A CHIP of the old lens

[DonSchap]

I am looking to "chip" my three Samyang lenses (800mm f/8, 85mm f/1.4 and the 8m f/3.5) and wondered what would be the best way to go about this. They are not M42s ... but true SONY/Minolta A-mount lenses.

Any assist to be found?

Thanks

I think on the front page of dyxum there is contact info to a guy that has programable chips I don't think there is a spot in the chips avalable choices for 800mm though I'm pretty sure I would remember that. he might in the end be able to help.

On the shorter newer samyangs isn;t there a spot marked on the mount or the remnents of a mold plg to locate the chip in? should be easy enough to machine the recess dfor it as long as the angle is correct there might already be clearance for it to begin with

Use James Lao chips, and get the stubby little version with the chip under the board. Do not get the version I did with the long circuit board and the chip positioned so you have to cut into the bayonet.

Basically, order this same chip with 8mm, etc focal length for each lens as needed.
