Static Adapter

Has anyone started making static 35mm adapters for sale? Is anyone willing to?

this may seem like a pointless post but, why buy one? a static one would be pretty simple to build...

I think there are two or three... Indie35 is one. Also Jim Lafferty says he will release a couple varieties as well. Tim Johnson does make a point, too.

mainly a time restraint and not knowing exact measurments or having to look through all the forum posts

well the measurement between the gg and the 35mm lens is easy, you can find the info on google. I know for the Nikon F mount its 46.5mm :). the distance between the gg and dv lens is pretty much down to trial and error.

used ae to create animated depth maps using masks, opacity, and alpha channels, then used DOF Generator to batch. will do a longer clip when i have more time. stock vx2000, 24p using my own recipe

i like simulating it because then i have more control over the image and no loss of light or grain, sure it takes longer, but i guess i like the control.

That's right, I will be selling two models of static adapters soon -- the Go35 "SD" and "Pro." I'm in the home stretch of developing them -- it has been a far longer time in coming than I hoped and expected but I am just waiting now for the custom achromats to be machined and shipped. ETA is about 7 weeks.

You can see test footage from earlier beta units of the Pro here:

Nearly every clip above has some sort of issue, whether it is that the clips were shot interlaced; or shot with my GL1 which has dust in the lens chamber; or shot using an inferior PCX lens versus a good achromat and suffer from edge issues or chromatic aberration. They're just tests -- so, while they're not a completely accurate indication of the final adapter's performance, they should give you a good idea of the grain and diffusion.

Speaking personally, if you're looking to be a filmmaker, and not a hybrid machinist and optical engineer of modest experience and training, then I suggest purchasing a prefab unit. Not just one of mine, I'm speaking as a matter of general principle -- while a single DIY unit could save you money, the mistakes made assembling one (time and financial) generally shrink the assumed savings considerably.

Then again, it is an interesting experience and you may (like me) enjoy learning by breaking and building things :)

I must say that I agree with Jim. We are near the completion of the DiGi35 static adapter and let me tell it has not been an easy ride. To produce the perfect static adapter takes a helluva long time to perfect and requires a substantial amount of finance to do it right.

Precision engineering, flawless optics and the perfect GG is needed to make the perfect static adapter. In the long run you'll probably save money buying one is you want the perfect footage.

Note: Sample footage and stills from our new DiGi35 static adapter will be available soon at www.digi35.co.uk.

Not bad, Riley. I can't beleiev that you actually pulled it off with such great depth of field. Was it time consuming to produce that effect. I'm thinking that if someone develops the right software/plugin to be able to reproduce good DOF, they are sitting on a pretty good chunk of change. Great job!
