Nikon DR-5 Viseur d'angle D700/D35

The device is optically superb, as indeed it should be at the price. My only gripe - and I knew about this before I bought it - is that fitting it to the camera (D810) involves unscrewing the eyepiece bezel on the camera (and keeping it safe), screwing on the adaptor, and then screwing the right angle viewer onto the adaptor. This is immensely fiddly, and something you would only do as part of a dedicated session of macro work, astrophotography or whatever. The camera should be ready to receive the viewer and it should just snap on; the actual arrangement is in my opinion a design flaw (in the camera - it's not the viewer's fault, hence my 5 star rating).

Terrible. Expensive and takes far too long to put on and take off the Nikon d500. Steer well clear of this is my advice.

It does what it needs to do.. BUT.. A lot of photography is about practicality and efficiency and this is neither. Its a night mate to screw on and screw off meaning if you need it RIGHT NOW or youll miss the shoot. Then forget about it. The thread is also really thin meaning if it was to be bumped prepare for a decent damage bill. The DR-6 and the Canon variant is so much better where you just slide it on and away you go. This screw on design is just so flawed...

Brilliant, this eyepiece is razor sharp and will prevent a lot of neck strain whilst working low to the ground; I can see a lot more functionality from it too.

Works well, fairly easy to install (but don't lose your regular eyepiece when you take it out!). 1 star off because of the price. It is big $ for what it does.
