专业照相机的可靠性主要体现在其设计的合理性(包括机械动力学性能及相关电子电路和执行机构)、耐环境、抗老化性能,以及在正确的使用条件下以零或极低的使用故障率来保证一个较长的合理的使用寿命。 另外,绝大部分专业照相机生产厂家都把抗一定的误操作及非正常使用、保管可能带来的相机损伤,作为一项独特的富有专业相机特征的设计,融入自己的顶级专业产品中,例如尼康F4上可交换取景器的外壳由合成材料制造,但在专业人士反映其在不正常操作
The reliability of professional cameras is mainly reflected in the rationality of their design (including mechanical dynamics and related electronic circuits and actuators), environmental resistance, anti-aging properties, and under the correct conditions of use with zero or very low failure to use Rate to ensure a longer reasonable life. In addition, the vast majority of professional camera manufacturers are against certain misuse and abnormal use, custody may cause damage to the camera, as a unique feature-rich professional camera design, into their own top professional products, such as Nikon F4 interchangeable viewfinder shell made of synthetic materials, but in the professionals reflect its abnormal operation
