Rare RICOH XR RIKENON 50mm F1.7 (Early Model: Made by Tomioka Optical) *Please be sure to read the profile.* [Product Features] While the specifications of "metal construction, minimum focusing distance of 0.45m" are the same as the famous "50mm F2 First Generation," which is called the "Japanese Summicron," this "50mm F1.7 Early Model" seems to have had more cost invested in its glass materials and coatings. "50mm F2 First Generation" → Monocoating "50mm F1.7 Early Model" → Multi-coating The image quality is characterized by sharp focus and a shallow depth of field, which is hard to believe for an aperture of "F1.7." Also, the blurring of the out-of-focus background has rich gradations and smooth transitions. This lens creates a sense of three-dimensionality.
