The Yashica ML 50mm f/1.7 is a standard prime for the Contax/Yashica (C/Y) bayonet mount, introduced around 1975 according to reviewer testing notes. The C/Y mount itself was developed by Carl Zeiss in 1973 as part of the collaboration between Yashica and Zeiss that revived the CONTAX brand; it served both CONTAX-branded and Yashica-branded SLRs. The ML line was Yashica's higher-tier optical range, and reviewers note that most ML lenses were built to a very high standard by Kyocera, with construction almost identical to their Contax counterparts, while a small number of later 'C' models were made by Cosina. Yashica lenses of this era are strongly associated with Tomioka Optics, though a reviewer cautions that specific attribution can't be confirmed because glass was supplied by multiple manufacturers. The lens has a cult following largely because it is repeatedly compared to the Zeiss Planar 50mm f/1.7 in rendering and sharpness while costing far less, making it a well-known bargain among vintage shooters. No established nickname is evidenced in the reviews for this specific lens (note: the reviews discuss two different lenses in the family — an f/1.9 and this f/1.7 — and only the f/1.9 was described as having swirly bokeh 'comparable to the Helios 44 series').
สรุป: The Yashica ML 50mm f/1.7 is for photographers who want Zeiss Planar-caliber sharpness and neutral, accurate rendering without the Contax price tag. It is a refined, correct-rendering fifty — sharp, clean, and pleasant in the out-of-focus areas — rather than a swirly character lens (that trait belongs to the f/1.9 sibling, not this one). If your results disappoint, as one reviewer puts it, you either have a bad copy or you're expecting an Otus for the price of a Takumar.
ให้ภาพนุ่มและเรียบเมื่อเปิดรูรับแสงกว้างสุด โดยไฮไลท์จะเริ่มปรากฏเป็นวงกลมเมื่อหรี่รูรับแสงลงเป็นค่าที่แคบกว่า f/5.6 — เวอร์ชัน f/1.7 นี้ไม่พบลักษณะโบเก้แบบสวิร์ล
ให้การถ่ายทอดสีที่แม่นยำและเป็นกลาง เทียบได้กับ Zeiss Planar 50mm f/1.7
คมเฉียบบริเวณศูนย์ภาพตั้งแต่ f/2 และให้ความคมแบบ "Zeiss sharp" ที่ f/5.6
แฟลร์จะปรากฏเป็นแสงคมชัดเมื่อเลนส์ชี้ตรงเข้าหาดวงอาทิตย์ แต่การจัดองค์ประกอบให้นอกศูนย์กลางจะลดแฟลร์จนแทบไม่สังเกตเห็น
ให้ความคมยอดเยี่ยมทั่วทั้งเฟรม แม้จะด้อยกว่า Zeiss Planar 50mm f/1.7 เล็กน้อย
