I have a K-3II and a K-5IIS. I ordered a Foto&Tech Wired Remote Shutter Release Control CS-205 Replacement for PENTAX 645Z, 645D, K3, K5, K5 II, K30, K50, K500, K7, K110D, K100D, K100D Super, K200D, K10D, K20D and it did not work with either camera. I do not know if I was sent the wrong model, but it looked exactly like what was in the picture of it on the web. I sent it back today, and was notified that my refund was approved (Amazon).
So, I have been looking at the
Vello RS-C1II Wired Remote Switch for Select Cameras RS-C1II B&H. Does anyone have any experience with this product? B and H seems like they know what they are doing, and I want something that works.
