Mini35 for HD1/HD10
 
I'm not sure if anyone has stated this previously and if so I am prepared to be attacked but I just spoke with PS Technik and they have the Mini35 for the HD1/HD10 ready to go with a release in late March. Just thought I would let you guys know in case it hadn't been stated.

Do you know what the weight of that will be? I just bought a DS-5 for my HD10u and I've only got about 10 extra pds available on it.

We jerry-rigged a mini35 onto the HD1 once, using the PD150 adapter kit, a 52-58 step-up ring, and a hollowed-out neutral-density-filter ring as a macro-extension ring. Worked really nicely, although with our jerry-rigged setup we didn't have the exact same fov as a true mini35 rig would.

Not sure about the weight. Since the mini35 is a standard piece you can probably find it's weight on the PS Technik website. The peice that is coming out is the adapter to mount the mini35 to the HD10 and I'm sure that only weighs a few ounces.

Price
 
How much a Mini35 would cost, do we know ???

Mark Jervis January 29th, 2004 08:58 PM

According to the PS Technik website, The mini35 adapter kit is $6,240.00, lens mounts range from $145-$270 and based on prices for the other mounting adapters the HD10 adapter will cost around $1,530. So total of $7,195.00 for the cheapest lens mount.

I think you missed a thousand there...

A complete mini35 setup is around $8000-$8500.

Mark Jervis January 30th, 2004 08:13 AM

All of those prices are directly from the website. That doesn't include taxes, shipment, or any other accessories you may need. Just base pricing.

Down with Ground Glass!
 
I'm making a home-brew mini35 adapter for the HDV camera (JVC JY-HD10) and with its 1280x720 resolution, the GG grain issue becomes catastrophic.

After some experimentation with grounding of the UV filter glass, which proved still unacceptable even with the very fine grit (started with 9, finished with 25), I'm waiting on the Bosscreen material... but I don't hold my breath for it either.

So, is there positively no way to eliminate GG altogether? What if we use not 35mm SLR, but 16mm movie primes, thus making the "projected" image smaller and closer to the native size of the prosumer cams' CCD?

Need specs for ground glass
 
Alex, a British company says it can make a ground glass at 1 micron if I provide them with the specs for the glass. I know that it has to be opaque, but strictly speaking I am not certain what specs the gg should have beside being 52mm and made of optical quality glass. If you or anyone else have specifications for the gg please let me know what they are. I will post the results I get from the manufactured process as well as the prices.


Thanks

Dwight, I got great home-brew adapter results with:

- Small glass GG ground with 9micron aluminum oxide

- Vibrated by a micro-motor across the HD cam's field of view so to blur the imperfections to the camera (image stays sharp as it is not moving with the GG)

Will try 5 micron grit today just for the sake of it.

Dwight Flynn April 6th, 2004 09:31 AM

Step by Step
 
Alex, I am going to try both options. Would you take a moment and post a step by step instruction on your vibrating gg procedure. I will compare this to the 1 micron gg method (if the company can produce it.) I am not an engineer so it helps to have some details in this matter. I will let you all know the results.

Thanks

no link?
 
Alex, it seemed as if you were going to post a link with you last reply.

Thanks
