Originally posted by kjphilippona I have the K-01, K5II, K30 & K50 along with some of the best lenses Pentax makes. I am still not happy with the image quality/sharpness my cameras produce. Should I purchase the K5IIs or K3 ?
All four of the cameras you own are routinely capable of outstanding image quality with decent lenses - and you have some fine lenses. In addition to my K3 & K3II, I regularly use my old K5 with some quite old glass, and the results are excellent. I think it's very unlikely that you would notice a significant improvement in IQ with a different model. What is it that you're unhappy with in terms of the results you're achieving? Let us know what your expectations are, and where your images are falling short (some examples, at the magnification you are viewing at, would be helpful). I'm sure we can help you get what you're looking for without you needing to spend any more money.
EDIT: Some recommendations to get you started (apologies if you know all of this already!)...
- try not to shoot with the lens aperture wide open - ideally, shoot one f-stop down or more (so, on an f/2.8 lens, stop down to f/4 or smaller)
- minimum shutter speed for static scenes hand-held should be 1 / (focal length x crop factor)... so, with a 100mm lens, you want to be shooting at 1 / (100 *1.5) = 1/150s
- carry out AF fine adjustment for your lenses (there are articles here on the forum and elsewhere on the internet explaining how to do this)
- use Lightroom, Photoshop or one of the many other commercial or freeware post-processing tools to gently sharpen your final images
EDIT #2: I've attached a couple of screenshots to show the importance of sharpening in post processing... I took a quick RAW shot just now with my K5. The first screenshot shows a comparison of 100% crops of that image - on the left, with no sharpening, and on the right, with sharpening. The next screenshot shows the same comparison, but this time viewed at 50% magnification.
