My DIY 35mm for Leica lenses...

Well-known member
So after a long road of 3d work I finally settled on Leica lenses and a Beattie
screen for my own custom vibrating 35mm adapter.

It's 58mm in dia with a height/depth of 31mm. Couple that together with a
nice pancake lens for an ultra compact and lightweight package for run and gun.

All the electronics/power are mounted elsewhere to ease weight off the front
threads of the DVX100B. 12mm button is used for the vibration, lipo cells for
power and accompanying components to manage the power.

...and I have zero plans on selling it because of the impracticality of obtaining
costly Leica glass. Besides I'd rather be out there shooting with it instead of
building it!

Here are a few pics of the raw plastic build pieces. It' going to be matte black on
all surfaces for good measure and to make it completely opaque.

Thank you Dan for the inspiration for this. You're knowledge is very much
apprieciated!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The white plastic is the actual adapter piece unpainted. It's a two part system.
I wasn't too keen on the idea of finding a suitable tube and fitting mounts and
filter rings to it. I ended up designing the piece from the ground up. After I paint
them tomorrow night I'll post pics of all the parts. Then I can move on to capturing
footage. The PSP screen initial test is pretty good so I'll post that too.

I believe its a CNC part from a block of white plastic. Can also use Delrin, its a type of black plastic that can be CNC'ed. No need to spray paint after fabrication.
 
I'll post some pics of the build tonight! Oh and Alex yes it can be CNC'ed. The test
pieces were 3d builds-stereolithography. Great process. A bit pricey initially but you
can make molds for multiple parts later just incase something breaks. It is nice
because I can make as many parts as I like to experiment with.

Thanks! Are you going to go the CNC route with your design Alex? I think I
could benefit from a nice metal shell myself.
 
Yes, Its being CNC out as I type this. Should be done by the end of the month. Hopefully to get it sooner though. If you are in the states, its easy to get metal shop around to get the stuff CNC'ed. Where I am from, I had to send the design out to be done.
 
Very impressive,
Pease post screen grabs when you get a chance,
also would like to see some shots or schematics of the power set up.
 
Here's a shot of the motor in place ready for the Beattie screen.

Beattie now positioned and glued in place ready for placement into the body.

Construction of the body and screen is complete with lens in place. Almost there!

I might need an achromat after initial tests and it needs tweaking for the
correct back focus. Other than that it's on to the electronic parts.

Century Optics achro came in today so maybe I'll be able to do a couple of grabs
for this update tonight. The CV lens I have now exhibits more vignetting than your
average Nikon but, it looks so much better stop down for some reason than the Nikon.
 
Where did you get the 12mm button motor? I googled it and the only result that even came close was from the UK. Did you get it locally?

I adapted my design taking a cue from yours, and I'm using a 58mm Spacer Ring with a 10+ Macro at the back. It looks pretty damn good and I finally managed to get clarity with my 28mm lens.... now I just need to get it vibrating and this little button motor looks like the perfect thing.

Clue us in please
 
Here are the very first shots from my DIY. Definitely needed the +7 CO in the setup.

The Nikon proved to be quite the opposite than I had thought. The CV faired better
in every test although not practical for FF gears. I color corrected a shot just to see
what's possible and the results were good. The target size is a full 36x24mm frame
which I would crop in post. The back focus is still off which I'll fix for my next update.

Here are the pics!

puck, I sourced mine from solarbotics. They are all over
the web too, you have to search!!
 
Thanks. I'd actually done a lot more searching after finding that the Sanko motors had been discontinued. I found a few places that actually sold the motor, but then I found a thread that mentioned the motors were used to make cellphones vibrate.

So I proceeded to take apart my old Nokia and found the little motor. I've so far hooked it up to my adapter and I'm in the process of trying to make the bloody thing work.

So much tweaking to do...

Can you share how you're rigging yours up to vibrate? I'm in the process right now of hunting down some teeny tiny springs...
 
Take a look at Daniel's site www.jetsetmodels.info
He has a pretty cool, cost effective, hassel free vibration
device that sits inside a tube of your choice. I followed
the idea in the same manner from the original design
from Toenis. Where is Toenis anyways? I haven't seen him
around lately.

thanks dude. much appreciated. Now I gotta get the right motor... the Nokia vibrator doesn't vibrate it early enough though it does vibrate the hell outt my fingers. So far best clarity is with my static adapter so I'm gonna keep plugging away at it.
 
This was adapted from Edweirdo's design and now combines your focusing screen set up with that. Great idea and thanks for sharing it. It simplified things greatly for me anf finally brought more focus to my 28mm lens.

These are the parts I used to build my adapter:
Asian Macro 10+
Asian 58mm spacer ring

For the GG-Holder I took off the matte top of a 58mm lens cap and cut out a hole to hold the Nikon D Focusing Screen
49mm-52mm step up ring
a washer (from a hardware store)
