and it extends easily for shooting

considering how much of a pain in the butt it usually is to use a 135mm lens on a rangefinder camera

Nikon M2 what kind of battery_Zinc Air and it extends easily forThe Nikon M2 is a 27. 5mm extension tube for manual focus F mount lenses. Though it was originally designed to provide 1: 1 magnification on the original 55mm f3. 5 Micro Nikkor and it still does! it'll fit any F mount lens. Worth noting: This tube does not preserve any automatic functions, including metering, so you'll need to stop down manually to determine your exposure. Some cosmetic paint wear, good function.
