Nikon D70, Extension Tubes K2

Archived from groups: rec.photo.digital (More info?)

After mounting and using a K2 extension tube on my D70, I note in the
printed manual, "The following cannot be used on a D70... K2 rings."
And, the Nikon web site adds K1, PK-1, PK-11, BR-2, & Br-4 to the
prohibited list.

The only problem I noticed using the K2 ring is that the D70 does not
latch the K2 ring in place; it could rotate out of the mount.

Anyone know if the prohibition is based on anything more than this? Did
I damage anything I can't see?

FWIW, here's what I was doing:
- We don't want dust on the low pass filter...
- I wannt to use bellows and a macro lens... So...
- Mount K2, Skylight filter, another intermediate K-ring for spacing,
the final K ring with female bayonet mount, and then the bellows. The
various K rings connect with 52mm filter threads, so the skylight
filter fits right in the stack. The skylight filter creates a barrier
to any dust that's pumped in when the bellows is expanded/contracted.

Any thoughts?
