[Profiler (Profiler)]

I agreed the Pentax XF's are easily one of the best eyepieces around - period (taking into all factors of cost, ER, FOV, optics etc).

The infuriating aspect about them is that there are only two sizes a 8.5 and 12.

The moment they make a 3mm, 4mm or 5mm Pentax XF I will buy 3 of each
