Re: DIY micro35 kit
Thats pretty cool stuff, but its just the blank cd design all over again.
Probably the main reason there's so much talk is the fact that i pretty much have no cash to start building this all.
Hans: You might be thinking of a retroreflector (180 deg. deviation). A roof prism does a 90 deg. deviation.
The roof prism would take place of the mirror set at 45 degrees. It would reverse (correct left to right) the image and deviate it 90 degrees toward the pentaprism which would deviate it another 90 degrees to the camera. slr designs have an all in one penta roof prism(see earlier post).
those guys at DVi have decided not to use pentaprisms and the like to correct the image and are sticking with the cd design for the most part (though some have opted for a vibrating design)
for the sake of not sifting through 80 pages of posts, why are they using fresnel lenses???

Dig further and check out the links. For example, the "Blind Cat Films" site.
To reduce the image to fit the roof pentaprism? It looks like it's hard or expensive to find a roof pentaprism large enough for the images.

Re: DIY micro35 kit
Barry, as you know the only way the Mini35 works is by forming an image on the gg that is re-imaged by the video camera. If you used an aerial image system (no ground glass) you could improve the sharpness but loose the depth of field of the 35mm image and wind up right back where you started with the same depth of field as the MiniDv Camera alone at the same FOV.
As the ground glass or what ever medium is used to form the image becomes increasingly fine, it starts to become transparent and prone to hot spotting and even vignetting as the system more and more approaches an aerial image situation.
In my experience, there is never anyway to get a sharper image using complex relays etc than the original camera recording with a quality lens directly. The additional optics invarilably degrade the image quality.
Quality, well engineered devices like the Mini35 give you the "look" but the image is not as good in terms of resolution and contrast as the camera alone-- which does not mean that it is not good enough, or that the benefits of the shallow depth of field etc may not outweigh some loss of resolution and contrast, it is a trade-off and a choice.
My experience with professionals tells me that one must never confuse making a video that looks film-like with making a video to be transferred to film--they are different things and many times require different techniques and choices.

Re: DIY micro35 kit
I have been thinking that the DIY Mini35 could come in useful for a few specific functional needs.
For example, I have a scene planned where someone is running down a long hall during a dream sequence. The effect I am after is a for a focus to follow the individual as he goes down the long hall, forground and background focus changes as he moves away from the camera.
For this scene, i desire some tunneling and vignetting, and slight loss of contract and light, so the Mini35 I believe might give me a unique surreal look.
I don't think the home made mini35's as they exist today would be good enough for a full length feature, but it could be a tool that may provide some "special effects" type scenes..

Re: DIY micro35 kit
Sorry guys! I've gotten carried away getting my machine shop put together! I should be able to knock these out pretty quick. (With the rails and base if your interested).
I plan on taking some time this week to post some more footage.

Re: DIY micro35 kit
I'm going to offer the spinners first. I got a lathe and have been perfecting the offset shafts. I've actually been practicing my metal shop by building a 24' jib/crane with pan/tilt... Modeling it all first then building to the specs...
should turn out well!

I would also like to know how much and also if it would work with another camera besides the dvx

Re: DIY micro35 kit
Given that I am in the Optics business and have been for 400 years and always will be.
how about I use two tetraprizms and one giga-hexaprizm
and a shoe box and some PVC rods
Red Rocker please keep us posted on YOUR work
that footage is dope,
I saw that lil' wal-mart drum set
and also when u turn the ground glass on again I can se some motion like on the wall.....
maybe it's just me
Micro35 is a good name so u don't have any problems with PS Technik
so please keep us posted

Re: DIY micro35 kit
Redrock,
The footage looks amazing.
The close-up of the little girl looked real good. You should Post a vid once you get the new diopters set up. I'm not an optics master, but I though the rotating glass looked just fine.
...Hey Bill, what do you think?

Re: DIY micro35 kit
Redrock is your setup working on a 100 or 100a...
I have a 100 and would really like to get this system
Great work.
