Another DIY 35mm spinning adapter.

cinebuddy, i'll make sure you're one of the first "peeps" that gets a tutorial. and with the extra money you saved by making one, you can buy pair of new fresh kicks to sport around in.
 
Cool I like those fresh airforce ones with the cotton candy colors. Dude I can't make one, it'll be all f'ed up. Flange distance off, glue everywhere. Like I said I admire you builders. Those who can do...the rest of us use paypal.
 
Cinebuddy, that's the cool part about this. I'm doing it for guys who say they can't. The tutorial will have a step by step process to where all those issues you mentioned are eliminated. I hate glue. I won't use glue. Flange distance will be a thing of the past with the ability to move your lens mount back and forth.

Now, I do understand where people can't use a drill, or don't have one, so that's why I condone just buying one, and if you have the money, even better. But, a good portion of people just don't have money to spend on adapters. Or they do, but they'd rather cut the cost of 35mm adapter and spend it on lights. That's what I'm about. I have stated in the past, I think they are overpriced. From my point of view, they are. Maybe because when it's all done and built, I'm thinking "wow, that wasn't expensive at all to build.".

So yeah, buy and adapter if it best suites you. Build one if you think you can.
 
Hey im all for the talk, lets see it in action. I am about 2 weeks away from the BEER CAN Mark 3 spinning adapter with super secret ground glass...plastic.
ill post up when I can

Don't take my beefin with Car3o over price as doubting his skills. The hardest thing for me would be going back to a non-flip solution, buy i'd be lying if I said i'm not mad interested to see and test this out. I've been diying alot of things like flags and scrims. The only thing we disagree on is R&D but his project may change my mind on that as well.
 
Just finished my 35mm adapter. check out the footage here http://www.vimeo.com/1169907 This was shot on my Sony FX1 with my DIY vibrating adapter. Ground glass holder is the wobbley legs design I made since Daniel didn't answer my emails for order. I am using a SGpro achromat and pcx lens in front of the achromat. I will be testing the pcx lens in front of the ground glass as I noticed that I had chromatic abberation and barrel distortion with this config. I might be this kit available to those who want to make a DIY vibrating adapter.

why dont you try removing the condenser altogether?

I can still see a bit of GG pattern when you pan, is it perhaps the posts of the gg are too taut? or the motor too slow, but your doin great progress there!

its probably a minor tweak but as someone told me, the later into the learning curve the tweaks and changes get more minute.

Good luck
 
I'll try to remove the pcx lens and see if the vignetting is heavy. Actually I have a variable resistor hooked up to the motor. I noticed if I pumped too much current, the motor would vibrate really fast thus making the movement of the ground glass very little. The problem is how do I see the motor vibrating when everything is enclosed. Zerg, the sgpro achromat is 70 UKP and the pcx lens is USD$45. The ground glass holder and motor cost about US$10. Tye ground glass is ground by myself and the compound cost US$20 per kg. The rest of the items you guys should be able to figure out. Here's the footage of the vibrating motor in action shot at 120 shutter with my Canon HV20. http://www.vimeo.com/1175870 Anyone seen how the brand adapters vibrate? I get better results when I use slower rotation.

its vibrating right when you "cant see it" vibrating. can you post footage when youve increased the current? I think your almost there.

Try to do a test without the pcx. The sgpro achromat is a good achromat.

So to everyone using the vibrating ground glass; are you not concerned that the constant cibrations will slowly damage your camera?
 
Why would it damage your camera? Everything should be locked down pretty good?

Side note: I finished my spinning adapter with my secret ground glass. all the footage is incredibly soft because the colimnation is completely off. I was going for adjustable however its far too much work. I understand why the big boys charge so much.

Here is my setup.
TOTAL COSt. 16 dollars.

duct tape- 5.00
screw. nuts and bolts-9.00 dollars
Acrhomat ( 2 magnifying glasses from Dollarama ) - 2.00
wood- scrap
pvc pipe-scrap
Ground Glass- SECRET...

Here is a grab from the adapter above. There is alot of grain, vingetting and CA. However, the fact that I spent 16 bucks and a couple of hours far outweighs these small problems. I mean I wouldnt use it for everyday shooting, but it has its place.
Footage to follow.

Hmmm most people who shoot with adapters never shoot without them. Well I don't anyway. Even at 16 dollars I don't see where the above image has its place. What's the point of focus in the shot? Everything seems soft which may just be back focus etc. Sorry that's a tad to ghetto for a man from the ghetto. As to the vibration damaging the camera...no worry here. What exactly is it going to damage? If a pager motor jars something loose in my $6000 camera then there's a f'ng problem with the construction quality of my camera.
 
again CA is a huge problem, so is it being soft which, since I have readjusted the focus, is probably due to the GG moving back and forth. I am going to crank up the juice today to get rid of that flickr esq thing that I have going on.

Thoughts?
