Pentax K-70 Φωτογραφική Μηχανή DSLR

Η Pentax K-70 είναι μια μονοοπτική ψηφιακή φωτογραφική μηχανή με καθρέπτη, που διαθέτει crop (APS-C) αισθητήρα στα 24 Megapixel. Ανακοινώθηκε από την Ricoh τον Ιούνιο του 2016 συνεχίζοντας την πολύ πετυχημένη σειρά αδιάβροχων μοντέλων DSLR της εταιρείας που είχε ξεκινήσει με τις Pentax K-50 και Pentax K-S2. Συνεπής στο πνεύμα της Pentax, η K-70 προσφέρει αναβαθμισμένα χαρακτηριστικά σε σχέση με την κατηγορία τιμής που βρίσκεται και έτσι την κάνει και αυτή ιδανική φωτογραφική μηχανή για να μπει κανείς στο φωτογραφικό σύστημα της Pentax. 100% κάλυψη εικόνας στο σκόπευτρο, 102000 ISO και πιο γρήγορη ταχύτητα 1/6000 δεν τα συναντάμε συνήθως σε φωτογραφικές μηχανές σε αυτή την κατηγορία τιμής.
