My DIY 35mm for Leica lenses...

Hi David,

normally you can mount the VH-72ND directly to your achromat/camcorder but if you get vignetting or you cant focus on gg (depends on camcorder used) you will need some empty 72mm UV-Filter rings to get some distance. From others I know that with a +10 achromat the distance between camcorder and gg should be about 40mm to get rid of the vignetting and focusing problem.

If you cant find a 72mm tube with 40mm in length buy the cheapest 72mm close up filter set from ebay and take out the lenses that should be the right length.

best regards
Daniel

Right now my only problem is with my 28mm lens. that's the only vignetting I'm ever getting. And I've finally gotten my GG to the right distance where the image from my 28mm is in focus (it was blurry before) so it seems to be a good distance for all of my lenses. Any hints?
 
I need more info about your system to help you. Normally with my cam vignetting appears only at about 17mm.

1.Which lens do you use Nikon, Canon...
2.What distance gg to camcorder
3.What Achromat (focal length)
4.Which camcorder do you use
5.Maybe a photos or drawing will help to understand

Daniel:
I use Canon FD lenses with a Panasonic DVX100A, Asian 58mm Macro 10+
Inside the Asian 58mm Spacer ring is my GG, which is 13mm from the bottom of the spacer Ring

The assembly goes from DVX-->72mm-58mm Stepdown -->Asian Macro 10+ -->Asian Spacer (with GG inside) --> lens mount -- Canon lens.

The asian spacer tube is 1.5 inches (40mm) wide;
the Asian macro is 10mm wide;
the 72-58 step down is 3mm wide

so my GG is about 26mm from the DVX
 
Ok,

focal flange for Canon FD mount is 42mm (distance between slr-bayonett and gg). Did you tried to increase the distance from gg to DVX more than 26mm and zoom a little bit more in? That should solve your vignetting problem.

I forgot to ask what focusing screen do you use. Is it a Canon Ee-S/Ee-A or Nikon D with integrated condenser? If not you will need a Biconvex condenser lens also.

Daniel: I use the Nikon D focusing screen. i'll try to increase the distance and report my success/failure. thanks.

Right now at 26mm my zoom is set at 71
 
This is another test for grain and detail I'd like to share. I think my back focus
is just a tad off for infinity focus. I wanted to see at which f-stop that the grain
would show up with the CV40mm. The image is still nice when not @ F16 on the
40mm and I dig the way this lens renders the details. It 'picks and chooses' areas
to render sharp. Pay particular attention to the branches because the DVX renders
thems with a tinge of purple while the Beattie+40mm renders them with nice
neutral colors. One can also fix purple fringing in post if the mood strikes. This is
all very unscientific so don't shoot me. Enough chatter from me...

I'll have a few short clips later this evening. One clip is a grain test and the
other is a focus test. I'll try to shoot some outside footage for viewing later.

A few achromats later... here is the system connected to a DVX100B.

Please conserve my bandwidth and download only! Thanks!

Here's some footage. It really doesn't show much but, atleast it's footage:)

First clip is just a simple grain test. I didn't take any notes on this shot.
The vibration is off and the focus is pretty sharp.
TEST 1

This second clip is just a simple pan to see if grain is present. The vibration
is on. This is with a 1.5v AA straight with no trimpot for motor speed.
TEST 2

Third clip I didn't record the settings and the vibration is off. Noisy DVX blacks.
TEST 3

The Beattie is not very grainy in bright conditions whether the vibration is on
or off. I really need to trim the power to the motor. Included the audio so
you can see and hear the ON vs OFF.
TEST 4


Vignette test. Pretty close to edge to edge brightness on a 24/36mm target.
Could use some improvement but, I'm not worried about it. My fault on the
sharpness quality, I was too close to my cat.

Thanks Daniel! The DVX is really nice right out of the box.

Here's some new outdoor footage that I shot around 11am daylight. I goofed
the focusing on a few shots but, you get the idea. All shots color corrected/leveled
for a neutral look.

Please download only! Thanks!!!

Edit: I forgot to post my scene file settings, I'll do that when I get home.

yes and no actually:( it's a very flimsy material and I couldn't find a way for
it to sit completely flat. I can send you the material if you'd like. I think the
diffusion is right though.

what kind is it? i used double sided tape. i put the tape on the motor side and it seemed to hold in there real well. i'm trying to bid on the V551 phones on ebay, because that was a great screen. I just wished I had never tried to clean it with a cleaner.
 
I thought I'd film something that was vastly more entertaining than trees in a
park so I took the adapter out to the harbor and filmed a street performer named
Tommy Buckets. He has a few misc clips on youtube if anyone is interested.
He's is a mean effin' drummer!

The footage is CC to a nice blueish green and I finally ran out of battery power
for my motor after months of using it without recharging it. I ended up
having to film Tommy with a motionless screen but, it still turned out pretty
nice. I like the image that this adapter is turning out despite what everyone
says about the Beattie bokeh.

This was shot in extremely low light around 6pm. I found the image to be
nice and bright on the DVX lcd and it was still hard to focus. Not to mention
the upside down image. Argh!!!

It'll be uploaded in a few minutes.
 
Alright so my I can't upload this video for some reason so it'll have to wait for
tomorrow. In the meanwhile here are a couple of grabs instead.

you going to do the LCD material soon? i want to compare mine with yours. see if i'm doing something wrong. the amount of grain with the beetie off is the same with mine on, using the LCD material of course.
 
Maybe. I'm not sure at this point. It's yours if you want it... free! I kinda want to
explore the Beattie for now and then work my way into alternate materials. It's
tremedously more expensive as the tradeoff for more light though. Did you win
the V551's yet? I think the material in the cell phone is considerably different
than the film in monitors. I could be wrong... dunno?

and here's my scene file settings...

Coring -7
