Can you add a close-up circle to the macro lens of insect photography?

Of course, even this method has advantages and disadvantages. Adding a close-up ring can enhance the close-up function. Not only that, but its price is relatively cheap. No matter how close the lens is, you can see it clearly, for one thing, you can observe and experiment better, and for another, you can be more direct and clear. Of course, it also has shortcomings, such as being clear at close range, but being far away, it will be found that it will take off the mirror and affect observation. Secondly, it is not easy to focus at close range, and low-end cameras are easy to produce purple edges. Try to use what suits you and try your best to play.
