Focal was a house brand of lenses sold through Kmart stores. As the reviewer notes, they were consumer-grade lenses manufactured by several different third-party makers, meaning quality and optical formulas varied between batches. The Focal 28mm f2.8 is one such budget wide-angle prime aimed at cost-conscious buyers rather than professionals. Despite the humble origins, the sample described is built entirely of metal, feels solid, and has a well-dampened focus ring—qualities that some vintage shooters appreciate today. It carries no established community nicknames or jargon, and its appeal is largely that of an inexpensive, all-metal vintage curiosity rather than a cult classic.
สรุป: The Focal 28mm f2.8 is a budget, Kmart-branded consumer wide angle with an appealing all-metal build and smooth focus, but modest optics—soft wide open, muddy colors, and heavy flare. It's best suited to vintage-lens tinkerers who value mechanical charm and low cost over optical excellence.
สีถูกบรรยายว่าออกมาทึบเล็กน้อย
ภาพค่อนข้างนุ่มเมื่อเปิดรูรับแสงกว้างสุด (f/2.8); คมขึ้นเมื่อหรี่ลงเป็น f/5.6
แฟลร์ปรากฏชัดเจนและโดดเด่นเมื่อใช้ที่รูรับแสงกว้างสุด
รายงานว่าคอนทราสต์ดี แม้ภาพจะค่อนข้างนุ่มเมื่อเปิดรูรับแสงกว้างสุด
