K20D - image quality issues.


Link Posted 25/07/2011 - 10:07
I have just got a K20D with 18-55 DA WR lens.
Not changing anything on the camera since I bought it (second hand), I have shot few pictures yesterday and I noticed that images look very saturated and almost over processed like.

Other thing is, is it possible that 18-55 DAL is sharper than 18-55 DA WR?
This is my impression so far.

Have anyone had any problems with K20d image quality or lens sharpness problems?

Have you tried changing the custom image settings? Try 'natural' and see if that is more to your taste. Or try shooting RAW

The 18-55 lenses are based on the same optical design, but different lenses may vary because of... well I suppose it's poor quality control!

The first DA 18-55 is of poorer design but the DA 18-55 MKII, DA-L & DA WR share the same optical design with the WR having new coatings.
So the WR could be ever so slightly better because of the coating.

Also for JPG's set the sharpness to either 1 or 2

I have noticed quite a few people complaining about the WR lens.
I have the Mk2 which should be the same optically and it is

Pentax K-1 + K-5 and some other stuff

Images looked good on the back screen. It is only when I looked at them today on the monitor they look over saturated and heavily processed. I am going to do a comparison between my k100d v k20d and two lenses DAL and WR.
All with default factory settings. That should give me some answers as to which one I should sell (preferably k100d + DAL although I love them both).

Have you calibrated your monitor so not then you can't judge your photos on that.

I havent, but based on the photos from k100d which looked on screen identical to printed I assume the monitor is ok.

If it's a used camera it might be worth resetting the camera to factory settings if you have not done so already and start from there. I did that with mine and tweaked the jpeg settings until I was happy. I also use the 18-55 WR and find it performs very well.

The 18-55 WR lens performs very well for me too, most of my images are taken with this lens.
