JJC Eyepiece Eyecup Viewfinder for Nikon D850 D810A D810 D800E D800 D500 Df D5 D4S D4 D3X D3S D3

The package arrived on time as per notification when ordered.The eyecup is packaged in a clear semi hard plastic envelope, there is probably a technical name for it but I don't know what it is. There are basic instructions, with small photographs, to help with the eyecup fitting. My camera is a D500 so can only give my views based on this.Basically, close the eyepiece screen on the camera and rotate the existing eyecup anticlockwise to remove from camera. The new eyecup has plastic film covering the inner and outer surface of the glass, this must be removed before attaching it to the camera. Align the new cap onto the internal thread, this should be done carefully as it would be very easy to cross thread it or the internal body thread.Rotate the new eyecup clockwise until it starts to bite.The rubber bowl can be rotated seperatly to fit your shooting eye depending on your left or right preference.I haven't been able to use my camera yet so will report back when suitably tested but it did feel comfortable when I briefly tried it. I would say the rubber of the cup is of a medium softness, rigid but supple, if that makes sense.The above are my views you may agree or disagree.Update.I have used the above over the last few months and found it so much better than the eyecup supplied on the camera. The rubber has softened up and is quite comfortable. This is a good product, well worth the money.

Been meaning to get for awhile so all good

Yeeaaaa... okay, so it does the job, just. Fit wise, it is great, and attaches to the camera perfectly. And the view through is unhindered. But it does flit between being tight and loose with regards to where it sits and points (not talking about how it attaches; that is excellent), and so I often find it having rotated and sitting in the wrong position all by itself when I bring the camera up to my eye. This might not trouble you, and it is a small niggle, but I need it to stay where I left it, and so I will be replacing it with something else. For the price I feel my review is picky; but if it doesn't do well enough what it's supposed to do, then it has to lose stars. If you're not as picky as me however, this is a great bit of kit for the price.

This is a very simple piece of kit to block out unwanted light when using your camera while wearing spectacles. It's easy to fit to the camera. and, contrary to some of the write-ups, it's easy to turn when you want to use the camera from horizontal to vertical. The only slight quibble I have is that the rubber part of this eyecup could be a little thicker. Have used it twice so far and the eyecup has performed as it should.

I bought this eyecup for my Nikon D4S and it is perfect. It is easy to fit and very comfortable to use. Thoroughly recommended.

Fits and adjusts easy, cuts out any distractions.

Works fine for both eyes and easy to fit

When installing it on a Nikon D500, make sure you close the eye piece window, so that you can unscrew the existing eye covering.
