Nikon Z9 Mirrorless camera owners now have two sizes of oversized eyecups to improve their outdoor performance. Hoodman HoodEYE eyecups have been improving photographers’ outdoor performance by supplying oversized camera eyecups for over 15 years. We created the oversized eyecup product category to help pro photographers link their eyes to their cameras by comfortably sealing out ambient light from entering their viewfinders. We found that having a glare free viewfinder greatly reduced eye fatigue. Soon after our original HoodEYE eyecup new product launch, many photographers who had to wear glasses reached out to us to make an even bigger eyecup to wrap around the side of their glasses. So, we began offering special eyecups for our friends who need to shoot with glasses on. You can easily upgrade your camera eyepiece in just a few seconds with either the regular or glasses HoodEYE eyecup. Your Z9 has an eyepiece release button at about 7 o’clock below and left of the eyepiece. Press the release button and rotate your eyepiece counterclockwise. Next place the HoodEYE eyecup with the notch at 11 o’clock and turn to the right until the eyecup clicks in place. We have a great video below that shows you how easy you can upgrade your Z9 Eyecup. The self-locking mount keeps your HoodEYE on your camera. Regular and Glasses HoodEYE eyecups also rotate to accommodate right or left eye preferences. So if you need to use your left eye, just rotate the eyecup to the position you need. Hoodman is always thinking of ways to improve the products that we sell to our customers. All Eyecups we make are made of hypoallergenic silicon rubber for comfort and safety. Thanks in advance for supporting our efforts to improve your performance.
