Yes I'm afraid I have another adaptor.

Snodart......I'm not using a condenser......just the lens projected right onto the aol screen. The light spreads well on the screen so there's no problem with vignetting or hotspots.

Wow, that's great. I thought you were using a condenser. Thanks
 
I am seeing a lot of Nikon focusing screens on eBay but none are type D. I was was wondering if I was to use another type of screen like C, B, or a U what the difference if any would be on the adaptor?

Many of the other focusing screens have the focus guides (I think that is what they are called), which would end up in your footage. See this page for examples of what I mean:

As I understand, the D screen is no longer made, so finding one is tuff. I lucked out and found one a few moths ago at Sammy's Camera in LA. It will be a needle in a hay stack search, but you never know... you still might find one. I am starting to look into the other options now for when the day comes that I scratch my D screen.

EDIT: BTW ovjamaica, your footage looks great. You are using the D screen correct? Your footage has a look that is very similar to my static GG version (D screen also). Where did you get your Nikon F mount from? I have been scanning ebay for something to pull an F mount off of, but can't seem to find anything under $50. Also, is $100++ a pretty standard price for a nikon 50mm 1.4 lens? Thanks

Thanks for the kind words snodart. I built my adapter basically out of two of these. The tubes have a Nikon F mount as part of the set. I used two of them because I needed the individual extension pieces for the length I needed. I have the Nikon D screen mounted at the end of the first tube (set of three pieces as shown and the F mount) and then a few more extension pieces between the D screen and the achromatic lens. I had to JB weld a UV filter to the extension tube in order to have it thread into the step down ring I am using. The tube itself uses really weird threads. It's just slightly bigger than a 55mm UV filter. I think a 56mm would be perfect but nobody makes anything that size. Anyway, I'll post photos and plans up sometime, but that's the basic idea. The tubes are cheap and work well.

$100 for a Nikon 50mm f/1.4? Sounds a bit high, but not bad. I got my Nikon 50mm f/1.8 for $35. So, look around. My 1.8 seems to work just fine.

Thanks marlenedegrood, I just wanted to increase my chances before I ordered. I can't wait to try the plastic out.

Thanks for the info. I'd love to see some pics. Building these things is often like putting together a complicated puzzle. Sounds like you found a great solution.

As for the Nikon lens, I think that the 1.4 is considered some sort of a gem or something. I still can't find a 1.4 for under $100. The 1.8's are, as you said, down in the $30-$40 range. You know, I have been pretty adamant about getting a 1.4 lens, but I hardly ever have my canon lens set to 1.4 on my adapter since the DOF is so small. Maybe I will just get a 1.8.

Thanks snodart, that cleared it up for me. Thanks! :)
 
Yes, that is exactly right maze. It is an achromatic lens, meaning it changes the way light passes through it.
 
Is there any change in the construction because of the canon 250D? Because its just 52mm instead of 58mm.

Thanks
 
You can find 250D's that are 58mm in diameter. If not then you'd need to alter the design to allow for the 52mm achromat. Are you building the original design with the pipes from Home Depot and such? I ask because many of us have taken this in different directions.
 
after visiting a film studio in prague, the animation company ACE gave me a take home 3D with glasses demo in a dvd case. And the dvd case happens to be the same as the aol, or at least i think. He gave it to me, and as i thanked him, it wasmotly because of the fact that i noticed how opaque it is. Slightly grainy, and clean as a babys bum.

Now the question is, what is the best way to cut a little circle out of it to place it between my two uv filters?
 
There is a best way for everything right? It usually consists of buying an expensive tool, a template, and practicing a bit first.

Me, I just use whatever tool I have or can borrow, then fly by the seat of my pants with it.

Does the case have any markings or indication of the manufacturer? That would be great. The way I did mine was just measure a circle of the right circumference, draw around that with a Sharpie and then cut it out with scissors. Just touch the plastic around it, never the plastic that will be the screen.
 
im on my 3rd generation adapter.. now using the acromatic diopter.. unfortunatly my little sample of aol dvd case marlene sent me got glue on it and is ruined.. and i have no idea where to get another case... in the mean time i went to office max and found a notebook thing that has pages that work.. (if i put 2 or 3 together).. but heres the problem.. i still cant get this to work.. with the new diopter.. i cant get in close enough.. and i just cant focus well.. any help? ps.. does anyone have an aol case i can buy?? im desperate.. i need this adapter to be up and running again asap
