JJCEyecup Eyepiece Viewfinder Eyeshade for Nikon D3500 D7500 D7200 D7100 D7000 D5600 D5500 D5300 D5200 D5100 D5000 D3400 D3300 D3200 D750 D610 D600 D300S Replaces Nikon DK-25 DK-22 DK-24 23 21 20 28

Overall, I like this eyepiece. It is comfortable and clips onto the camera snugly. The only problem is that it sticks out further than the original eyepiece and is pressed in by my camera bag. This causes the eyepiece to lose its shape. This is easily remedied by removing from the camera and dunking it into a cup of boiling water until it regains its shape. I now just remove the eyepiece before putting it away in the camera bag. This is not a fault of the eyepiece, just the limitations I have with space in my bag.

This one fits perfectly on Nikon D750. It does not block your tilting screen on the Nikon D750 for viewing purpose, which was one of my concern while ordering this product. You can take the tilting screen out without much hassle, but you cannot lift it up. You can tilt the screen downwards. When you have to put the tilting screen back in to its position, you will have to adjust the eyecup gently with your other hand, the rubber is very flexible for doing that. Highly recommend this product if you wear eyeglass. *The amount of light it cuts is just amazing and you can see everything more clearly than before (specially landscape photography) through the view finder after attaching this eyecup. Quality product. I will update if there is any other issues.

My innate tendency, and consequently preference, has been to compose through the viewfinder of my camera, but the eyepiece cup (DK-23) supplied with my Nikon, was not comfortable, nor accommodating to a wearer of glasses. In addition, the fit over the viewfinder was not tight or secure, and ultimately contributed to its recent loss; somewhere in the depths of an English wood.By comparison, this eyepiece cup is ergonomic, manufactured from malleable rubber- accepting of spectacles, and slides and locks over the viewfinder with a reassuring 'click'.I confess, I fail to comprehend why Nikon (et al) persist with the inclusion of their redundant style of eyepiece.

I'm going to give this 4 stars despite returning it. The reason I returned it was that that I thought I was getting an eyecup fixture that can be dismantled and different types of rubber eyecup fitted for use on my Nikon D750 like the First2savvv Premium Quality DLSR Cameras Rubber Eyecup. https://www.amazon.co.uk/gp/product/B073RCCMX1/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 which I was hoping to replace after the mounting broke and I wanted a replacement mounting. I chose the JJC version as JJC make great quality goods.However the eyecup on this version is permanently mounted and can't be dismantled. It fits my camera fine but it gave me no option to switch eyecups. I have knocked a star off because I didn't like the feel of the eyecup itself. It's said to be made of TPU rubber, whatever that is, which I found quite rigid and not very comfortable, otherwise I may have kept it.

Fits well and has certainly enabled me to use the viewfinder on my camera with glasses on. It is not very comfortable but I am getting used to how to position it. On my camera it sits just a little low over the touch screen which can be annoying if you want to open it while you have the eye cup on. Still a minor issue and overall a good product.
