Hello all,
I have an absolutely mint Alpa viewfinder for sale. It also has a custom mask for a 58mm lens with marks for shift and rise/fall. The piece is in as new condition with all original packaging, including the small allen keys that fit the viewfinder's screws.
I've both bought and sold a fair amount of gear on both this forum and the Large Format Photography Forum (same username), and you can certainly purchase with confidence that the item is as described.
$1150 with US shipping included.
