Not aspect of the high quality Star Sequence, that lens carries a a lot far more modest price tag of $four hundred. The two lenses are advertised for out of doors pictures, a industry niche Ricoh-Pentax has concentrated on with rugged, climate-resistant digicam bodieseven on its entry-level styles.
