New SG35 'Real Spinning Ground Glass Adapter' Commercial version coming soon.

Andy Gordon · May 20th, 2006, 05:44 AM

Looks pretty awesome Wayne. A little edge blur but no BD or CA. Would be nice if there was sound on it to hear how loud the motor is, esp with a hot mic like the rode videomic.

I guess those were all with the lenses fully open? I find bokeh tends to look a bit hazy with a fast lens fully open unless you have a high diffusing gg, but the price for that is more light loss. What is the grit finish on the gg? What is the light loss like? How high can shutter speed go before grain/flicker show up?

Cheers
Andy

Thanks for your comments, Andy!

All shots with the 28mm lens were wide @F1.8 as we had not tripped the lens to allow aperture control, however the shots with the 85mm and 75 -210mm zoom were stopped down a fair bit.

The lightloss from the SGpro is about 1/2 a stop. Note this does not include the light loss from the actual SLR attached.

Im glad you pointed that out. We found something new on the DVX, something we assumed different, and thats the DVX's tripod hole is actually off centre in relation to its lens, we had always assumed it was central! This was not a problem in the original SG35, since the support was left/right adjustable, however the SGpro support is not to keep it as rigid as possible. So the DVX was not aligned straight with the SGpro, hense the soft edge in 1 side. I will maching mounting holes offset 9mm ready for the dvx before shipping the units.

Just a tad above 1/500 s, but depends on shooting conditions, sometimes higher.

Hi Wayne,
Your adapter footage looks incredible. The detail in the clouds are so nice-that's something I haven't really been able to capture with the beta g35 (light loss maybe?) But the diffusion looks great, compared to the raw g35 footage I get. That footage looks like it has a lot of potential for color grading:) Do you have any footage with an xl2? I would love to see. 35mm adapters rock!

Thanks for the kind words.

Yes im meeting up with my XL2 tester next month!

Looks great! although, you forgot to flip the image horizontally, because the bus, was driving on the wrong side of the road, or something.

What brand of lens was the 28mm F1.8?

Aaron Koolen · May 20th, 2006, 12:36 PM

Wayne, definitely looking very nice! Well done.

Aaron

Cole McDonald · May 20th, 2006, 12:40 PM

Nice looking footage. Did you have a focus knob attached or just using the lens?

Wayne Kinney · May 20th, 2006, 12:46 PM

Thanks guys.

The 28 was a Sigma 28mm F1.8 aspherical MF (i love this lens).

Cole, if you mean a follow focus, then no.

Just re-read this...that's funny bill (assuming you're trying to be).

Very nice and sharp Wayne. There's noticeable fall-off in some of your sky shots (particularly top left) and more so with your 70-200 in the last shot. As you fade out it is very apparent. Is this resolvable in your opinion..or a reality of diffusers with slower lenses?

Wayne Kinney · May 20th, 2006, 02:02 PM

Dennis,
Yes the falloff and soft edge are due to the dvx not being aligned. The dvx's tripod hole is 9mm off centre, so I will machine new mounting holes on the sliding plate clamp to account for this.

Cole McDonald · May 20th, 2006, 02:21 PM

Do you know off hand how far off the XL mounting holes are from center of lens? I'm running into this same problem with my adaptor I'm making.

Wayne Kinney · May 20th, 2006, 02:27 PM

About 23mm
