On the 6×7 format, its field of view is roughly equivalent to a 120mm lens on 35mm, giving photographers a classic portrait and short telephoto perspective with the image quality only a large negative can provide.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eMamiya's RB67 lenses are known for their sharpness, clarity, and smooth tonal transitions, and the 250mm f\/4.5 delivers the same professional rendering. The long focal length creates natural compression and pleasing background separation, which is particularly attractive for head-and-shoulders portraits.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eLike all RB67 lenses, it features a built-in Seiko leaf shutter with speeds from 1 second to 1\/400 sec. Because the shutter is in the lens, flash synchronizes at every speed, a major advantage for studio and outdoor fill-flash work.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eFocusing is handled by the RB67's bellows, which allows the lens to focus closer than many telephotos of similar focal length. The solid, all-metal construction reflects the professional studio heritage of the RB system, and the 77mm filter thread accepts standard large filters.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eThis lens excels at portraits, fashion, landscape details, and still-life work. Its compression flatters facial features, and its reach lets you isolate distant elements of a landscape for more graphic compositions.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eIt is compatible with the Mamiya RB67 Pro, Pro-S, and Pro-SD, and can also be used on the RZ67 with manual shutter cocking. With a suitable adapter, it can also be used on some digital and mirrorless cameras, where it becomes a characterful long telephoto, although the leaf shutter must be held open for adapted use.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eMedium-format film photography has seen a strong revival, and the RB67 remains one of the most accessible and capable systems to enter it. A good telephoto lens like this 250mm is an important part of building a complete RB67 kit.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eIf you are looking to expand your Mamiya RB67 system with a high-quality portrait and telephoto lens, the Mamiya-Sekor 250mm f\/4.5 is an excellent and highly rewarding choice.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n \u003cdiv style=\"color: rgb(44, 62, 80); font-family: Arial, Helvetica, sans-serif; margin-bottom: 24px; background: linear-gradient(135deg, rgb(244, 249, 255) 0%, rgb(232, 242, 252) 100%); border: 1px solid rgb(207, 224, 241); border-radius: 10px; padding: 18px 20px;\"\u003e\n \u003cdiv style=\"font-size:20px;font-weight:bold;color:#173b63;margin-bottom:8px;\"\u003e\n Specialty Store for Used Cameras \u0026amp; Lenses\n \u003c\/div\u003e\n \u003cdiv style=\"font-size:15px;line-height:1.9;color:#42586e;\"\u003e\n We are a Japan-based specialty store focusing on used cameras and lenses.\u003cbr\u003e\n Our items are carefully inspected and described as accurately as possible for international buyers.\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003cdiv style=\"color: rgb(44, 62, 80); font-family: Arial, Helvetica, sans-serif; margin-top: 30px; text-align: center; padding: 20px 10px 4px; border-top: 1px solid rgb(214, 228, 240);\"\u003e\n \u003cdiv style=\"font-size:18px;color:#173b63;font-weight:bold;\"\u003e\n Thank you very much for your understanding.\n \u003c\/div\u003e\n \u003cdiv style=\"margin-top:8px;font-size:13px;color:#6f8dad;letter-spacing:1px;\"\u003e\n Peekaboo Japan       \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\u003c\/div\u003e","brand":"Mamiya","offers":[{"title":"Default Title","offer_id":50521533251722,"sku":"20261011JPY","price":135.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/2977\/4474\/files\/s-l1600_dc36d45e-504b-49ce-8c2c-e09857d15acf.jpg?v=1792511082","url":"https:\/\/peek-a-boo-camera-japan.myshopify.com\/products\/w-capmamiya-sekor-250mm-f-4-5-telephoto-lens-for-mamiya-rb67-japan-e0527","provider":"PEEK A BOO CAMERA JAPAN","version":"1.0","type":"link"}
