Fiber screens, the future of the 35mm adapters?

OK guys you ask it... you get it...

Ok I have eight, sold one, I keep three another four to go...

the flattening is evident... but it leaves a clear aperture of 34mm x 23mm... this side goes to the camera... polished...

And this side goes to the lens... AR coating, polished...

Notice how it replicates the logo on the center (that the cup is touching the screen) and how the bokeh looks on the edge of the logo...

Good for you Eveangelos...I hope you sell a lot of these. If I was still in the market for a focusing screen, I'd definitely pick one of these up.
 
texture

Thanks Evangelos,

Nice to see the screen. It has a texture in the surface, very interesting this texture are not shown in the image. I was wondering how it works...
 
The texture are the fibers... when we see through the fiber screen, totally perpendicular, the chicken wire structure is invisible. Its visible only when you see it in an angle...
 
Evangelos,

So the price for one screen would be about 330 euros + shipping...? Is that correct?

So if one were to make their own adapter all one would need is:

1. a tube
2. 72mm step ring for a dvx100a camera
3. an achromat
4. a nikon or canon mount
5. various spacer rings

I'm trying to see what the overall costs would be for a diy'er.

For a static yes, I would suggest either and RNG35 or a Brevis 35 or Daniels vibrating holders just to have the vibration option at will, in cases that the lens needs it, or the aperture is F8 and above, or a small blemish/dust is in the size of a pixel is visible...

Rememberthese screens are passed quality approval with blemishes in less than 25microns size, that's a pixel size...
 
condenser

condenser

I did the download of the two footages, the demo and the stop down test. I would like to know if you used a condenser or just the fiber screen and the achromat?
 
lenses to test

lenses to test

I will sugest some lenses to test in this same configuration, without a condenser with a stop down in footage:

tokina 17mm f3.5 (old manual focus) in canon fd mount or nikon mount
canon fd 17mm f4
canon fd 20mm f2.8
canon fd 24mm f2.8
canon fd 28mm f2.8
nikon 18mm f2.8 or f4
nikon 20mm f2.8

these lenses vignette a lot and would be great to see the performance with the fiber screen without a condenser shotting a blue sky or white wall...

thanks

We had build, about six months ago, a relay lens for 2/3 cameras like Varicam that was specific for Brevis 35 and Super 35 format.

Due to huge demand from users that had an HPX500 or a Digital Beta camcorder I decided to do the extra effort and build a Rev2 of my relay in order to be available for ALL adapters flipped and non flipped, including covering both photographic frame 36mm x 24mm and Super 35 24mm x 13,5mm, as well as to have adjustable iris from F2.8 up to F8 instead of fixed in F4.

The new relay is with filter thread of 72mm, so it fits to all adapters. The length of the relay for a LEX is about 70mm from B4 2/3 flange to the prism of the LEX.

All the test that I conduct is being shot with my Varicam and the new relay.

The relay is available today...

I will do a test with canon fd 24mm f2.8... that I have...
 
canon fd 24mm f2.8 will be great

canon fd 24mm f2.8 will be great

canon fd 24mm f2.8 will be great with a stop down... let the camcorder in auto iris so the camcorder can compensate the light when you stop down...

waiting to see...

thanks

So just to be clear about things, how much do these screens cost?
Click to expand...


When I asked the regular price is around 350 euros or 448 usd(fluctuates with exchange rate) plus 50 dollars the shipping with UPS saver.


He's selling the test screens for around 200usd because they're not the final design.

To the dude that bought one, can you do some tests once you get it?
That would totally rock.

Another concern with the Brevis is weight.

The GG plate sits on two dainty rods. This fiber GG looks heavier. Is there a risk of breaking the rods. Did you consider that?
