Even though you are trying to not use "teaser" titles, you are. If you had no idea what this discussion was about and your only hint was "Sankor anamorphic lens"...you still would have NO IDEA what it was about, other than a brand name for an anamorphic lens. You should have titled this one "Problem with focusing anamorphic lens". Please be careful when starting new threads to ensure that your subject is not a teaser title. This is on the rules page.

Registered: Aug 1999 posted 04-02-2004 07:41 AM                     I had trouble with a pair of Kowa lenses. One was razor sharp, and the other had dull defocused areas in the image. I set them up using Brad's set-up tips here at F-T, and things are OK. It doesent take much adjustment to make a big difference on the screen. Good luck. BTW: My lens are set nothing like the adjustment indicators on the lens barrel. One is set at 24' and the other is set at 20'. Both primary lens are the same. I have a feeling that one lens was mis-handled before I got them.  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

The anamorphic is of fairly simple construction but the alinement and squareness of the optical blocks in the unit affect quality of the projected image.....so it is probably a mechanical problem.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-02-2004 08:18 AM                     Zorin, More than likely the front and rear element groups are out of alignment on a rotational basis with each other. These elements have to literally be in perfect alignment with each other to achieve maximum resolution. Sometimes an experienced lens repair technician can re-align them but normally they have to go back to the factory for this to be done correctly. Also, the distance adjustment on an anamorphic lens is not really a focus adjustment, it is an astigmatism adjustment. Few people seem to know this.....
