Leotax T + Konishirorku Hexar 50mm f3.5 + AGFA vista+ 400 film Test (expired 10 yrs.) 過期10年底片測試

2025/3/22

The first thing that caught my attention about the Leotax camera from Japan's Showa Optical Works was its name — it sounded like a combination of LEica and cOnTAX. The Leotax T in my collection is a Leica-style rangefinder camera using the M39/L39 mount, released in 1955. At that time, three models were introduced: the F, T, and K. The main differences lay in their shutter speeds: the F had a top speed of 1/1000s, the T topped out at 1/500s, and the K further omitted the slow speeds below 1/25s — effectively making them high-end, mid-range, and entry-level models, respectively.

我第一注意到日本昭和光學的 Leotax 相機,是它的名稱很像是LEica+cOnTAX的組合。手邊收藏的這台 Leotax T 是1955年上市的仿Leica M39/L39的測距對焦相機,同時期上市的有F、T、K三種型號。主要的差別在快門速度,F最高快門為1/1000秒,T最高快門為1/500秒,K則是再移除1/25秒以下的慢速快門,剛好就是高中低階三款。

The Leotax T came bundled with the Hexar 35mm f3.5 collapsible lens, made by Konishiroku (the predecessor of Konica). It likely uses a Tessar-type 4-element, 3-group optical design. The image quality is solid and sharp, with vivid colors. Even when used on a digital camera, the lens continues to deliver pleasing color and sharpness. Below are a few test shots. The film used was AGFA Vista Plus 400, which had been refrigerated and expired for 9 years and 4 months.

Leotax T 搭售的鏡頭是Konishirorku小西六(Konica柯尼卡前身)的 Hexar 35mm f3.5 可縮藏入機身鏡頭,應該Tessar的四片三群結構,成像很紮實,顏色有很鮮豔,及使用在數位相機上,色彩和銳利度仍是非常討喜。以下是幾張測試照片,底片是冷藏保存過期9年4個月的 AGFA vista plus 400。
