- I've made a collection of screens of grade 5, 9 and 15 microns.
- They are recomended for DIY vibrating adapters.
- They fit in my JetSetModels leaf spring GG holder, the one that holds the Canon EE screens. VH57 Ver 1.1.
- Not certain about the other holders, haven't tested them, this is the only one I have.
£8 Per Screen. Each comes with a free bag of Aluminium Oxide,
so you can regrind your screen or grind new screens! Should be as much as you will need.
Screens are approximately 38mm x 25mm
I only have a limited number.

You will need to use a condenser to use this ground glass, I purchased quite a few lens from surplusshed, and found that the L7310 was an excellent lens. It is the perfect size for EOS extension tubes and almost totally eliminates the hotspot. Also of all the lenses i purchased it seemed to be of the highest condition and quality, compared to other lenses which were marked and scratched. You want to avoid marking you condenser lens; since it is very close to your focus screen blemishes will affect the image to a larger degree than marks on the achromat.
For some reason the lens is no longer listed on SS; but you can still get it by entering the item number (L7310 ) into the quick cart on the left.
To mount it in the EOS tubes I put one layer of electrical tape (half width) around the condenser, and using a lens cloth I positioned it in my EOS tube with the flatter side facing the GG (inbetween the achro and GG). You can place it between the SLR lens and the GG but at the moment it seems to work fine for me in this configuration. I will perform some tests to check which setup produces the better image and report back later.
These are the same kind of screen I use in my DIY adapter tutorial.
This clip was filmed with a 5 micron GG; using just house lighting, it would look a lot better with proper lighting; there is some slight vignetting on the shots with my 135mm lens, but the lens is f 2.8 and being used at night so I think it works very well.
Unfortunately both of my cameras are being sent for repair so i won't be able to make more videos to show the screens off. I originally made this video to show off my DIY adapter, but since my cameras no longer work i have to use it here.
The clip is on youtube, watch it in HD the encoding is really poor! [ame="http://www.youtube.com/watch?v=p8IIPRhYdUg&fmt=22"]YouTube - Quick DIY 35mm adapter low light test[/ame]
