Celestron says “ Never use this filter if your camera has an optical viewfinder.” Does that mean to not use it on a Nikon D500?
Asked by: Michael
Because the Nikon D500 viewfinder is looking through the lens that is filtered, it is safe to use the Celestron EclipSmart Universal Solar Filter for Optics 75mm to 100mm with your camera.

Could I put this on a Micro 4/3rds camera w/Flip out OLED display (and telephoto lens)??
Asked by: Mike
The Celestron EclipSmart Universal Solar Filter for Optics 75mm to 100mm, is technically too big a filter for most Micro Four Thirds camera lenses. If you had a lens that was as big as 62mm- 72mm filter mount , you could use the Celestron EclipSmart Universal Solar Filter for Optics 75mm to 100mm.You may need to use some gaffers tape to keep it in place.

Asked by: Michael
The outside diameter of the Nikon 200-500mm lens is too large to fit the Celestron filter. You can use this Haida instead: https://bhpho.to/38vHAQw

Asked by: Mike
The Celestron EclipSmart Universal Solar Filter for Optics 75mm to 100mm will fit on the front of the lens as long as your lens is between 75mm and 100mm in outside diameter. The filter would not be near the camera so it would not affect the use of the a flip screen.
