Originally posted by Culture Even before then I had seen a couple of threads here claiming this notion that their shots were not sharp
When the k-3 first came out there were a number of post complaining about the shots not being as sharp as the k-5/k-50 series. I had issues myself at first and from personal experience these are my conclusions:
1) The higher number of pixels requires better technique. Simply put, the k-3 is a bit like a sports car, things you got away with on the 16mp become noticeable on 24mp. Early reviewers ignored this or were not aware of it.
2) The sensor in the k-3 is different than the one used in the k-5/k-5II/k-30/k-50. We went a long time learning to process for that sensor family and the k-3 is different. Throw out your processing presets and start over. You will get much better results. I was not happy with my k-3 images until I did that, but the issue was my workflow not the camera
3) NR is different on the k-3. Whether that is the sensor profile, new algorithms or what I have no idea. But again forget what you knew from the older sensor and learn the new one. In my case I shoot only RAW so I just have NR turned off and deal with it in post. I also rare shoot at high ISO so I can do that. YMMV.
I have shot the k-x, the k-5 family and now the k-3 and in my mind I am starting to think of sensors not as something fixed but more like different films. You used different processing on different film stock, you need to do the same on different sensors.
