Spot.

It looks very good indeed. And yet, color abberation. It's the only bad thing I can say.

Am I expecting too much? Or is this an issue that can be fixed?

[QUOTE=Obin Olson]it's off

It really looks like the gg is not moving fast enough and the camera is "seeing" the grains that are now much larger in size and softer then if the gg motor is off...I don't know how to fix this, would weight on the gg make it better? I have used 4 AA cells on the unit and it's better, but still doing the same thing, and this is somthing you can see at 1/48 shutter...it really shows up on a wall or sky shot, less detail in the image shows the "screendoor" effect...

Obin, this describes my experience down to the last detail. Are you using an XL2, Sony, DVX? Quyen, I will try your suggestions and see if this works.
Thanks!

It's a little too soft and too shallow for my tastes. But delicious footage nonetheless.

Kurt August,

Color abberation can be improved and we are working on this issue.

Eric,

Are you using XL2? what setting are you using? Did you see grain on white walls, the sky, or everything? I will test it myself later this week to see if I get the same thing.

Thanks

Quyen

Hey, Quyen.

Yes, it is the XL2. Settings are:

-3 gain
1/48th shutter
24p
16:9
f1.8

These were intial settings. I've stepped through different f-stops and shutter speeds and the effect remains. I've also tried the OIS on and off and this doesn't change it either.

I'll attempt the loosening of the gg as you suggested and the cleaning and get back with a post sometime today or tomorrow.
Thanks, Quyen.

I am getting MUCH better results with the 4 AA system now..I will post some HD test shots with the reel stream setup

still I think we need to re-think the plastic that holds the GG mount as I think more rubber would allow for the GG to "move" a bit more and really get rid of the "screendoor" effect on this unit, improveing it 1000%!!

Quyen???


maybe use some of the rubber from a CD-ROM mount? it's VERY soft and would allow for more play in the GG ...

BTW I made a rail mount for the unit and it's SO MUCH BETTER , you can touch the lens, focus etc and the thing does not move at all, no image shake in the shots from pulling focus now!

anyone who has the unit NEEDS to do this mod, take it to a professional level.

Obin,

Thank you for your suggestions. I will do all the possibility to get the GG plane to spin faster. Do you have a picture of your rail mount? Thanks.

Quyen

HD test in a min...compressing it now

Quyen, keep in mind that you will be dealing with LOTS of HD cameras soon, every glass element you have in your unit will have some results on teh final image, I know your unit is not that much money, but put the best glass in it you can afford, we will all see the results in HD ;)

Quyen Le, could you post a clip shot with the lens stopped down, so the DOF wouldn't be so shallow? Then we can have a better idea of the sharpness of the adapter. As shown in this video, it basicaly not usable for my applications. If you project that, it will look like it's all out of focus. Just not sharp enough.

Obin,

I cant download your footage, you URL looks odd?

Thanks,
Wayne

Obin, so far this is the best Lestus35 footage I have seen. It may be because it's HD rez, or because you are using the Micro35 achromat lens, which would indicate the Letus35 macro is of lower quality. But even though, it's nothing extraordinary. I think your footage with the realstream and the micro35 DIY looked sharper. Could you post some footage shot outside, maybe some trees, with wide shots and close ups?

Ok,
The URL had //// instead of // downloaded now. Footage looks great, nice and sharp. What strength macro are you using with the dvx100a?

Thanks,
Wayne.
