looks good @480p. Hows the noise @ full-resolution?

Good looking images. 720p and 1080p? I wanna try this scene file out when I get a chance but there's not gonna be much light when I get home. =(

I know we're askin' alot. Reason being that the detail settings and such usually add a bit more noise to the image or artifacting. Would be good to see what it does for the image at original size.

The images are both 720p, I just did a screen grab from final cut. The different sizes are not intentional.
I find that you can push the detail up as long as you use the coring and the correct gamma. Detail has much less effect in the cinegammas than the others but these were shot with b-press which is sharper but has less noise. I may be able to put up a short piece of video tomorrow for you to look at.

BPress is Dah best. I'm gonna try these Cam settings now and report back.

Nice looking interview Low Down. I will have to try your recipe.

Those look great Shane.
And you couldn't have better timing.
My Letus Extreme just got here today, and you hit on something that I've been very curious about -
which is, how should my settings shift now that I've added the GG of the Letus to the mix.

I'm going to try these settings out tomorrow
(when I shoot even more enthrawling footage of my back yard)

Nice Job Shane!

Can you post some clips so we can revel in their HD glory?

Jinkeys. These settings really ARE pretty nice and clean. Thanks for sharing them! If I have a chance to post some footage from outside tomorrow I will.

Nice! I noticed that I have some custom settings similar to, but what I didn't do was use the coring and the V. Detail. These settings rock. B.Press AND Cine V look GREAT!

I usually go above 180'. Any particular reason you see to use such an odd number (144')?

144 degrees is the optimum shutter angle for shooting under HMI lighting in 60hz countries. It's not so much of a concern anymore as most ballasts are flicker-free. The setting also helps a little with sharpness when you shoot slo-mo. Overall though, it doesn't make a lot of difference - feel free to use 180.
I need to do some tests to see exactly how far I can close the shutter with the Letus as I was noticing some artifacts when I went to 90degrees at 60fps. Not that I use that setting a lot but I'm just trying to learn the limitations of the Letus with the hvx so I don't get bitten on a job.
Off this particular topic, though, for those of you looking at lenses I've found that the larger the rear element on a lens, the more you can zoom out.
For example, my nikon 85mm 1.4 is vignette free at 20mm (on the HVX ) which means that I can use it on an interview and zoom in about 10 to 15mm before there is a noticeable loss in quality. The zeiss 25mm 2.8 on the other hand needs to start at 24mm on the HVX zoom. So, the faster lenses which have a larger rear element will give you more of a zoom range on the Letus and can be used as a variable prime.

You are absolutely right. I meant higher speed not angle.

I have tried 1/120th with my one touch 80-200 mm f 2.8 AF Nikkor and it looks fine on my 42" Plasma. I had the camera zoom at 55 mm and the lens at 200 mm. (See the duck flapping his wings) http://www.mediafire.com/?8stztjz5yx0

Your other observation is also true. My AF Nikkor 24 mm f 2.8 vignettes even on the Nikon F4 that I bought it for about 18 years ago.

By the way I get full 36X24 mm at 20 mm zoom on the camera. What is you experience?

Your HVX settings are different as far as the Zoom goes. I have to start at about 27.3 for all of the lenses to compensate for vignetting. I'm wondering, though, since I adjusted the LetusEX unit so that the GG is more centered if that's still true.

Hmm. Something to try today when I go to garb footages.

LowDown

How did you adjust the unit for offset? At the camera end with the 3 screws or elsewhere?

Kholi

At the camera's lens with the three screws. Is there a different method? Right now it's as centered as it'll get it seems, I do fear that doing that actually decreases the edge to edge sharpness because you literally have to sort of "tilt" or "lilt" the adapter toward the left or right then lock it into place with the screws.

LowDown

That's what I thought it might do (defocus one of the sides) kind of like a tilt/shift lens.
There's no other way that I know of.
Btw that's probably my next lens purchase- a russian tilt shift:

Maybe it is better to leave it off center like mine is and just zoom to 20 mm. (Full 24X36)

By tilting it you are focusing on a small area of the GG.

I had it like that before, but wasn't happy with the resolution. As it is I don't see the frame pass 18 mm.

Are we even speaking in terms of mm or zoom from 1-100 numbers?

My HVX numbers are set to mm/feet. Haven't been usin' numbers for a while. At 20mm there's a lot of vignette on my camera-Letus combination. Might just be that my HVX is more offset than others.

Were do you get 24X36? if you can at all.

Kholi
01-10-2008, 03:23 PM
I thought it was about 23.7 but I probably have to redo it. Since I've found out about being able to zoom with the HVX lens I've totally ignored "standards" as far as 35mm and Academy and all of that. Just that it's in a 16:9 frame. LoL Amateur buuuut y'know.

Not like my own work is super pro right now. =( I'm always renting and workin' for others.

Douglas Villalba
01-10-2008, 03:29 PM
No, I see what you are saying.

I just use my Nikon F4 to select the lens that I want to use so it help to have the HVX covering the same area.
