Any shot anything with an FX1 - using a DOF adapter?
 
I am looking for some examples of films, docs or shorts shot with the HD Sony FX1 with a DOF adapter on it.

Thanks

Try a search for 35 and fx1 from the menus above.

Here's a link to a search I've done for DVinfo.

Link: http://www.dvinfo.net/conf/search.php?searchid=570495

The link is for fx1 with a Letus 35 adapter.

I own a Letus and happy with the purchase. Quyen is great at helping you out with any questions you may have.

Note that the link is only a search on fx1 and letus 35. You will need to modify your search for the other adapter tests.

Thanks, but there wasn't one clip with FX1 and the letus. There was a film-transfer, but nothing else. Checked through all of them...

Wayne Kinney July 21st, 2006 08:35 AM

One of my FX-1 customer's are currently shooting Peter Gabriel's new music video with the SGpro. He will be posting results in time...

David Delaney July 21st, 2006 08:48 AM

Thanks Wayne, I have alot of respect for your product. The stuff looks great.

If you go here :-

http://savefile.com/projects.php?pid=618011

and scroll right down to the very bottom of the web page, the link to a clip is still there. It is a half-aize H264 clip so you will need quicktime or the free downloadable VideoLAN player to be able to view it.

The clip was shot with HDV on the FX1 for DVD "special features" but transcoded from the camera as MiniDV into the NLE for cutting, then recoded to H264 for placement on savefile.

Shot with modifed AGUS35.
( Prism erecting version )
(AO5 spinning groundglass disk)
SLR lens 85mm f1.8 wide open.

Sony FX1. (9db video gain, PAL, shutter 1/50th on-camera mike so bad audio.
Lighting - (production lighting for the production camera, a JVC HD100.)

Lighting consisted of a large theatre spot aimed at the ceiling, two 1000w lowels with filter gels and masks.

This clip has been sent along with other footage on a tape to Maheel Pereira in Sri Lanka who has developed a film-out process and is testing footage from various devices for filmout performance.

David,

Here is a pilot I shot with the FX1 and Letus35flip. We shot this at night with three 1k Lowel lights.

Here is some footage from a short I shot with the FX1 and Letus35flip.

That is all I have on the web. Hope it helps. let me know if you have any questions.

If you do a little searching there is a lot of stuff out there with the FX1 and DoF adapters. Look at the stuff shot by Macgregor at http://www.cinemek.com. That guy has some amazing footage with his FX1e and G35. I think there is some footage on the Red Rock Micro site also.

David Delaney July 21st, 2006 12:44 PM

I wonder how much the interlaced footage hinders the DOF...

Robert Kirkpatrick July 21st, 2006 12:58 PM

I'm hoping to have some FX1/Z1U footage with a SGPro posted soon (like real soon). Right now, I have a short test reel of about 1 minute -- but I was hoping to do more. My next short will be shot with it.

Why would it do that?

David Delaney July 21st, 2006 03:30 PM

Well, I tried deinterlacing and find it makes the footage soft.

BTW Ben, didn't you used to have the Letus? Did you change your mind?

Ben Winter July 21st, 2006 04:23 PM

I did sell my Letus but apparently the focusing screen size/achromat power combination wouldn't allow a DVX to zoom in enough. The same issue arises with an FX1; I'm going to rebuild it and see if I can tweak it to better standards. Then I'll probably work an internal rechargable system into it and try to sell it again.

What did you use to deinterlace? I highly recommend DVFilm Maker as it is a very agile deinterlacer; it keeps very close to all of the resolution.

David Delaney July 21st, 2006 06:01 PM

Ben I would recommend putting a condenser right in front of the camera lens. It has helped me immensely. I am finding that will the RedRock as well, vignetting - not sure why ,but I think the SGpro and the Brevis don't have the vingetting problem...true?

As for deinterlacing, I am using Video Vegas, separate fields etc.

