What is the red dot of Pentax k-x?

This is not a defect, but there is no focus in the viewfinder, which means there is no indication in the viewfinder, because the center is usually used for focusing, so I know where it is. I don't know if you have ever used a SLR with an indicator before. If not, it's not a problem for you at all! Don't worry because you are not used to having instructions!

Ps: Answer on the third floor. Pentax KX can select any one of the 1 1 focus points. The only problem is that there is no specific focus indication in the view frame, so we can only estimate where it is! Pentax is also free to choose focus!

PS2: Hehe, I think what the fifth floor said is also necessary, but the tone is not very good! The landlord should go to the Pentax section of major forums to find out more, and you will understand after reading more!
