Still thinning the herd -- this is a Schneider 150mm f5.6 Symmar Convertible lens for 4x5 in a Linhof shutter with an image circle of 210mm. Remove the front element and it becomes a 265mm f12 lens. Shutter speeds from 1 second to 1/200th; they all sound fine but the 1 second setting hasn't been tested with film. There are a few very faint marks on the front coating, but no scratches, dust, etc. Nice and sharp to the corners at f11; extremely lightweight and tiny -- this lens will fit in any field camera folded that is out there -- Wista, Super Graphic, you name it. Takes a Copal 1 board (not included). Sorry, no caps available; just the retaining ring. Asking $150, payable via PayPal.
