I'm going to try and see if I can implement some of the mechanics in this, in my build.

It's an older Anamorphic lens.

WOW where did you find that gem?

Looks simple enough.

How does it perform with video?

Does it have a case?

What else can you tell us about that?

Mark, I had origninally purchased two of these units. However the guy that sold them to me packed them side by side, wrapped in newspaper. Unfortunately, they did not survive the trip, and completely busted up. This is basically all that survived and the front prisim is chipped. Much to my amazement, it works rather well on my X1, but because of the chip in the corner, I can't use it very well. I'm sorry I don't have a model # or anything. I will be posting more picks of it later.

That is an interesting piece! The prism rotating mechanism looks intreguing as well. Look like a single control (knob) is all that is needed to rotate the prisms?

Hmmm....

MikeP - welcome aboard. I've been a lurker here for a few weeks and like you, I am getting so keen I am just about ready to order my prisms and I don't even own a projector yet ! I'm not the only one like this either. The pure joy of understanding and building something and watching it work is priceless indeed.

A big thanks to all involved from me as well.

I did a quick search this morning on the interent - and came across this company that does coatings for lenses etc. They actually accept visa and mastercard so it seems to me it might not be a king's ransom to get our prisms AR coated. Maybe I'll give them a shout to get a typical cost and post it up here. Worth a try.

Would be cool to find a local place to do the anti-reflective coating work. I emailed the place listed in the above link anyhow.

Neat looking mechanism for the above pictured lens. Looks like an adjustable setup of some kind.

Didn't Sammy (from France) post photos of one of his projects that had both prisms move with one adjustment knob?

I hope you don't mind - here are a couple of shots of the unit!
