Anyone selling 35mm adapter?
Hey guys, I don't have the resources to build a 35mm adapter. So I am looking to buy one. I have a GL2.
If no one does, can someone point me in the right direction for building? I looked for a straight "tutorial" but I can't find a solid one for GL2? also recommendations on what macro lens to buy for this? Thanks. |

I'm putting together a kit for people that don't want to build them. You can check out the first prototype here:

I have my old tutorial over here, but will be updating it soon, so it's not officially linked from my mainpage yet. This is for the GL-1, but should work the same for the GL-2 -- they've got the same lens dimensions, I believe.
Good luck! - jim

James,
Can you demonstrate what a pan looks like with your setup? If you're short on space, I'll host the file for a bit... - jim

Here is a link to a pan i'd done a while back. I had a shakey lens on it. Sorry about the compression or the lack of...

No need for the compression apology, I'm posting full res NTSC DV on my sight :D Each 25 second clip is about 50mb!
'sides, you need "uncompressed" video to see the true performance of a given setup, so the higher res the better. - jim

hi everyone I don,t mean to rain on the parade . but the static adapter is realy easy and cheap to make. the parts list . a c -mount adapter $35. 5 empty filter rings $4 each .plcx $22.
ground glass diffuser 1500 grit $14.cannon 1.4 50mm $60 and that's not a hot spot in the link. it realy is the light on the wall http://www.dvinfo.net/media/mellor/35%20mm%20lens%20test%202.jpg http://www.dvinfo.net/media/mellor/35%20mm%20lens%20test.jpg and james your setup looks realy cool. |

Richard,
Things are dry around here -- and you're late for the parade :D Where's the footage from your adapter? Can we see a 720x480, 30fps NTSC DV pan? This is the litmus test -- my adapter, made with specs similar to what you describe shows grain, especially in the highlights (see my old tutorial, which has 1000 grit AO, my latest uses WAO5). For NTSC viewing, web content -- i.e. output with even mild compression -- the WAO5 gg adapters are more than adequate. For projected material, the solution falls a bit short... - jim

1500 grit
hi jim did you ever try to use 1500 grit ground glass from a optical company. this is a link. the 2inch round glass will fit perfectly in a 52mm lens filter
http://www.thorlabs.com/ProductDetail.cfm?&DID=6&ObjectGroup_ID=1132&Product_ID=36117 the next step is to build the next one in this tube. looks more professional ,and with adjustable rings you can get the focal distance from the lens to the ground glass perfect. someone somewere pointed out this can,t vary 1mm or we will lose sharpness http://www.thorlabs.com/ProductDetail.cfm?DID=6&ObjectGroup_ID=213&Product_ID=1481 |

If I'm not mistaken, 1500 grit and WAO5 are the same, and if not -- I'm given the impression that WAO5 is finer. Otherwise, there's 3 micron grit around, but as I understand this acts more as a polish than an effective abbrasive.
At any rate, the proof's in the footage. - jim

Richard could you perhaps label the pieces in the photo you provided? I'm interested in how you put the thing together (specifically I'm looking to maybe adapt the design for a DVX...)

static adapter parts
I just ordered the parts if you want to save money you can wait untill i build this. the3 parts are sm2l20 ( 2 inch tube $29
sm2rr (2) @ $9. I haVe a 50mm plcx and i will be getting the 1500 grit ground glass $14 the system starts with cannon lens next c mount next tube fit the ground glass untill sharp focus plcx last .tighten down with sm2rr inner ring . heck this is laser stuff it,s made to be precise . I am just shy of sharp focus with the filter rings model I will say this I have tried every homemade ground glass all grit s and the ground glass from optmo sigma was by far the best yet. I cracked the ground glass and will now be trying thorlabs 1500 ground glass it,s even cheaper than optmosigma let you know how it looks next week sent chris a few stills will link to them when they show up this is the inner retaing ring. it can be threaded to any focal length. click links to stackable tubes of varing lengths http://www.thorlabs.com/ProductDetail.cfm?DID=6&ObjectGroup_ID=848&Product_ID=1483 |

When you get it together, if you need a place to host the file, I'll do it -- make it a 30 second NTSC DV pan in daylight, across various light/dark/vertical/horizontal objects... - jim
