Hard Cover for Nikon (D610) DSLR Viewfinder Kesler Koman
There are cases you need to cover the viewfinder during extreme long-time exposure on your DSLR, so as to avoid leakage of light. A simple card board will do the job too, but an easy-to-open cover is much better. There are built-in cover on those high-end DSLR, but not on my D610, that's why I have to make one.
To put the Hot-Shoe Mount and the Cover together, you need an M3 screw and a nut, the more you tighten them, the harder the cover flips.You may also apply a Matte Black Sticker on the Cover to reduce light reflection, if you are running out of Black filament like me.
