DIY micro35 kit (New Footage!)

Re: DIY micro35 kit (New Footage!)

it looks far btter than the standard dvx lens, aside from the shallow depth of focus what other qualities does it offer the dvx look? the colours definitely seem brighter
 
Re: DIY micro35 kit (New Footage!)

The flicker was resolved long before I shot the footage. I just messed up and left the old one (GG) on. But after the hundreds of responses I've gotten so far (people wanting me to provide them assembled), I decided to look into something more "production" for a GG. Solution found (ended up being a higher resolution gg at a fraction of the original cost!). They're being made as I type this.

Any jerkyness during the pan was probably my gigantic bogen 3066. The adapter is free of vibration.

By the way, the post of the horse footage was NOT color corrected AT ALL. That is straight out of the DVX default F6.
 
Re: DIY micro35 kit (New Footage!)

How is the spinning CD powered? Does it draw much? Or did you go to a 'static' GG solution?

I signed up. Nice work.
 
Re: DIY micro35 kit (New Footage!)

Hey Redrock, any tricks up your sleeve on eliminating the lens pulsing during a rack focus?
 
Re: DIY micro35 kit (New Footage!)

Yeah! Get a better 35mm lens! That video (at least the big rack scene ;) ) was with a loose old canon lens, and not with the sigma...

I'm sure a follow focus would help too.
 
Re: DIY micro35 kit (New Footage!)

This looks perfect for what I'm looking for, hopefully you'll have the system perfected around spring time.
 
Re: DIY micro35 kit (New Footage!)

The pulsing you are refering to may be what is known as "breathing." This isn't an inherent problem with the adapter it's a problem with your lens. What happens is the focal length of your lens changes ever so slightly when you change the focus. This isn't noticed in still pictures but shows up dramatically in video. Since still lenses are not designed for video you may have to experiment to find lenses which do not have this problem. Generally speaking though a cheap lens will always have this whereas a high quality less has lens chance of a problem.
 
Re: DIY micro35 kit (New Footage!)

I imagine the pulsing/breathing could be resolved with renting a set of Arri primes ;D

...but what would be a 35mm still lense that minimizes this problem? I guess testing will be the only answer?
 
Re: DIY micro35 kit (New Footage!)

Yeah, testing is the only thing I can think of. Each lens is different in that respect.

Wish I had a set of Arri primes!

EDIT: This is assuming that the problem you are seeing really is breathing. Is this the shot of the rack focus with the horse and the fence?
 
Re: DIY micro35 kit (New Footage!)

The more I think about this the less like breathing your problem sounds to me. I think you're probably still seeing the effects of the old ground glass.

That said I just watched the footage again and there is slight breathing on the first rack focus (horse -> fence). Can't see any on the second.
 
Re: DIY micro35 kit (New Footage!)

Wild speculation, but how likely is it that you'll find a still-camera lens that doesn't "breathe"? It seems like when designing a still-camera lens, the designers probably wouldn't care one fig about whether the lens breathes or not, because still-camera lenses are inherently designed to be used in single-shot circumstances, so breathing would never be apparent...

Not saying that there aren't still-camera lenses that don't breathe, but I can't imagine that being a design priority...
 
Re: DIY micro35 kit (New Footage!)

I was finally able to do a quick test of my adapter last night at it definitely breathes. I'm using a 50mm Canon FD f/1.8. I just bought it for testing as it was only 20 bucks. Of course, I still need better diopters which would let me zoom in a bit more. Which probably just exaggerates the breathing. Hmmmm. Oh well, the footage was exciting to me, if not very stylish. I have feeling that after al of this work I'll end up buying redrock's. :o

Re: DIY micro35 kit (New Footage!)

Another question would be what lens to choose that could be adapted for a follow focus rig - redrock, maybe you could figure out a package with a Micro35, follow focus, mattebox (bet you could whip up a shade to go with a support system). you could build this around two lenses (super wide, tele) (maybe Sigma, they are easy to adapt, economical) that you could test and reccomend. A sort of "production package" for the serious user on a reasonable budget.

Then the only thing left would be a geared head that fits on a 75mm bowl tripod (a microWorral instead of miniWorral).

If we had similar production tools to some of the big boys, we could all really kick some ass. We are already so close with the DVX and NLE.
 
Re: DIY micro35 kit (New Footage!)

Sounds interesting... May need to get someone like Barry to help me out with a good lens selection. I could handle the fab work... I've already got a couple of Follow Focus mfgs calling...Although I'm kinda getting the bug to design one. Mattebox should be pretty simple..
 
Re: DIY micro35 kit (New Footage!)

Redrock -- you're mounting the 35mm lens by modifying a rear lens cap, correct? Have you tried/considered using the front half of a C-mount adapter instead? The adapter unscrews leaving the camera mounting ring and a metal lip on the back for mounting to the other half (if that makes any sense). I'm using it right now on my own adapter. Just thought it might be a little bit more secure than a lens cap. The one I'm using is here: http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=116732&is=REG

Just a thought.

Re: DIY micro35 kit (New Footage!)

I like it. But that mount costs more than all the materials for the whole micro35 adapter.

I'll have some details on that in the guide...
 
Re: DIY micro35 kit (New Footage!)

Oh really? Well, I hope you get your guide posted soon before I waste any more money on my efforts. :D
 
Re: DIY micro35 kit (New Footage!)

I think a package would definitely be cool. I wouldn't want a lens included with it though.

Barry, good point. I've noticed that the breathing isn't as bad (or even noticable at some focal lengths) with high end still lenses. I don't know why this is. Surely it isn't an intentional thing as you point out!

Redrock, are you going to be adapting the adapter (heh) for each individual brand?
 
Re: DIY micro35 kit (New Footage!)

Redrock -- got your email. Very exciting. Any idea when the kit will be available? If it's going to be a while I'll just get the guide, endure a long period of frustration, and then buy the kit. ;D

Also, if anyone wants to buy a ThorLab 52mm tube, a 50mm OptoSigma GG and PCLX lens, plus other miscellaneous parts for a static adapter, let me know.
