It's hard to choose. How to choose a7m4 lens?

This depends on your specific use. For home use, I recommend the combination of zoom and certain focus, 24- 105 daily hanging up, and 85 special portrait shooting. If you don't think it's enough in the future, you can change a cost-effective deputy factory lens. Anyway, there is no need to pursue the performance and stability of the equipment too much at home.

If it's for work, choose gm lens. Of course, usually one shot is not enough. Other gm lenses are likely to be equipped in the future, and the auxiliary factory is not optional. However, the work is usually based on the original factory, or two cameras, the main machine is equipped with the original factory, and the standby machine is equipped with the auxiliary factory.
