RAH said:Yes, I just bought a Pentax PF-65EDa body and a Vixen 8-24mm zoom eyepiece. The combination is very good. The eye relief of the Vixen is much better than the zoom eyepiece that is bundled with the PF-65 eyepiece/body package. And the total price is cheaper for the body plus Vixen.
John Fleet said:Unfortunately the Vixen zoom doesn't seem to available in the UK, so it may have to wait until the long promised holiday to the States! Just out of interest what kind of price is the Vixen?

£129. Here's the link...

I have a Vixen 8-24 zoom eyepiece (and the Pentax 65) and do not see much softness above 40 - i.e. it seems just about as sharp to me right to the top, although it definitely gets somewhat darker. I agree about the blackouts at the lower end.stuprice68 said:After using the Pentax for a few months with the "clone" zoom I've come to the conclusion that the zoom is perfectly useable but has its limitations. At over 40X the image becomes very soft and at 16-20X I often get "blackouts".
Tom reviewed the scope with the XF zoom. Has anyone used a Pentax scope with the superior Pentax SMC zoom?RedBishop said:I'm not sure if it was alreadt posted or not, I though this could be intresting for some:

Zack2 seems to indicate the performance of the clone/Vixen is fairly close so I probably won't bother upgrading to the Vixen zoom. I think I'll keep looking for a 6-21mm zoom eyepiece with decent eye relief (if such a piece exists that is). Or get a 6mm or 8mm wide angle to complement my 12mm XF. Eventually.
Leif,Leif said:Since the Pentax takes standard 1.25" eyepiece, you can use, or at least mount, the Leica zoom since Leica do an adaptor. However, I'm not sure whether it will give you the full focus range. You might lose infinity, or some of the close focus range. So it would be a case of suck it and see. I think the same comment applies to other zooms e.g. the Zeiss. The Leica is an excellent optic, but the Zeiss will give a wider FOV at low power.

Clearly, these are two different zooms from Pentax.
