[AstroSylv1]

Quelqu'un a déjà vu ce zoom de chez Pentax ? Essayé ? D'après le site Ricoh, c'est le dernier arrivé dans la gamme, malgré le nom, assez différent du "XL" tout court...

Up to 8 lens elements in 4 groups. Fully blacked inside to minimize internal reflections

ED-glass elements that include Lanthanum glass, to minimize chromatic aberration and maximize well-balanced transmission

Extra lens elements to reduce spherical aberration of the human eye (the so called “black-out” effect)

Maximum usability and viewing comfort with 38-60° apparent angle of view

Eye relief at a comfortable 20mm, also eyewear users can have a comfortable view

JIS 4 weatherproof so well protected against wet (outdoor) conditions or night-time dew

Twist-up rubber eyecup
