Brought these to replace 25 year old vivitars whose rubber coating had gone sticky. The Olympus are better made, clearer optics, and weigh pretty much the same. As an occasional user, I see no point in paying any more. I am very pleased with this purchase.

Terrific value
Good quality analogue meter at an incredible price. I have fitted volt and amp meters from this range to my variac - they work very week, and look good. Also easy to fit as they just need a circular panel cutout, and holes for four mounting screws.
Needed a correction lens for my Olympus OM2 film camera. These are very rare, but after some Googling I picked up that these Nikon lenses will fit Olympus OM film bodies. I can confirm that this is correct.
When selecting a lens make sure that you use your eyesight prescription for distance vision. If you use you reading glasses prescription you will make things worse.
I chose the lens by measuring the distance at which I could read a page of text with maximum clarity. This turned out to be ~500mm. The strength of lens is then the reciprocal of this (in meters) - i.e. 1/0.5m = 2D. As I am short sighted, I needed -2D.
