I just got word today I'm in for a $500 windfall..... a cash-only performance bond I posted 13 years ago is being refunded to me as it is no longer needed. NAS is a terrible disease that must attended to. My first thought was to pick up a used Nikon PB-6 bellows. Then perhaps a 24 or 28mm lens I can put on it in reverse. But I'm open to suggestions!
