We have a macro zoom lens with aperture control available at our company.

We’ll compare the differences in appearance due to the aperture

 

 

 

The shooting range is as shown in the above photo, but for a clearer comparison, we will enlarge and compare the red-framed area (including scratches, rough surfaces, and metallic surfaces)

 

 

 

 

1．Fully open aperture

The image becomes brighter and the resolution increases, but the contrast decreases

 

 

 

 

2．Stop down a bit

The image achieves a balanced mix of color reproduction, contrast, and resolution.

 

 

 

 

3．As narrow as possible.

The depth of field becomes deeper, but the resolution decreases

 

 

 

 

＜Reference＞

If you observe the same field of view with a medium magnification macro zoom lens, it will look like the following
