What do you see without the camcorder? Do you still have vignetting?

How does the image look without the camcorder? Maybe you should move it further away from the GG.

Those are very sharp images!
The 1.4F 50mm lens is the main reason you have such little vignetting. I'd keep the condenser close to the GG if I were you. I use two condensers (and a F1.4 58mm lens)...

Jim, you are too close to just leave it... I think these irregularities in the wax most likely come from different melting or cooling times, or it could be the wax de-mixing. The last one I avoid by...

I can only guess about the G35, but the MovieTube is definitely using microcrystalline wax between two condensers. See the patent page:

Leo, the distance from the back of the lens (without the bayonet) to the GG is 46 mm for the Minolta 58mm.

And you have probably the same focal distance, so I'll do some tests in the coming days to measure the exact distance from the lens to the GG.

So it's the same everywhere, their is no expertise anymore.
Konika/Minolta is a pretty good brand, I shot all my wax tests with practically the same lens. Very fast and very nice DOF distortion.

Leo, the second one is definitely a condenser (from a slide projector?)
The first one could probably be very useful too, perhaps a combination of those two with the GG sandwiched between them.

Should I check the doctor for that?

Besides the technical part, which is great, the film and story have high quality.

It's not nonsense, because your adapter hás less light-loss with the 1.3 lens. The light-loss depends on the lenses used and the GG together. With most telephoto lenses you'd loose much more light. ...
