Canon 6D ViewFinder Spot

[sakibnaz]

Hi All.

I suddenly observed a cracked type spot while I am watching through ViewFinder on my 6D. I have attached a picture from my iPhone and the spot is red marked. The spot looks very abnormal ... looks something like a spider 😞

I opened the Lens and give a swipe the mirror glass with microfiber cloth but still the spot is there.

The picture is Ok as its a problem of ViewFInder only.

Any suggestion?

Thanks in advance.

Regards.
