Hello,
Fav EP:
Can only list one atm, the Vixen LV 8-24mm zoom, great optics coupled with great function. A high quality flexible plossl without ER issues.
Greg, in regards to the United Optics lens 100degree history, (I think Rover/Lunt/APM/WO etc), a good background write-up is available from astro-talks.ru. (the 20mm APM is reviewed)
