Re: Making A DIY Anamorphic Lens

UPDATE: I collected the parts for the stand today. The stand is made from 6mm alloy (which I will get anodized next week) with Stainless Steel tube legs. Very sexy if I may so. I am also fabricating a new clamp for the lens which is more robust than the original and will be a lower profile on the finished unit than the current design. It is all looking very good and I will update images soon.

Re: Making A DIY Anamorphic Lens

Mark, I am a newbee to the DIY lens thread. I am now researching trying to decide on my final approach to a 2.35 screen/projection setup. In reading through this thread you mentioned anodizing some of your lens parts. I thought I would mention something that I observed years ago while doing Infrared studies. If you use a typical anodizing process you will find that anodized aluminum becomes a perfect mirror, the closer you get to infrared. Reds in the still visible range are reflected but to a lesser degree. If you want a flat black anodized like surface I recommend you use CHEMGLAZE Z306. This is the only product recommended for optics in space applications. I'm sure it works the same here on the ground.

Thank you for the heads up. I could only use it if it didn't push the production price out to the stratosphere.

The parts that will be anodized are external like the stand clamp and focus ring, so will not affect light performance through the lens.

Re: Making A DIY Anamorphic Lens

After having been MIA for awhile I am back to report what most everyone following this thread can probably guess. I am not making any "REAL" progress with the DIY case. I have worked on it off and on for several weeks and was beginning to doubt my skill when I took the time to catch up on the thread and see that Mark was running into the same issues I was facing. Of course he found solutions to his issues and I gave up......but that sounds really bad so let's say "I have too much going on at work and didn't have the time to resolve the issues I was running into." "There...that makes me feel a bit better"

I have decided to put my focus back on theater construction and just hope this MK5 case ends up in an affordable price range. "Mark, PM me once you know approximately what this case will run" I have these 2 gorgeous lenses here and nothing to put them in

Re: Making A DIY Anamorphic Lens

You're welcome..

There's not so much interest these days in making an anamorphic lens..particularly since the advent of memory zoom that's now available on many projectors..
Are you planning on making a lens?
