Review on Pentax K-70 Black DSLR Camera with 18-55mm Lens Kit, APS-C Sensor by Siu Young ᠌

This line: K-30, K-50, K-70, just like Pentax K-S1, Pentax K-S2, has a fatal defect in the green Chinese solenoid (diaphragm drive). After some time (as soon as the warranty ends in the main), a malfunction of the aperture control solenoid often manifests itself and as a result very dark frames are obtained. The diaphragm just won't open. It is closed to the limit. Is always. The core of the solenoid is made by the Chinese from a different alloy, which becomes magnetized over time. Plus, instead of Teflon, they used a rapidly aging plastic. All together, this leads to a jammed core and a blocked diaphragm. The network writes that the solenoid can be replaced by taking it from previous models released before the K-30 in Japan. Chinese - green; quality Japanese - white. But the problem is much worse - the Japanese solenoid is no longer made. At all. Moved all production to China. They released cameras with a marriage, and then realized that they had ruined the entire series, but the factory is no longer in Japan! Therefore, some authors suggest looking for old Pentaxes of this series, released before K-30, to repair new ones. the correct made in Japan solenoid can be found in all DSLR Pentax cases from *ist D to K-r. Although it is easier to send Pentax by the forest and immediately buy a normal brand that does not have such a feature. I want to immediately clarify that in the Pentax K7 / K5 / K-5 II / K-3 / K-3 II / K-3 III line, a different diaphragm drive mechanism is already used - a stepper motor. Pentax is aware of this problem and continues to release a "surprise" hobbyist line.
