It is
Nikon DX AF-P NIKKOR 70-300mm 1: 4.5-6.3GED
135
I also notice that if I use the live view it will take the pictures but if I try to use the eye view it doesn't take pictures.
But if I use the 50mm lens the lens looks clear and the pictures are cleared too? Why my 300mm lens is dark and telling me that the subject are too dark?
