DIY Vibrating 35mm Adapter Test

[wueric]

Hello everyone,
This is my first post here if I remember correctly.

http://www.vimeo.com/881630

These are some random tests of my Canon HV20 with a DIY 35mm vibrating-GG adapter I built. I got the vibrating-GG holder parts from Daniel's web site (http://www.jetsetmodels.info/products.htm). It works great. The GG used was Canon EE-A. The 35mm Lenses used were

Nikon 28mm-F2.8
Nikon 35mm-F2.8
Nikon 50mm-F1.4
Nikon 85mm-F1.8

all old school AI or non-AI ones.

Somehow the converted video's quality is not as good as I expected. I suggest you download the original AVI file (at the lower-right corner of the page). It looks much better IMHO and is only about 20MB.

Some screenshots:

Looks great what achromat have you got?

[wueric]

Thank you, Alex_MD. I didn't use any achromat since I can zoom in close enough and focus on the GG using the HV20 built-in lens.
BTW your Vimeo videos look amazing.

Hey man that looks pretty amazing! Really sharp and little vignetting.

Is there a chance we could see the adapter you made? I am very interested!

nice , which lens did you use for the second screenshot ?

[wueric]

It was the 28mm F2.8.

As for the vignetting, it's quite visible in the original footages when using wide lenses. I've done the anti-vignetting for some of the shots in post. For 50mm and 85mm it's not so obvious.

I'll post some pictures of my adapters later.

Wow, that is probably the best DIY footage I've seen so far. For the love of God, post pics of your setup and describe it in depth.

The adapter itself is not much to look at. Basically it's just a cheap extension tube for Nikon F-mount with Daniel's vibrating GG holder inside of it. I did find that the distance between the GG and HV20's lens is crucial. If too short you'll get all kinds of problems, like blurry image near the edges, barrow effects, chromatic aberration and the vignetting seems to be worse. If too long you can't zoom-in close enough and focus on the GG. I guess adding an achromat could further improve the image since you can place the GG further away, but I'm pretty happy with the result as is, and I'll stop the DIY/MOD and start to shoot something with it. Maybe I'll try the achromat some other time.

Hi Wueric,

I've done the anti-vignetting for some of the shots in post. For 50mm and 85mm it's not so obvious.

Which tool (and how) did you use fo anti-vignetting in post ?
