Hi there, I've been reading this forum for a while now and have decided to sell my Nikon equipment for an OMD. My question to you is, has anyone here purchased any refurbished lenses from a camera shop in Amityville N.Y? I was looking at a Oly 12mm refurbished lens and it's approx. $150 cheaper than new. It looks like it comes with a one year warranty. Your opinions would be appreciated.
