Originally posted by house Those look very nice! Mine do not consistently look that good. You are however using a K-7 rather than a K-3 II, I'm not sure how big a difference that makes. Looking around the internet for full size 24mp samples I've found that quite a few suffer from soft corners.
Oh, thank you for your praise, house. Since 2014, my DA15 has also seen a fair amount of use on my K-3. If anything, the lens does even seem to fare slightly better on the 24MP sensor, possibly because it can play out more of its centre sharpness and rendering characteristics. Here's a selection of shots from North Holland taken with that combo (

To be fair, I know perfectly well there're sub-par copies out there, and even what I take to be a good copy of the DA15 has occasionally proved a quirky beast in my hands (perhaps more so with distant corner detail?). My shots were processed to taste in DxO PhotoLab, which has an option for offsetting corner softness, but I tend to be fairly subtle in my post-processing approach. I can only say that I have been mostly pleased with the output of my DA15, in fact, more than with any other wideangle I've owned, but other people's mileage will vary.
Does this mean I wouldn't want to add the upcoming DA★11-18 to my kit if I could afford one? Certainly not.
