There were some small dust inside my camera It annoyed me so much that i tried to be a hero and try cleaning it myself. Bought a cleaning kit from amazon.jp, brushed it off, and… BAMMM!!
There you go! Smudges all over the whatever-the-hell-the-glass-surface-is-called. Like a rat repairing a pumpkin. huh! Luckily there’s no visible scratch whatsoever. Plus the image sensor doesn’t seem to be affected too, so i guess it’s OK. For now. I think I’ll be cursing a lot when I use the viewfinder in the future.
