Really good 35mm DOF Adapter website

**ForwardLooker** · 2007 June 1st, 20:19

Hi,

I built a DOF adapter using the tutorial from this website which I was using with a Panasonic GS400 and it works really well:

http://www.jetsetmodels.info/news.htm

Daniel Has some really good products and some really good free tutorials on his site.

He is now selling a DOF Adapter " I-35HD " and it looks very nice!

I'm waiting for my HV20 to be delivered then I will post some footage.

That has to be the best looking spinning GG adapter i have seen sofar. Way better than the P&S. I am still not sure which I am going to go for, the spinning or vibrating, but I am thinking the Brevis is going to win out for me, but this one looks nice, maybe I will get both.

**Tosh Layton** · 2007 June 2nd, 01:31

oops, after further reading it looks like its a vibrating GG. but it still looks sweet. I am wondering how the quality is compared to the Brevis. I am gonna guess its good.

Theres some new sample footage shot with a HV20 on the site now and its looking good!

But that footage wasnt shot with the I-35HD, right? I mean the I35 is a spinning adapter and the footage was from a nikon d screen so probably one of those other gg holders.

I didnt say that the footage was shot with the I-35, the sample footage on that website is footage made with Daniels products.

The I-35 is actually an oscillating adapter not a spinning one.

As that footage was shot with a Hv20 I thought people might want to see it.

EDIT: The I-35 uses either a Canon Ee-s, Nikon D or Daniels custom wax-gg focusing screen.

It was the VH-72ND vibrating gg-holder

**spiffyman** · 2007 June 20th, 20:42

Wow! That footage just looks amazing.

What would be the best place to learn more something more basic about this type of setup? I read through his site but I'm still fuzzy on the necessary pieces and the theory behind the parts.

Can you say newb?

**Worley** · 2007 June 21st, 02:34

I was fuzzy, too. Some of the instructions are tricky to understand, but it's really easy, so long as you are methodical and don't rush. Most of it does just screw together.

The final device looks complicated, but it isn't. Like all great inventions, it's devilishy simple. My gg-holder and vibrating motor will be delivered shortly, so hopefully by the end of next week I'll have some footage to post.

Hi Guys,

I can help answer questions you have about these DIY adaptors.

So please ask.

**ForwardLooker** · 2007 June 21st, 07:10

Heres some pics of my Adapter.

Front, Back & Side

35mm lens side (Projects image on this side) & HV20 side (Hv20 films this side)

Control Box

This is the adapter made form the tutorial, the only addition is 1 Multi Coated uv filter behind the focusing screen and 1 in front to protect from dirt/dust as they are very delicate. It is important to use Multi Coated uv filters as non Multi Coated can cuase reflections within the adapter.

Feel free to ask questions.

**Worley** · 2007 June 21st, 07:27

First, can we have a side-on view?

Second, how do you know when the focussiing is vibrating at the right speed?

Thank you.

**mik** · 2007 June 21st, 07:49

nice contraption dude

**mik** · 2007 June 21st, 07:50

about the focusing screen noise: it works without moving parts too, just the noise will be static and some don't like that.
it's not a required speed of rotation or vibration, just enough not to see static noise and not to make mechanical noise to be picked up by the mic.

**ForwardLooker** · 2007 June 21st, 07:52

Hey Worley,

I've added a side pic above for ya.

There isnt really a particular speed for the vibrating, I usually keep mine on quite a low vibration unless i get abit of dust on it while filming then i might turn it up to eliminate any signs of it.

The vibration is needed so when you pan around the focusing screen isn't apparent. If you look at static adapter footage when there is alot of panning etc you may notice the grain of the focusing screen.

Ah, now it's all making sense, this vibrating. I wondered what it was all about.

So I guess you could make a focussing screen out of tracing paper... Interesting.

ForwardLooker, turn that motor on full and let's see some real wobble!

**mik** · 2007 June 21st, 09:32

no way it would work with paper
get a slr focusing screen, that's the best thing you can use

**Worley** · 2007 June 21st, 09:45

I say tracing paper because it's not quite transparent, but you can still see through it. I also base this on the photos of the static adapter posted elsewhere on the forum...

Don't worry, I have my EE-S focussing screen waiting for its holder. Any day now, any day... All my bits are just itching to be screwed together.

**spiffyman** · 2007 June 21st, 10:43

So if I understood correctly, the vibration is to keep any dust on the focusing screen from showing up in the video?

I have my dad's old Nikkormat 35mm along with a standard and telephoto lens. Would these lenses be suitable for a project like this? (I can dig them out and get some specs if needed). Besides that I just need to buy the kit on the web site you posted and screw it all together?

I'm assuming you use the manual focus on the HV20 or do you use the focus on the 35mm lens?

Thanks for all your help!

**Worley** · 2007 June 21st, 11:21

I think you need to focus the HV20 on the adapter's focussing screen, and use the focus control on the Nikon/Canon/Whatever lenses.

**tkmslee** · 2007 June 21st, 11:44

What are you guys using to screw it onto the camera? Most macro lenses don't have a way to attach it to the tubes. I am going crazy trying to get mine all nicely mounted, and still look professional (ie not duct tape jobs).

It depends on what size extension tube you end up getting as there are 2 floating around. 1 has a inner diameter of 54.4mm and the other 55.3mm, If you get the 1 with with 55.3mm then the thread is 58mm and you can just buy a stepping ring that is 43mm > 58mm.
If you end up with the 54.4mm there isnt a confirmed thread size for this but I was told its more than likely a 55mm. so i'm waitting for a stepping ring at the moment (43mm>55mm) and I will let everyone know if that is correct.
As I have the the tube with 54.4mm innner diameter I originaly connected this adaptor using , 43mm > 52mm step ring, 52mm coupler and a nikon br3 but I found that I couldnt focus the hv20 after zooming in on the focusing screen.

Nikon Br-3

**ForwardLooker** · 2007 June 22nd, 06:31

Heres some test test footage, its not very interesting but it does show the quality you can acheive. I also forgot to turn on my vibration and i didnt clean my lens so u can see the effects of non vibration. i was holding the adapter up to the hv20 so that was my main concern. As soon as I can mount the adapter properly i will post somthin worth watching.

I made a video tutorial about the basic principle and building a vibrating dof adapter. But after I posted here the link to my homepage for the free download it was removed automatically.
Why?
