Kowa Prominar 663 XD fluorite lens? (1 Viewer)

Hello,
Currently I am looking for a good spotting scope of about 65mm, I have noticed, among others, the model Kowa Prominar XD 663mm, which on a website said that I had fluorite lenses, I do not know if this model is really similar to its Big brothers Prominar 773 or 883 ??
Has anyone been able to try or use this model, and if so with what eyepiece?
In comparison with a good swarovski 65 HD model, would it be far below in relation to contrast and sharpness?
Thank you very much for your comments

Hi,

the 663 uses was Kowa calls XD glass and everybody else calls ED. The only current Kowa spotter using fluorite crystal is the 883/4 - and then there is the master lens which is very expensive and not really a spotter...

The 663 uses the same EPs as all the other small body bayonet scopes (TSN 600, 610, 660, old single digit TSN & 82SV). It is not compatible with 820, 770 and 880 series EPs.
The main gripe is the current 20-60 zoom which is ok but not more. The other available current EPs are a 30 wide (great) and a 25 LER (specialized use with very thick glasses or for digiscoping).
