46mm ND2 to ND400 Variable Neutral Density ND Filter
Works great but has 360 degree rotation and conducts with lens hood
It works great on my 25 mm F1 .7 Lumix lens.Pros:Easy to install, simply screw onSimply twist the filter to desires settingHas Min and Max indicators with dots in the middle to designate levels of darknessCons:-Does not stop at Max or Min settings like other filters I have. It spins 360 degrees.-I can\'t use simultaneously with my lens hood. I have to put on the lens hood, followed by the filter, or... use the filter, with no lens hood. The lens hood won\'t fit over the filter.
