I forgot, it had 6db of gain, that mames HD really grainy..I think outside footage will be really nice as you have so much light to work with


I can also tell you that the micro35 Achromat is MUCH MUCH better quality then the standard one that ships with this unit, I could not shoot HD with the standard Achromat.

Michael Maier September 19th, 2005 05:22 PM

Somehow all the footage I have seen from the Letus35 has been the most soft of all adapters. I have a real issue with sharpness. In my opinion, the sharpest of all these home built adapters, was the one made by the guy who converted the FX-1 to exchangeable lens. I think he was an Italian guy. The clips he posted were INCREDIBLY sharp. Neither the Micro35 or the G35 and certainly not the Letus35 produce nicer or sharper images. But I don't think he's selling them. I wonder what he got right.

I can tell you why it was sharp, he removed the stock lens!! that is the ticket, and what I will do soon on our dvx.

It's a SOFT lens, trust me.

Yeah, he had some other lens in there. What was it?
Do you think that lens was better quality and made the difference? The thing is he shot with a FX-1, which is HD, and his adapter held up great. You said the Letus35 doesn't. So the FX-1 guy did something different. Was really just the removal of the stock lens making the whole difference? If so, one could get similar results with a XL2 or HD100, which are exchangeable lenses.
I wonder how he got that lens to work with the whole system. It wasn't a zoom. I wonder what focal length etc.

You lost me here.

Michael,

Obin means the original lens on the DVX is soft. Hope this helps.

can you shoot me a link to the guy that has the lens off the Fx cam? I want to talk with him about his relay setup for that system

The production G35's will be shipping with a bayonet mount for those cameras without a fixed lens, (XL2, HD100..) and threaded (obviously) for those cameras with a fixed lens.
As an XL2 owner I'm hoping this will help increase sharpness as I don't have to worry about "stacking' glass.
the Letus35 does produce great depth of field but does run short in the area of sharpness. No matter how much I try I am unable to produce a sharp picture with my camera and lenses.
But, this is a first run production. Perhaps Quyen will go to a different achromat eventually?
In the meantime I am patiently awaiting the G35.
But, yes, that FX-1 footage was indeed sharp! HD seems to love these adapters.

Obin, did you see Sean Porter's problem that cropped up when he replaced the stock DVX lens on his camera? What do you think the problem was with Sean's design?

He never posted a response so I'm wondering whether he resolved the issue.

Are you sure? Maybe Jonathan will verify and clarify...

So what's exactly involved in this conversion? Do you know?

Bill Porter September 20th, 2005 01:29 PM

The links still have some pics up in the gallery but not all. The conversion consisted of removing the stock lens, grinding off a couple of little plastic bits that were in the way, machining and installing a metal adapter plate, and mounting the new lens.

Obin Olson September 20th, 2005 03:48 PM

it's amazing the image quality of the new lens, and that's an SD lens?

shot a professional 30sec tv spot today with teh Letus35, really really nice footage from it, I will post some when I start to edit.

I read it at the source. It's one of the newer posts. Hopefully I'm not mistaken but I 'm positive bayonet mounts are indeed available.

One of the reasons I have not bought the redrockmicro.

Here's the thread:

Eric, I read the entire thread again and I think you are misunderstanding Jonathan, or I am misunderstanding you, LOL

I got the impression you meant that the G35 would allow you to omit the original XL-2 lens and mount the G35 directly to the camcorder without a lens on the camcorder. If this is what you meant then I think you are mistaken.

Obin,

Are you refering to Matteo's lens or the lens you used with the LETUS 35 for your TV spot?
