Snod35 DIY adapter info
 
Hey all,

Just wanted to post a link to some info as to how I built the Snod35 35mm adapter:
http://snodart.com/hbe_snod35_v1.php

The short films Cache, After Class, and The Seeing were all shot with the Snod35:

Also, I made this depth of field tutorial for a DIY adapter DVD/kit that didn't end up working out. You can view the tutorial here:

If you want to watch the full version of the tutorial, please download it by saving it to you computer (to save my bandwidth). Otherwise the tutorial can be viewed in sections. Thanks.

Justin,

I just ordered a few parts from your diy list. I like your solution for adjustable focal plane for the focusing screen. Right now i have an EOS mount extension tube set, but would like to convert to Nikon F, and having it glued instead would be a pain to change. Good thinking!

After reading your experiments with motors, i decided to do a little more search before buying one. Do you have any experience with this model http://www.hobbyengineering.com/H3425.html ? It's mentioned on Daniel's DIY, another great starting point for novice tinkerers. http://www.jetsetmodels.info/pics/basic_35mm_dof.pdf

Anyway,
just wanted to say thanks.

Very good tutorial. Nice work. I have also done almost the same thing with my 35 adapter.

Justin Snodgrass May 3rd, 2007 09:45 PM

Hi Yev, that motor is a solarbotics 12mm motor. I have tested it several times and with the design of the Snod35 it just didn't stand up to the Sanko motor. As you mentioned, Daniel uses the motor with several of his designs. From what he has told me, he is getting a good circular vibration pattern with the motor. The Sanko motor is just such a great motor that the 10 or so other motors that I tried just didn't compare.

I am currently working on a design that uses thin metal wire instead of the nylon threaded rod. I feel like I have tried just about everything to get the smaller motors to perform well, but I suppose there is still hope. It kills me that the Sanko motor is no longer around.

Thanks for the post Igor. DIY 35mm adapters can be addicting.

I've got a macro adaptor set (+1, 2, 4 and 10) and still can't seem to get the camera closer than 1.5' from the focusing screen (canon XL1s - stock lens or with a 50mm lens dirrectly attached to the body of the camera with a 2x conversion on it...so what every that ends up being after the multiplication from the chip size and the 2x adaptor). What is the likely culprit here? How do I make this bad boy macrotastic?

oh...and great site mr. Snodgrass!

Hi guys,

if you cant get that Sanko motor anymore I designed another gg-vibrator some time ago. It uses thin carbon pins and a normal pager motor.
You dont need a pancake motor anymore.

You can also build yourself this device and if you cant get thin carbon pins you may use thin steel pins.

I improved it on my last vacation and now the new VH-57ND design looks a little bit different than this photo.

best regards
Daniel

Cole, thanks for the comment about my site. I wish I could help, but I don't have any experience with the XL1s. All of my adapter work has been on the DVX.

Daniel, I've tried a few types of metal wire and am still not getting great results. I think I will buy your design pictured above (VH-57ND?) to take a look at it.

Cole McDonald May 4th, 2007 10:07 AM

what's the normal minimum focusing distance on the DVX?

Yev Belman May 4th, 2007 02:50 PM

Cole,
see if this article helps any:
http://www.cinevate.com/phpBB2/viewtopic.php?t=13

It talks about minimum focusing distances and has a 37mm by 25mm CAD printout of a typical focusing screen.

On my GL2 it seems i can put it right against the lens and it can focus on it.

Have you tried your snod35 with an HD camera? i'm working on building a similar adapter for my hv20. we'll see how it goes

any recommendations where to get those 72mm spacer rings? they seem to be tough to find nowadays.

Rich Hibner May 10th, 2007 11:21 AM

Anyone know how you get a 51mm Ahcromat in a 72mm Ring?

Cole McDonald May 10th, 2007 11:52 AM

use a 51mm ring and a step up/step down to get there.

Noah Yuan-Vogel May 10th, 2007 02:40 PM

no 72mm spacers, but other sizes on ebay. Think there will be enough space in a 62mm tube if i conserve space a bit more around the 36x24mm vibrating ground glass? what is a normal amount of vibration? does it need a lot of extra space? what is the diameter of the FD mount? what size filter would i need to just be able to glue the filter to the front of a filter?
