Strange Flares caused by taking lens with Iscorama 1.5x. Solutions??

Hey guys,

 

This might have come up before, but I seem to be having a strange phenomenon while using any thrid party taking lens with my Iscorama pre 36.  The stock nikkon 2.8 fixed lens that came with the Isco doesn't display these "icicle" like artifacts from flaring. This happens with my Nikkon 50mm  f1.4, and my Helios 58mm 44-2m, and also some weird transparent vignetting happens with the iris blades on both.  I was wondering if anyone knows why this is happening, and or have a possible solution for it.  

 

The picture below is with my Nikkon 50mm f1.4, very simular to the results of the helios.

I had this or reverse vignetting as well. Its just the way the light is bouncing around the surfaces of the lens or in between the two of them. The only way I solved it was getting a custom helios taking lens from Rich here or DSO dog schidt optiks. The way he tested and made me custom rings for the lens was what did it. I dont get this issue anymore at all. Maybe there is a better solution but there is nothing like getting someone who also owns an iscorama to build and test out a proper taking lens for you.

      Hi everyone!
      I wanted to showcase my passion project "The Night Knows No Shore" here on EOSHD. I've been a long time reader of Andrew's blog and it was his footage that inspired me to get an Iscorama a long time ago. 
      After doing tests with it for a while I came up with this idea for a movie. And you can now see the result on youtube: 
       
       
      It's a project made by one single actor and one single crew member (me) with one single focal length (a Canon FD 85mm 1.8) and one single focus anamorphic lens ( Iscorama pre-36). Don't expect much action. It's a slow film with lots of monologues and no real plot. It's about one young man's thoughts on society, religion, art, philosophy, life in general. Have a look. If you don't like all the "pretentious" talking, maybe you like the footage. Let me know what you think. If you have any questions, just ask. Enjoy!
