Canon Extension Tube EF25  type_Digital Cameras 3 is a compact gimbal

3 is a compact gimbal head that can hold up to 10lbs of equipment- not bad for a head that weighs just over 1

the legs are spindly and unsteady and you’re more likely to pinch yourself trying to push the legs back in than you are to get a steady photo when extended

but this is a pretty decent manual-focus zoom lens for the Nikon F mount

But image quality is very good
