Pentax K-50 Φωτογραφική Μηχανή DSLR
Η Pentax K-50 είναι μια μονοοπτική ψηφιακή φωτογραφική μηχανή με καθρέπτη (DSLR) με αισθητήρα 16 megapixel που παρουσιάστηκε τον Ιούνιο του 2013. Είναι μια αναβάθμιση της Pentax K-30 που είχε παρουσιαστεί ένα χρόνο νωρίτερα τον Μάιο του 2012. Η Pentax K-50 με τον crop αισθητήρα είναι το εισαγωγικό μοντέλο στο φωτογραφικό σύστημα της Pentax και ενώ είναι σε αρκετά χαμηλή τιμή έχει αναβαθμισμένα χαρακτηριστικά που άνετα την τοποθετούν στην κατηγορία mid ή up-entry level. Ανταγωνίζεται δηλαδή φωτογραφικές μηχανές που είναι αρκετά ακριβότερες. Το κύριο χαρακτηριστικό που την κάνει να ξεχωρίζει είναι ότι είναι αδιάβροχη και από άποψη εμφάνισης ξεχωριστή την κάνουν τα 120 διαφορετικά χρώματα που είναι διαθέσιμη στην αγορά.
