet again there.

Aha! yes, then put the bottom of the ring on a black adhesive foil and with a fine nail scissors cut first inside and then outside of or you'll get you a fine O-ring in the right diameter as a kind of washer and lay it on the lens before you see the ring reinschraubst. Man must know what to do. But apart from that it is completely no preference whether the lens can not move or something. It can be yes only act to play a tenth of a millimeter and the optical part.
