Hi, I'm Mike Padgett.
Today we're talking about this lens, the Vivitar 800mm F11 Solid Catada Optic Lens,
and mounting it to the FS100.
This lens was originally designed for the US military by Perkin Elmer, and is a solid
glass design, with no spaces between the front mirror, the rear mirror, and the reflector.
This T-Mount lens is 3 inches long and weighs about 3 pounds and has its own tripod support
mount.
My mother bought this lens new back in the late 70s to use with her Olympus OM2.
It is now mine, and I've decided to mount it to my FS100, making it an effective 1200mm
lens.
Since it is a T-Mount lens, I'm using a NovaFlex T2 mount to E-mount adapter.
Weighing in at 3 pounds, I didn't want this lens hanging off the front of the FS100, nor
did I want the FS100 hanging off the back of this lens.
Both of these situations put too much stress on the E-mount.
The bottom of the FS100 is not on the same plane as the tripod mount of the lens, so
I need an adapter plate.
I'm using the Manfrotto 577 Rapid Connect adapter as the starting point for my solution.
When I mount this adapter to the bottom of the FS100, there is only a small difference
between the two mounting planes.
To measure this difference, I mounted the lens to the camera using the T-Mount adapter.
I mounted the 577 to the bottom of the camera, and I turned the camera on its side so I could
see the true difference.
I had an adapter plate made with an offset that compensates for this difference.
I'm concerned about this plate flexing, so I'm using a 501 P-long quick release plate
again from Manfrotto on the bottom of my plate to mount this setup to my tripod.
Since the lens has to rotate to mount, you need to mount the lens to the camera and then
slide this plate on and lock it down.
This is how it goes together, and here is some video taken with this setup.
I hope you find this helpful, and thanks for watching.
