new adapter

i like the nice soft glow, and the music setting for the vid.

Wat type of adapter did you use? DIY? bought? And the type static, vibration, spinning type.

Wat the cam u used, and the lens for that vid??

and if DIY how much did it cost for you??

Car3o, I noticed in another thread you mentioned that you did not use a GG for this system, just a 20x achromat and the lens. Can you shed any further light on that? Don't want to know any trade secrets, but I'm very interested in such a system.
 
i'm totally not in the business to keep anything i do a trade secret. it's just as described. i literally took two 8x achromats i ordered from a guy on ebay. used 1.5inch spacer from asian tubes and a nikon mount and placed a lens on the end. there's dof but it's mainly on subjects that are close. there's barely any visible bokeh, nothing great.
 
Can you get a full range of depth of field though, by stopping down? Or is it just limited to close objects as you said? This intrigues me.
 
you know, i never did anything other than that short video
i'll have to do some tests and find out. i'll do some stuff in a
few days and get back to you.

That'd be most appreciated. :D If we could emulate an optical relay system with cheaper parts that sure would be nice. You'd think if this was easily possible the big guys (like Redrock and Brevis) would have tried this before. There's got to be a catch. I know the problems associated with trying to film an aerial image. But Car3o's video certainly indicates that this is in some degree possible. Any other optics junkies want to chime in and rain on the parade? I never thought this was possible either, at least not on the DIY level. Hmmm...... Well done Car3o. Can't wait for the new test.

Edit: Just watched your video again. It seems like you're able to switch focus from foreground to background fairly well. It's hard to tell what the limitations of it are as you're in an enclosed space. But this looks really incredible. So, if this works there would be hardly any light loss, right? Just a tiny bit from the optical elements themselves, but nothing like using a GG. Dang, I gotta try this. If I can get it to work I'll post up my setup. I've got a ton of extension tubes at home. Should be able to fake it. ;)

yeah, what happened was i had a gg and the side of it was cut off a little and i noticed the side a little and i could see an image. so i went inside and took out the gg and did some stuff. there are limitations i'm sure. there is only the light loss the glass and lens have. this clip is a lot brighter, i darkened it in post. i used both the focus on the camera and on the lens...it both needed to be adjusted for certain things. i think the key is the shrink the image down the the 1/3 inch size so it can be projected it off that.
 
Ok, so is the field of view narrowed when using this? That's what I'm hearing should/would happen in such a setup, but I didn't have time last night to experiment with this. On what types of things did you have to adjust the camera focus?
