This belt is ideal for my Nikon F3. Out of curiosity, after reading the comment of a previous acquirer, I compared with that equipping my original Nikon Df: it is neither closer nor wider; it is the same length, ideal for hanging the unit around the neck (yes, I know, to the old, but I'm old). Now it is suitable for the D800 device type, without lens, accuses his 980 grams? No doubt, but I can not compare the F3 and Df being lightweight. Well, it is more expensive than the "no-name", but that is not the end of the world.
