Originally posted by Auzzie-Phoenix Tony, if you're a bit uneasy about a k-30/50/70, etc... there is always the possibilty of going with a used K-5II. The price would be slightly more than a new K-50, but less than a K-70. You may or may not be lacking some minor features, but it is definitely an option to consider, and it would be a natural progression up from your k-100d.
Well again, many thanks for getting this in gear. I did follow your instructions to the letter. Here is what I did: ( I did receive a slightly used k-50 body with only 305 shutter activations for XMAS 2016), I used my Takumar F 70~210mm lens with an A setting and the camera set at Auto Pict, @1/100s, F/4, ISO at 400 and using onboard flash. This shot came out beautifully. Then I switched the aperture ring over to f/5.6 with shutter @1/80s, ISO at auto from 100~800, with the camera set on Manual and used onboard flash. Nothing worked. I ended up having to use Program mode, used onboard flash and everything worked just fine. Very happy with the results. Now to switch tracks here and speaking only for myself, I believe that once Pentax became aware of the problem of Aperture Block Problem of such a grand scale, they should have said, "Okay, all bets are off, everyone who has purchased a Pentax k-30 and or Pentax k-50, send it in to us and we will make it good." These issues happen for only one reason and that is they were cutting corners to save money. I am aware that a company has a right to minimalize its overhead, but they should stop cutting corners until there are no more corners to cut. I am perfectly willing to pay for quality. There was an American television manufacturer by the name of Zenith. The company had a wonderful motto they used which is: "The quality goes in before the name goes on." Sure, they eventually got beaten up by the Japanese manufacturers and went out of business.
That is my story and I am sticking to it.
