In today's rapidly changing optical technology, the technical evolution of the zoom lens, as an important bridge connecting the observation and recording worlds, has witnessed a great leap from manual operation to motorized control. This transition has not only greatly improved the ease of use, accuracy and durability of lenses, but also pushed related measurement and image acquisition systems to a higher level of development.

In the era when motorized zoom technology was not yet popular, manual zoom lenses occupied a place in the market with their unique advantages. Its main advantages include:

1、Intuitive operation: manual adjustment of the zoom ring allows the user to directly feel the change in resistance, resulting in more intuitive control of focus and magnification, which is especially important for certain scenarios that require fine adjustment.

2、No need for power supply: Not relying on an external power source, the manual zoom lens is suitable for a variety of complex environments, especially in areas where the power supply is unstable, the manual zoom lens shows greater adaptability.

3、 Lower cost: Compared with motorized zoom lenses, manual zoom lenses are usually cheaper to manufacture and maintain, making them more competitive in some projects with limited budgets.

With the progress of science and technology, the electric zoom lens with its excellent performance gradually replaced the dominant position of manual zoom lens. Its main advantages are reflected in the following aspects:

1、Precise control: With the motorized control system, users can easily achieve single-axis or dual-axis control with more precise adjustment of the multiplier, greatly reducing human error. This is crucial for application scenarios that require high-precision measurements.

2、Automation Integration: The motorized zoom lens supports communication protocols such as R232 or USB, which can be easily integrated into various measurement systems and image acquisition systems to achieve remote control and automated operation, improving work efficiency and system intelligence.

3、Improve work efficiency: With fast motorized adjustment and short response time, users can complete multi-magnification switching and adjustment in a short time, thus improving work efficiency.

4、Extend service life: Due to the reduction of direct human contact and mechanical wear, the service life of the motorized zoom lens is usually longer, which reduces the maintenance cost for long-term use.

Manual zoom lenses and motorized zoom lenses each have their own unique advantages and application scenarios. Manual zoom lenses still maintain a certain market competitiveness in specific areas due to their intuitive operation, no need for power supply and lower cost. However, with the continuous development of automation and intelligent technology, motorized zoom lenses are gradually becoming the mainstream choice in the market by virtue of their advantages of precise control, automation integration and high efficiency.

In the future development, we can foresee that the motorized zoom lens will continue to make innovations and breakthroughs in technology, providing more efficient and accurate solutions for measurement, image acquisition and other fields. At the same time, with the popularization of technology and cost reduction, the electric zoom lens will also be more widely used in various fields, promoting the development of the whole industry in the direction of more intelligent and automated.
