KP image quality?

I am a rather unhappy KPowner,I was very happy wutk my K30 untill it fell on the floor. My first Kp war replaced after miles and miles troubles with AF and batterylife,
The second is better, but the average IQ is not on par with K30. The maximum IQ is marvellous, the minimum is awesomme. I wonder if it is caused by shutter vibrations as described in another thread. Can someone with knowledge to KP give an answer?

Comparison shots with exif information? Settings? You need to support your statement about the KP having worse IQ with some images and how they were taken for anyone to offer suggestions. There very well could be an issue with your camera since my KP images are noticeably better than my K-50.
Even if you just post links to comparisons on flickr there are lots of folks here who can offer help.

"The maximum IQ is marvellous" ...."the minimum is awesome" ...."the average IQ is not on par with K30" .....

You need to make another attempt to explain these three statements, rephrase them to make more sense.

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.

It could be the extra pixels. It could be the lenses need calibration with the camera. A lens might have been +1 on the k30 and +5 on the kp. The +1 would hardly be noticable where +5 would. So have you done focus adjust with your lenses?

I'm perfectly OK with someone struggling to get the most out of any of the 24Mp sensor bodies but this seems just plain user error. My K-5IIs already blew the K-30 out of the water, my own current K-70 and my daughter's K-3 blow the K-5 II series as well as the K-30 (which my daughter owned prior to the K-3) out of the water. From what I've seen from others, the KP is on par with the K-70 at lower ISO values and surpasses it from ISO1600 upward.

This is most likely just operator error or lack of quality glass.

You cant compare 100% crops between a 16mp and 24mp sensor as the crop of the 24mp will be of a smaller area and reveal any weakness in the lenses your using. The other thing is that you need more sharpening as the detail from the 24mp is finer than the 16mp when viewed at full size. All the lines are smaller and give you the impression of less sharpness, even though there is more detail.

Not my experience, though much may depend on the lens being used. Detail rendered is detail rendered. If the OP is shooting with the kit lens from the K-30 or even the new DA 18-50/4-5.6 a little more sharpening may be needed to compensate for detail not rendered.

The KP, in most shooting scenarios, mops the floor with K5 and is nipping at the heels of the K1. YMMW.

I'm thinking of going from the K-30 to the KP.


Does the 18-135mm work well with the KP?


Would getting the new PLM 55-300mm make sense?

Good thought!

I can't say since I have not used one.

Definitely a good combo with the KP.

I think it works very well on the KP.
It combined with my DA 300* are used about 90% of the time.
