I think you have an ED60 ii already? If so the 20/30/38x should be perfect and I think the fact it states the ED50 magnification shows it has new (newest?) coatings. Others may be able to confirm that point. I guess you then compare the two scope bodies and sell the copy you like least, probably easiest sold with an eyepiece though.
This eyepiece is actually on my “want list”, to complete my magnification set (I actually have a WTB post in the forums with no responses), although I use an ED50 and ED82. On both of those I usually use approximately 30x (27x on ED50 and 30x on ED82) and I think that is considered the sweet spot for magnification on these scopes. See
This thread for some details of people using the eyepiece with the various bodies.
I would suggest that this eyepiece comes up pretty infrequently, especially on it’s own. My latest acquisition was a 75x DS and I paid £89 but I would suggest the 38x MC is a lot more desirable and therefore worth more.
Nikon UK advised me last summer the only current eyepieces are as follows, with their RRPs…..
- 40x/60x/75x Wide DS eyepiece: RRP £309.00;
- 40x/50x Wide DS eyepiece: RRP £309.00;
- 13-30x/20-45x/25-56x MC Zoom eyepiece: RRP £229.00;
- 24x/30x Wide DS eyepiece: RRP £279.00.
