1960年,日本ASAHI(旭·光学公司)试制成功了点测光模式的单镜头反光照相机,将其命名为“PANTAX SPOTMATIC”。该相机通过镜头测光(TTL),由于技术尚不成熟,缺陷较多,加之点测光使用复杂,故并未批量生产、正式上市。直至1964年,才定型制作、规模生产,仍以该型号“SPOTMATIC”命名【PENTAX SPOTMATIC(SP)】,而实际使用的是中央重点测光。此时的该款相机,技术已较成熟,操作简便,测光效果较佳,受到了摄影爱好者的追捧,得到了较好的市场反响(图1)。
In 1960, Japan’s ASAHI (Asahi Optical Co., Ltd.) trial production of spot metering mode single-lens reflex camera, named “PANTAX SPOTMATIC”. The camera through the lens photometry (TTL), due to technology is not yet mature, more defects, combined with the point of light metering complex, it is not mass production, the official market. Until 1964, stereotypes production, the scale of production, is still the model “SPOTMATIC ” name [PENTAX SPOTMATIC (SP)], and the actual use of the central focus of metering. At this time of the camera, the technology has been more mature, easy to operate, metering better, subject to photography enthusiasts sought after, get a better market response (Figure 1).
