Originally posted by Pål Jensen very nicely built with a beautiful solid feel. It also very sharp at F:8. But expect to be more prone to flare than the best Pentax lenses...
Compared to many of the other 50mm lenses I own with an aperture of f/1.2 and faster the pentax lens is more resistant to flare than you think, especially when compared to voigtlander lenses. If you use an appropriate lens hood flare isn't an issue, however I will admit to rarely using a lens hood with mine - when you have been using a lens for over 13 years you
really get to know it.
Yes, the 50mm f/1.2 is extraordinarily sharp:
