Wow, that's a lot to take in... I'll certainly consider it. And I might return those filters... Thanks for the advice

Wow. Thanks everyone, really great response. Especially brera100 for the background info. I've ordered some cheap 72mm filters to hack together a mount and will be testing shortly, will keep you updated

Hi all, Has anyone come across one of these before, I can't seem to find out anything about this lens? Front markings are ISCO-GÖTTINGEN ISCORAMA - ANAMORPHOT 1.5x - 49 MC. It has the the same front and rear element diameters as a 54. However this one has a 72mm rear mounting thread, and instead of buttons, has the same alignment mechanism as the 42. I haven't been able to test it yet, thinking of hacking together a UV filter mount. In the meantime does anyone have any more info on this lens? Any help would be most appreciated. Thank you!
