One down, one to go

I was using my camera recently when I noticed that no matter how I focused, the images in the viewfinder were blurry. Wiped the lens. It did not fix the problem. Wiped the viewfinder. Still no luck.

It was then that I recalled that there was this feature called the diopter adjustment which allowed one to adjust the focus of the viewfinder. Also learnt that it works only on the viewfinder. The video display is as it is.
