For sale is my Graflex/Wollensak Optar 90/6.8 lens in Graphex shutter, with retaining ring. Shutter speeds 1/2-1/400, B and T. Speeds sound appropriate, though I've not tested them for accuracy. Glass is clean with no marks, front or back. Stops from f/6.8 to f/32. This lens will just cover 4x5, which is how I've used it.

Would like $75 plus shipping (via USPS small flat rate box), PayPal gift only, please.
These are not bad. I use one on my 6x9 Linhof Technika, where it could be mounted on a recessed lensboard, which allows ample shift on a 6x7 negative.
