  1. Turning the focusing ring results in no change of the front element (it does not move forwards or backwards as I turn the ring). Is the lens faulty?
  2. Thanks for the help Drew! I have now been able to do some more extensive testing, and unfortunately try as I may the focusing on the Isco seems to do nothing at all to my image (I'm focusing using the 1:1 punch-in feature on my camera). Only the focus on my taking lens seems to have an effect on my image. I have also tried stopping down my lens to get a deeper depth of field, and then attempting to focus the adapter, but only the focusing ring on my taking lens results in a change in sharpness in the image. Am I doing something incorrectly? Thanks in advance!
  3. I finally managed to pull out the focusing ring out of the locking position to get it to rotate (thanks). However, I'm unfamiliar with these kinds of lenses; is the focusing barrel supposed to rotate 360 degrees continuously without any hard stops? The focusing on the anamorphic seems to have no apparent change in the image compared to my taking lens. Is something wrong?
  4. The lens is identical to this model: http://www.ebay.com/itm/Isco-optic-Cinemascope-2x-Ultra-f-80MM-German-anamorphic-projection-lens-/161416449283?pt=LH_DefaultDomain_0&hash=item25952b8d03 I have tried pushing the locking ring forwards/backwards and it won't budge. Do I need to undo the screws on it in order to push it forwards/backwards? Thanks.
  5. I recently purchased an Isco Ultra Star Anamorphic lens. To my dismay, the focusing ring seems to be locked, and can't rotate forwards or backwards.I don't want to start messing with screws; I'm afraid I'll misalign the elements by doing so. Is there a specific set of screws I should undo? Any help would be very much appreciated. Thank you.
