Hi all,

I've been lurking for a while and finally thought it would be worth while to bring back a discussion started by Richard Mellor in "parts list" thread
http://www.dvinfo.net/conf/showthread.php?t=37296&page=1&pp=15 thread
that pulls together info on making a static adapter with parts from thor labs, centered around this tube http://www.thorlabs.com/ProductDetail.cfm?DID=6&ObjectGroup_ID=213&Product_ID=1481

This thread ended without anyone posting a succesful use of this design on a dvx100. I am interested in seeing example footage and want to know if the use of two pcx lenses helps solve the need for two +10 diopters. In other words, what kind of magnification is needed for the original dvx100 (not A) to work with the thor labs style adapter?

Thanks for sharing.

Yeah, that looks great for a static adapter.
Clean look, but maybe a bit heavy?
I'd use something like this for a retail item.

I'm constructing it as we speak. I'll let you know how it operates on my GL2. I chose it because it seems so much easier to make than the other one (http://ideaspora.net/oldskool/). Eww, PVC and gluing. I'll take screwing things together any day.

Ben? You want to check your link? It isn't working for me - thanks - Grazie

. . yeah, looks like the URL has "crept" under the last bracket and "slash" - - oops! G

Funny, I wrote both that tutorial, and an update about using ThorLabs parts (http://www.dvinfo.net/conf/showthread.php?t=38622). People seem to want to reinvent the wheel a lot around here...

Let us know how that tubing works, especially with the PCX lense... my system uses the Achromat and has nearly no vignetting.

Jim - I'm passionate about achieving LESS DoF with my XM2 . . . Do you have any images of your truly straightforward device?

No moving parts? GREAT!

Best regards,

Grazie

. . When I mean images, of course I meant the "results" from your camera and setup ..

Thanks - G

Hey Grazie...

Check that thread I linked to above -- there's a series of images of the adapter in that thread. Also, here's footage (http://ideaspora.net/demo/shallowDOF.html).

JIM! You total STAR! !

First, tell me there is no sound with your vcclip .. . otherwsie I'm gonna need to look behind my amp and PC copnnections - HUH!

Secondly - when the figure is pointing to the wall I can see just HOW shallow the DoF is . . great.

Thridly, you are very very close to a subject . . Do you have any examples where you are something like between 10 to 20 feet away?

I quickly scanned your tute. I think even I can do this! Hah!

Oh yes . . er . . what happens when you put a WD on the fron of this "trunk" - silly question?

TIA,

Grazie

OK...

Added an update to my tutorial at the index.html page, so check that out before diving in to the tut. Here it is (http://ideaspora.net/oldskool/).

Secondly, what's a WD? Wide angle?

Thirdly -- for far away shots I have a few grabbed and up. Go here (http://www.dvinfo.net/conf/showthread.php?t=33489&page=18&pp=15) and scroll down to where I say I've posted some outdoor sunny shots.

Yes . .Wide Angle ..

Brilliant Outside shots. Just brilliant!

Love the " .. outside2.jpg" with the bloke starting to walk acrioss the street. - Have you got a JPG which has the DoF the other way around? Background "soft" and the foreground sharp? Again " . . outisde.jpg" is the other way around . . if you got one? Be nice to see the sharpness on something near - with the BG soft.

What an amazing setup!

Grazie

Well I'm glad to see this thread has brought together more links and info. Speaking of which, Graham the original links seem to work fine for me.

Jim, I certainly appreciate the work you and others have put into designing and posting tutorials on your adapters.

I started this thread primarily to see if I could find anyone using an original (non "a") dvx100 with a static thorlabs adapter setup. The dvx100 is terrible at close focus and i am wondering if the drop from its 72mm lense to a 52mm size is doable.

Ben

Jim!

Thank you for the link to the "small" MOV clip!

Downloaded in London .. you've answered the DoF qualities for me . .thanks .. and I'm truly inspired . .again.

I may be able to get the GG machined here in London - for a very short time I used to work in a commercial ophthalmic/optical lab. I maybe able to get the GG achieved. What spec is the finished "surface" in terms of what is needed? Is there such a thing I can "quote" at the lads on the bench?

Best regards,

Grazie

Havn't tried a wide-angle, yet. Though, given what I know of optics, so long as it is from the same lens group you've set your flange focal length to, it shouldn't be a problem.

Those are the only shots I've got up and around at the moment. Short of time around here, otherwise I'd post more. Sorry.

As for surface specs -- hmmm... dunno that one. But, finer frost than 3 micron is needed.

edit: oh, and yes -- no sound on that clip.