Dustin, the first movie was amazing looking. Very sharp and even when it was dark - it still looked good. Did you get any vignetting with it?

Ben Winter July 21st, 2006 06:18 PM

Actually david the issue was that the focusing screen wasn't big enough--I was using the Beattie for the Contax which I guess crops a little too much. I'm experimenting with thin-film materials which should allow me a bigger projection area.

Albert Rudnicki July 21st, 2006 06:20 PM

HI David
I made this post before in other section of this forum, but i think it's a good example for you of a 35mm adapter combined with FX1.
The adapter is M2 from redrock

Did the original Letus GG not do it for you?
I wonder why some footage is soft? Do you think it is the GG or the achromat?
I was thinking about the homedepot bags again. I think the best method would be to stretch one of those bags across the Letus 'hole' and use it as a GG. It would be thin and have less light loss.

Mikko Parttimaa July 21st, 2006 07:35 PM

Really soft image is usually a combination of bad GG, achromat and lens. Sometimes distance beetween lens and GG can be off. I have even heard that HDV codec doesn't like highly visible grain too much. This could also soften the image.

Letus seems to be the softest adapter out there.

Ben Winter July 21st, 2006 08:49 PM

David, those home depot bags are singular-direction diffusors, in that they only diffuse in one direction. Don't know what I mean? Basically, really, really ugly bokeh.

There are bags that universally diffuse though, the trick is finding them.

Ben Winter - FX1 - dvfilm maker - tips?
 
Hey Ben,

Before I go and buy DVFilm maker, any tips on it? I have the FX1 on rent right now, so I am trying to figure out as much as possible in a short amount of time...

Ben Winter July 22nd, 2006 05:16 PM

I haven't honestly played around with it much, but I did do a comparison a while back between FX1 interlaced and de-interlaced footage.

On my 42" plasma, 60i -> 30p looked about the same (except being progressive of course). 60i -> 24p looked fantastic as well but I think I could see a little resolution loss.

The settings menu is pretty straightforward, I didn't play around with the 24p editing options since I wasn't editing the 24p segment, but it looks pretty powerful. The only silly stuff is the red boost? and the "add grain" thing which I haven't really tried but from the sound of it appears silly. I'd think anyone halfway professional would do those things in After Effects or something similar. Oh well.

Overall, I wouldn't trust my deinterlacing to any other program, and its half the reason I own a Sony cam in the first place.

Dustin Cross July 22nd, 2006 08:56 PM

David,

No vignetting with the Letus35flip and the FX1. Just make sure you use a monitor with underscan to verify how much to zoom in. With the LCD you are getting overscan and it will look like you aren't vignetting, but you are.

I have a friend here with an Red Rock M2 and we are going to do some tests between it and the Letus35. See how they compare with lightloss, resolution, CA, etc.

With the little bit we played with them it seems they are about the same in light loss and resolution. The Letus flips the image and has less CA than the M2, but the M2 has no noise when the lenses are stopped down, where the Letus is only usable from wide open to about f4.

Andrew Dean July 22nd, 2006 10:18 PM

I shot part of a short film using an fx1 and a letus35 flip enhanced. I put some frame grabs and a clips at http://www.5501.com/adapter

cheers,

I forgot to mention that you can do a check for Nicholas Bartleet on Dvinfo.net or go to his website at www.pixelloft.com to see what's he done.

He uses a homade adapter with his fx1. His work with it for a musical group called 3L was used by Sony on their HDV tour. The groups video also aired on MTV.

Check out Akala music video as well.

Wayne Kinney July 23rd, 2006 11:25 AM

Nick's just posted his newest music vid here: http://www.dvinfo.net/conf/showthread.php?t=72041

David Delaney July 23rd, 2006 12:34 PM

The images look great, even better than I had hoped for with the FX1. I was worried about sharpness because I think the LetusFlip has a much better GG/achromat/macro than the Letus35A.
