从近期日本最新款式的全自动相机看,为了提高相机整体的便携性能,追求相机镜筒及机身的小型化,甚至超小型化,已成为一种趋势。但这种小型化并不是以牺牲镜头成像素质和机身功能为前提的。事实恰恰相反,新颖单焦距镜头相机在确保小型化的同时,镜头成像素质要比以往相机有更高的水平;从机身功能看,新型相机也绝不比它的前辈逊色。此外,这类相机镜头的镜筒一般采取了与相机主开关连动的伸缩式设计,开合自如,在非拍摄的状态下,镜头不占外部体积,与相机机身浑然一体 以佳能“小霹雳”F—XL型和“小霹雳”SE型相机上的高像质单焦距镜
In recent years, Japan’s latest model of fully automatic camera to see, in order to improve the overall portability of the camera, the pursuit of the camera tube and the fuselage of the miniaturization, even ultra-miniaturization has become a trend. However, this miniaturization is not based on sacrificing the imaging quality and the function of the camera as a precondition. In fact, on the contrary, the new single-focus lens camera ensures miniaturization and the imaging quality of the lens is higher than ever before. The new camera is by no means inferior to its predecessors in terms of body function. In addition, the lens barrel of this type of camera generally adopts the retractable design which is linked with the main switch of the camera, which can be opened and closed freely. In the non-shooting state, the lens does not occupy the external volume and is integrated with the camera body. Canon Perak “F-XL and” Perak "SE high-quality single-lens camera on the SE
