|You can see the visual field of the naked eye observation of the microscope is the right picture|
Normally, a 1/2 inch camera and a 0.45-megapixel lens will be included in the kit.
In this case, the field of view will be as shown on the right.
With a connector len of 0.45 times, vignetting (shadow) does not occur at the four corners of the image.
In case you really want to get a wide field of view, if you attach a wide 0.37x relay lens (wide angle) to the 1/2-inch camera, it will look like the right picture.
* Slightly, ambient distortion occurs.
