This comment echos complaints from new K-3 owners when the 24Mpx sensor first became available. Those migrating from 16Mpx Pentax bodies were often not happy with image quality (sharpness mostly) and felt that the camera design was at fault. The standard response was that the extra sensor resolution makes greater demand on both optics and technique. If a user persisted that both lenses and technique were flawless, a common suggestion was to down-sample the 24Mpx image to 16Mpx and see if it looks better.
To elaborate:
- Attention to focus will pay a quality dividend
- Use a tripod when quality is a concern and when on-tripod use the delay timer or a remote shutter release
- Don't expect a flimsy tripod to hold the camera steady
- Don't expect the SR feature to make up for shaky hands
- Be aware of shutter speed and aperture. Avoid slow speeds and shooting wide open.
- Lenses that used to be good enough at 16Mpx may not deliver adequately at 24Mpx
If those instructions sound a lot like old school photography, that is because they are old school. Nothing has changed where critical work is concerned.
If one remains unconvinced, a trial at a lower resolution may be worth considering. This may be most directly done one of two ways: 1) By changing the capture settings to JPEG Recorded Pixels = "M" (14Mpx), or 2) by resizing a series of full-resolution (6016px x 4000px) captures to match that of the K-30 (4928px x 3264px) using the software tool of choice. If the lower resolution shots are more acceptable, the extra resolution is the cause of the discontent.
