Oscillation Idea

Dan,
How's the vibration? Could you shoot some video of the device setting on its end with the power on? What are you doing for a macro?

Thanks Dan!

I will shoot and post more footage/stills today.

Did not get the chance to reply earlier. Brett, you are right about back filter (same with the front) but if they are not there, how can this be water proof? Inside is clean (on me) ouside is on you. Once I will finish al tests, I will start taking orders. But first, one must know what is there, right?

Dan,
You are too funny. Looks like the LED is working well!

What kind of price are you looking at? What about the macro?

Dan-
About the filters> Yeah I had the same problem. The solution is just to extend the distance between the GG and the back filter. Try just nother inch or so. This will put any dust that is sure to get on the filter so out of focus that it will never be seen. Makes the adapter worry free otherwise you have to be absolutely perfect every time you remove it otherwise you could be in for a surprise when viewing it after the fact. Unfortunately this also means that your adapter would be about a inch longer and I can tell you were very interested in keeping this as compact as possible. The P+S Technik doesnt have this problem because it creates this needed gap between the outter glass and the GG by the crisscross light path the image takes in the prism. Anyways something easy to fix and consider.

Thanks Brett,
The back cover filter is just a....cover. One could remove it and replace it with a spacer (or take the filter out of the mount) but the waterproof is gone.
Dust has all ways been an issue in this field. But were there is a problem, there is room for solutions.
I had the same thing made with a mirror and a prism attached. I would not do it again. Size, weight, cost, etc. Besides, I had a spec of dust just on the surface of the prism (@0.4mm from the GG! what to do about it other than blow it with compressed air? I did not have in that design the filter behind SLR mount that I have now, that is true.
Anyway, why prism and mirror when you can flip it in post? (and mount two switches on the side of the monitor?)
I am always for new. I see this simple way to achieve the purpose with less trouble.
