{"product_id":"usemamcser250f63tlr-u8","title":"Used C-series Mamiya Sekor 250mm F\/6.3 | TLR Lens | U8","description":"\u003cp\u003eThe Mamiya-Sekor 250mm f\/6.3 is a specialized vintage telephoto lens built exclusively for Mamiya's iconic C-series interchangeable dual-lens reflex (TLR) medium-format film cameras. Serving as the absolute telephoto limit of the system, it is highly prized for tight portrait compression, isolating landscape patterns, and pulling in distant street elements on 6x6 roll film. Because Mamiya TLR cameras lack a shutter in the body, this lens module houses its own entirely independent Seiko mechanical leaf shutter. While its slower f\/6.3 maximum aperture demands decent lighting for bright viewing framing, the optics deliver impressive contrast and sharp, warm rendering when properly maintained. For film enthusiasts, it transforms a standard twin-lens setup into an incredibly capable long-reach studio or field kit.\u003c\/p\u003e","brand":"Mamiya","offers":[{"title":"Default Title","offer_id":42873917374510,"sku":"USEMAMCSER250F63TLR-U8","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2657\/1868\/files\/e0ed1558-3133-4001-b341-4729b9579841.jpg?v=1793287194","url":"https:\/\/kmcamera.com\/products\/usemamcser250f63tlr-u8","provider":"K\u0026M Camera","version":"1.0","type":"link"}
