Hi, I don't have Nikon equipment myself, but wanted to use this nice loupe on the R-D1. Sadly it doesn't fit. The DK-18 adapter is the wrong way around so it doesn't help either.
Both are new in box
Mounted on the finder, the loupe magnifies 1,2x.
Fits the series D2, D1, F6, F5 en F4.
Looking for 35 euros for the loupe, including shipping and paypal if needed.
The DK-18 ring is 10 euros.
