Vivitar IC 101 Panorama brand_Calypso These Nikon filters are designedThe Vivitar IC101 is the one to get if you want your camera to always be squinting at you suspiciously. The "Panorama" format here is roughly 36x14mm on a standard frame on 35mm film, not several frames across, so this is no substitute for an XPan, but it's also 1 300th the price, so, yknow.
