I want to convert my Canon lens into a macro lens. I really need the contact pins to customize the ring so the aperture will work. But I can't find it anywhere.
Does somebody know the name of this contact pins and where I can buy one?
Oke after a lot of searching I found the items
1 x Lens Contact Assembly for Canon (part in the camera itself)
1 x Canon Lens Mount Repair Part (plastic mount of the lens)
1 x Contact Assembly with Flex for Canon Lens (part in the lens)
2 x rear lens cover
2 x camera body cover
The parts where around €85 in total. That is not what I was hoping for a few pieces of plastic.
The lens contact assembly from the camera and contact assembly from the lens are the most expensive. I will search for an alternative way to mod my lens. I am thinking about using my old floppy IDE cable and the rear lens covers to mod them that the pins of the IDE cable touch the lens contacts when put on the lens and the other side of the IDE cable touch the contacts in the camera when putting on that side of the adapter and cover. To bad the original parts are so expensive.
I think your best bet would be to purchase a EF extension tube that supports AF. This contains the contacts that contact the camera body and the pins that contact the lens. Just a case of disassembling and then soldering the floppy wire between the two parts.
I have been wanting to do the same mod myself for some time, but haven't got round to it yet. Have a look at the "Meike Auto Focus AF Macro Extension Tube for kenko Canon" for sale on eBay, which seems to be the cheapest AF extension tubes you can get. You could probably resell the two unused tubes to recoup some of your costs as well (if you didn't want them).
