TS Optics M48 Variable Extension Tube 17–23 mm

TS-Optics variable M48 extension — 17–23 mm

This M48 × 0.75 extension provides continuously adjustable spacing from 17 to 23 mm.

Adjustment

The three-piece design uses a long male-thread base, a connecting sleeve and a knurled counter ring. Rotate the connecting section to set length, then tighten the ring to lock it.

Optical train

It is a mechanical spacer for the usual 2-inch filter thread. Include its set length in the complete camera-spacing calculation; it is not an optical reducer or corrector.
