Pentax K-S2 Φωτογραφική Μηχανή DSLR

Η Pentax K-S2 είναι μια μονοοπτική ψηφιακή φωτογραφική μηχανή  με καθρέπτη και crop αισθητήρα στα 20 Megapixel. Παρουσιάστηκε τον Φεβρουάριο του 2015 και την ίδια χρονιά κέρδισε το βραβείο της TIPA  στην κατηγορία Best Digital SLR Advanced. Τα τελευταία χρόνια η Pentax κάτω από την ομπρέλα της RICOH μοιάζει σαν να ξαναβρήκε τον παλιό καλό εαυτό της. Τα μοντέλα της έχουν όλα αναβαθμισμένα χαρακτηριστικά σε σχέση με την κατηγορία τιμής που βρίσκονται. Το ίδιο και η Pentax K-S2 που στις πρωτιές της περιλαμβάνονται ότι είναι η πρώτη αδιάβροχη dslr και με σπαστή οθόνη σε τόσο μικρό μέγεθος, ενώ ακόμη και ο κιτ φακός που κυκλοφόρησε με την ευκαιρία της κυκλοφορίας της Pentax K-S2 , ο SMC Pentax-DA L 18-50mm f/4-5.6 DC WR RE με το αθόρυβο μοτέρ, είναι ο μικρότερος σε μέγεθος ζουμ φακός.
