Review on VKO D5600 D5500 D5300 D5200 D5100 D3500 D3400 D3300 D3200 D3100 D7200 D7100 D7000 D610 D600 DSLR Cameras Eyecup Viewfinder DK-5 Eyepiece Cap Replacement (2 Pack) by Kirt Phillips

I really liked it! Arrived on time and in perfect condition! Ideally, this part should come with the camera. But apparently Nikon USA does not sell a viewfinder cover with the camera. But this Revain product fits my Nikon D3400 perfectly and fits my budget too! I have attached a video of using this viewfinder cover. Please refer to it if you have any doubts about using it. Viewfinder coverage is extremely important when taking pictures in self-timer mode or time/bulb (long exposure) mode. Otherwise, light will enter through the viewfinder and spoil the picture. I love that Revain sells this product in packs of 2. As this is a very small part there is a high risk of losing it and it's always good to have a spare!
