Working DIY adapter

I have some test images from my 35mm adapter, It's a static adapter and I used it with my Canon XM-2. I think it's works really good but I really would like some feedback on it!

The skateboard clip is definitely the most effective small-DOV footage I've seen on this board. At first I thought you used Dan's (God all-)Mighty FOLLOW FOCUS, but some slight shakes on the end of a focus gave it away.

What frame rate is it? Or is it a built-in flicker effect? Anyway, it looks very good and reminds us what the heck we are doing here...

Ok, here is the parts:

thorlabs.com:
1p 29.50 EUR SM2L20 Stackable Lens Tube
2p 9 EUR SM2RR Retaining Ring For 2" Optics

optisigma
1p 26,20 EUR Groundglass, p/n 099-0160
1p 35,20 EUR BK-7 Plano Convex Lenses 011-2870


1p Macrolens
1p Stepupring


Nikon Lens > Nikon f-mount > ground glass > Plano Convex Lens > step up ring > +4 macro lens > Camera

I build the f-mount with an old f-mount from a camera and a 52mm filterring, glued toghether.

I'm waiting for Nikon BR-3 adapter to use instead. Everything cost me about $200-250 excluding Nikon lenses. I also need a better macrolens. Anyone knows where I can find a +10 diopter?

All clips are CC but no other effects. It's 25fps and I think the flicker comes from flash. The focus is set manually, it's difficult with the SLR lenses but with some practise it works quite well.

Jimmy,

How did you light for the side view shot of the camcorder with adapter? Did you use a white background or was the background purely photoshopped out? It looks very nice.

How about a +7 diopter? Ben winter is very pleased with the one from Century Optics

Thank you for the BR3 tip and all the other parts listed. I totally agree with what Oscar said a couple of posts earlier.

Jimmy,

Looks quite normal, but you are getting very good results. Do you need a spanner wrench to adjust those retaining rings?

Some have used the Hoya +10 macro lens.

No, I don't have any spanner wrench, I used a nail and my fingers.

Looks Great....

How's that tutorial coming along?

Also, noticed that your first clip (first version of the adapter) seems to be more sharper that your two newer clips (which seem to be a bit more hazy, but still quiet nice). Any guess why? (or is it just my monitor?)

I'm ordering the parts, but will try some diffrent options based on other threads,
such as adding a second pcx to make a sandwich - (| || |) - (pcx, gg, pcx) and adding another inch between the gg and the lens.

In your design, how is your pcx install || (| or || |) (curved side facing in or out)?

Thanks

I have no condensorlenses in the first clip but i had some vignetting problems then. I put the lenses like this:

I'm going to build the new version of the adapter during christmas and will try some different options. I haven't read about the option you are going to build, it would be nice to see some examples later!

I have a white background and a 1000w lamp. Then I used some curves to get better contrast in the picture.

Some new parts have arrived, going to build the new version before christmas!
