The 35mm adapter "for the people"

Ahh, alright...well I made the .pdf and left it at work. I'll see if my boss will send it to me thru email tomorrow. I apologize. I sat on my desk thinking what I needed to email myself and couldn't think of it until I came home and read this thread.

Drill press. I guess, if you have no other option around where you live, I suppose I'd drill the holes. I don't know if I can do it for free, because it's not my drill press. I have to bug the guy who has it, and he's pretty cool most of the time. I'm talking like 10-50bux depending on your budget or whatever. Still fairly cheap.

I'll see what I can do about that .pdf tomorrow afternoon. Sorry again, some of you have waited patiently and I haven't been checking back. I'm not looking to make money either. Reason why I made this thread or the adapter.
 
Awesome thanks for all the work you put into this - from looking at the footage its well worth the wait. Thanks again man, you rock!
 
I updated the first page. It should have a working vimeo page.
Let me know if it isn't. I can't tell because my work blocks it.
If it isn't I'll update it when I get home.
 
Could you explain what the "Back Focus Ring" actually is beyond being a "3/8 ring with an outer diamter of 3inches and inner diameter 2.5inches"

How does this ring operate to adjust the backfocus?

Thanks

You tap 3-4 holes into the Back Focus ring it so you can put the set screws in. Your Nikon Lens mount is about an 1.5in long. You move that back and forth to set your lens to infinity lock the screws down.

By this weekend I"ll take pictures of every nook and cranny and have a detail explanation on everything to give you a better idea
 
Thanks. I think I understand now. I thought the ring was some threaded thing that would adjust back and forwards itself, but I think I get it.

Thanks again.
 
Nah, the Black Ring is basically a thick piece of plastic mounted to the Box by bolts. Then the Nikon Lens Mount fits inside. It's to hold the mount plus allowing you to adjust back focus.
 
there will be. I just gotta take pictures. Someone has it now and they're using it. So when they return it, I'll take some pics of all the parts together and how to assemble it. It's not hard to do. Once you get the parts it's like putting lego's together.
 
I'll post pictures tomorrow. Showing how it's assembled.
If I knew how to measure light loss. I'd tell you.
You can check the first page with clips of it under low light conditions.
 
it is quite easy to check for light loss.
If you want a simple way, that isn't scientifically accurate but good enough, expose your camera on a evenly lit wall or anything for that matter, check your exposure meter, add the adapter and see how much you must compensate to recreate the same exposure. Takes all of 2 minutes to do.

Just showing low light isn't a good example of how little light an adapter loses

Bokeh rendition looks great on the night life stuff.
 
Hey papa. Those are two separate camera's.
The night life is the d90.
The other three are labeled DIY 35mm were shot with the 35mm.
 
there are two pdfs for you to d/l if you want. it shows the adapter in detail on how it was built. also a brief quick fix explanation on the motor.
 
Hey Car30, very useful thread!!

One question.. How do you like the quality of that Achromat??

What therad size should I pick?? 62mm ?

Is it sharp, or should I go with the SGpro one???

Thanks!
 
Hey thanks Leteeci...

My opinion..both achromats are top notch. The one I bought was very strong so you can have it fairly close no CA and edge to edge sharpness was great...SG pro, great achrmoat too, but you have to have some distance between the GG and achromat for it to be at it's sharpest. I got the 62mm which is fine for DVX, and HV20...though I have no idea just how it will handle with an HVX..I believe it will hold up just as good.
