How
to Send in your 400mm f/3.5 Lens mount to be upgraded.
There are several steps involved in sending me a Nikon F lens mount to be upgraded.
First get a standard #0 Phillips screwdriver from your local hardware store. They are only a few bucks for a set. I'd also recommend putting a small amount of penetrating oil on the screw heads and letting it soak in overnight before attempting to remove the screw heads. If you somehow manage to strip the screw heads you will have to send the entire lens so I can re-groove the screw head and remove the mount.
Next
remove the five screws around the lens mount. If the screwdriver came with
a torque handle I'd suggest using it. It makes removing stubborn screws
much easier.
Next send
the removed mount to me at
Rolland Elliott

Charlotte, NC 28273
ph# 704 504-3528I will send
you back the mount with matrix metering chip attached.
Simply screw down the mount with the five screws you previously removed.
That's it. Go out and take some pictures!
