at surplussched you need to look in category ACHROMAT not into LENSES.

Light Loss
 
Did some test today and it shows my adapter lose about 1 stop of light using Canon FD f1.4. That means the adapter itself will lose about half stop of light.

Where do the syringes come into play?

Quyen Le August 1st, 2005 05:49 PM

I will try to build one and take pictures with instruction today. The syringe parts was hidden in the new version, did not show in the pictures.

Quyen,

Instructions would be great, love to check it out against the one I am building!

New pictures
 
Below are pictures with instructions. I assume you downloaded the emachineshop.com software and view the 3 custom parts that I posted ealier.

Quyen,
Excellent work my friend. I think I speak for everyone when I say I really appreciate your hard work and time to share you design with these detailed instructions.

Perhaps we should all get together and source out online suppliers for the parts needed? Im in the UK and found suppliers of syringes and pager motors on ebay.

This is really coming along, keep it up.

Wayne.

Quyen,

WOW. Excellent tutorial. You are very resourceful.

Thank you very much.

Quyen Le August 2nd, 2005 10:47 AM

Thank you.

Making the guide is harder than making the adapter :)
There are a lot of parts out there thought to be better to use but I have reached the limit of my expense. I have spent well over $1000 for this project already. My intention is to make affordable commercial units. I have an challenge on this forum of making this product for $150 when I introduced my cup35 design, well, with better design and all the good stuff that add on to the unit, I think this unit worth more than $200, don't you think? I know that there are some of you enjoy making the adapter so much and you won't buy the adapter at any price, but there are still a lot of people don't want to get a hand on it but to get the professional looking video. Here is my offer, for the limitted of time, I will make this adapter for only $200. With all the measurements, calculations, I can only make 1 unit in 1-2 days. Macro lens/ condensers will be included in this adapter. I designed this one base on my vx2000 with 58mm filter size. If you want to use bigger or smaller filter size, you have to get the step up or step down ring yourself. I am working on an 72mm version now and will post it when it's ready. Thanks.

Quyen,

Those machined parts are awesome - do you manufacture rubber and plastic as your business from your home? Having the ability to do that is great!

Darnit, I can't find those grommet and syringes anywhere - Walmart has syringes, but they are not the right kind and Home Depot and the $1 store didn't have any - any ideas?

I am using a small toy motor that seems to give me pretty good results, but Quyen is right, you need the rubber to get proper vibrations. Also the aluminum case is a great idea because of the heaviness to stop the vibrations.

Quyen Le August 2nd, 2005 11:10 AM

The grommets, I bought at the local surplus store. The syringe parts, I got from my dad. Find some diabetic friend and ask them to save you some. I believe you know some people with diabetic.

I built my hobby plastic injection and all my molds at home here. I also have FD mount XL1 adapters, EF mount XL1 adapters, AI mount XL1 adapters and FD mount adapter for Canon L1 L2. All of them made right here at my shop. If I have to order those parts, I can noway to offer the $200 price for this adapter. I hope you enjoy my pictures and guide, thanks

Quyen,

So for $200, you'll sell me a box that I can screw onto the front of a GL2, attach a 35mm lens to the front and start shooting? How would you like me to pay?

Quyen Le August 2nd, 2005 12:17 PM

Paypal me quyentle@hotmail.com, thanks.

Now is it the rubber syringe part or the rubber grommets that allow movement? if the grommets are necessary for allowing more movement, would it be possible to use something less rigid than the syringe part to allow for more movement and then not have to use the grommets?

I just was thinking the adapter would be easier to make if it used the lowest possible power and size motor (maybe 1.5V for fewer cells?) and did not require grommets which seem possibly difficult to get since i imagine the rest of it could be made with a drill a small saw and some pvc/wood for those of us without injection molding plastic capabilities.

Also, I kind of liked the bead design in that the beads were quite short, an adapter with less depth might allow for interchangeable lens mounts (which i think could be very useful). Maybe even use a larger GG with interchangable mounts so people have the option of using larger format lenses for tons of shallow DOF. Your design has the lens mount built in, right?

Also, I imagine for those of us that have camcorders with removable lenses (canon XLs, homemade HD, etc) it would be easy to use extensions to increase the macro abilities of a lens rather than using macro +10s or +5s that have a lot of chromatic abberations and such. (maybe thats a topic for another thread)

I think your guide is really awesome, probably the first and only oscillating design I've ever seen with really good and simple directions that are freely available. I know its a lot of work to document such a process so everyone can have access to it and understand it, so I really appreciated the work youve done.

Leo Mandy August 2nd, 2005 12:26 PM

Injection molding? Sounds cool, where can I buy a device like that? Are they expensive kits?
