New 35mm adapter

i am not sure you can zoom in that much, i think, thats why many people pu the macro diopeter in there, so you can focus closer while zoomed in enough to fill the CCD with the GG image..
 
OK, thanks.

I've tried some basic mpeg2 output and it's ruining the footage :/ So, instead, I'll post some full res DV. Here's clip 1 -- 161mb, 45 seconds long, just dumped straight from the camera, no CC or anything. Right click, save as -- it's in NTSC DV .avi format.

I'll take this clip down later tonight and put another one up, or cut a little something together as a high res QT from more footage, but I just wanted to show these kind of results first as a point of reference.
 
Awesome man...

I don't know if you tested this yet, but I was wondering how far can you stop down before you start to see grain?

just saw the footage

whos the girl? cutie. also i like the quality but whats with the interlacing ? lol

what kind of lens are you using? It seems as though it would be nearly impossible to keep your subject in focus with that thing if they move slightly closer or further away from the caemra. Pain in the butt me thinks? What kind of lens would create a slightly deeper DOF?

That's kinda why I'm wondering about stopping down/grain. I've heard that changing your f-stop will give you deeper dof... I could be wrong though....

You are correct. The larger the f-stop #, the deeper the dof.

f4 - shallow
...
f16 - pretty deep!

However, the larger the f-stop #, the more light you'll need to get a properly exposed shot...
 
Could you boost your gain (provided your cam does a reasonable job with boosting gain), or would that affect the adapter performance?
 
Hmm, I'm not sure about the grain at higher f stops -- I need to do more tests. I will say this -- it was a sunny day yesterday and much of the footage was shot in the 1/800 to 1/1000 shutter range at around f/10, so there was PLENTY of room for stopping down on the lens.

Two more clips: one, two.
 
Jim,

are you not selling the diffuser for the pro? I'm probably, once I get into my new place, going to buy your starndard glass, if this is for sale, I would like both of them.

I'm thinking about that. I'll let you know.

Oh, BTW -- the girl is the future Mrs. Bklyndv :)

Here's a final, longer clip. Right click, save as please -- it's huge (100mb):

Apologies for the erratic shooting -- I had 15 minutes before leaving and shot very under the gun.

laugh, I was just about to post how you shot it and then read the bottom of your last post.

also, is this dvx? or your gl1? i'm not sure, it looks like dvx. i could be wrong, because the gl1 stuff
looked great as well.

i'm an idiot, your footage says exactly what it is...sorry i didn't see that earlier.

Excellent footage, Jim.

Is this using your wax GG? The footage has that feel to it. If it is then im impressed. I know you have been perfecting the wax screen for some time now.
 
I don't think Jim has either confirmed nor denied what his screens are made of. Either way, whatever it is, it's impressive...that's enough.
 
IIRC melt point for typical waxes (e.g. microcrystalline) are around 130-150 F, so melting would only pose a problem under the blistering heat of on-set lights, or if you left an adapter made with such material in the trunk of your car on a very very hot day for an extended period of time.

Needless to say -- I wouldn't advise subjecting any equipment to those kinds of conditions.

all you adapter guys are putting so much time and effort into building this goodies that you don´t seem to find time for shooting hehehe...
BTW, the G35 gallery is gone...
 
True enough! For me this has been a personal quest to satisfy curiosity and prove myself as an effective amateur tinkerer. Now that I know "the secret" of a static solution for SD, I can spend my time perfecting it over the coming weeks and then get back to shooting more regularly once it's released.

Bottom line is that the mainspring of interest in this project has always been for me creating a viable solution that I will be excited to shoot with; that looks nice and performs consistently.
 
Incidentally, the one fleck of dirt/dust that creeps into every one of these clips is actually from inside the GL1's lens setup. I can see it clear as day sitting there as I look into the lens, and it bugs the hell out of me :( I just don't have the time in my schedule to send the cam off for refurb while developing the adapter.

I'm looking around to find high quality achromat suppliers so I can make this adapter work properly with the DVX. As of now it works just fine with my GL1, and presumably then it works with the GL2 just the same. Probably works with any 58mm lensed camera -- the whole line of Sony VX's. But initial testing with the DVX leave me miffed that I'm getting a little edge smear with the optics that work just fine on my GL1.

Someone asked about release dates: Go35SD and Pro will go for sale in three weeks -- around April 17th-20th. I will be double checking with my supplier and confirm this week if we're on track. There should bea working prototype of the Go35HD in two weeks. Once it's proven, I will set mass production in motion and it will be my guess another month to get them rolling in.

I'm hoping to get some achromats cheaper than current suppliers I know and if so, the Pro's price will fall a bit. I really would love to get it below $600 if possible.

So Jim, are you still going for a $209 static adapter?
Click to expand...

Yes! Definitely. That's the Go35SD -- $209 for a great little product. It will be ready to go out the door as soon as the parts get here (supposedly shipping April 10th, arriving 4-6 days later...)

I'm hoping the pricing structure will look about like this in the end:

Go35SD -- $209
Go35Pro -- $530-580
Go35HD -- $700-720
