If your scope has adjustable magnification, you’ll typically find a ring just forward of the ocular housing used for adjustment. However, on some scopes like Nightforce, the entire ocular housing must be rotated to adjust magnification (a reason I avoid Nightforce scopes). Adjusting the magnific...
The last step before digitizing is to focus accurately. I have found that autofocus only works reliably if the film is further away from the lens (which is not ideal because it leads to a frame that will need to be cropped in post-production). I recommend turning AF off and focusing man...
To calculate the field of view of microscope you need to know the eyepiece magnification, field number and objective lens. Once you have this information you can calculate the field of view of the microscope by dividing the field number by the magnification number. ...
entirely. Switch your lens over tomanual focus, then carefully turn your lens’s focus ring until you’ve achieved perfect sharpness. (For even better results, use your camera’s Live View mode to preview the image on the rear LCD and zoom in to check the focus at a high magnification....
