OK - I have struggled to find a suitable way to make the files available while minimising my and your exposure to spam and malware. I have just put two sample DNGs on Dropbox and shared it to your email address. That site does not appear to have the option to make files publicly available. Let me know if there's a better way to do it. IMGP0094.DNG is the one which prompted my original comments and questions IMGP0161.DNG is another in which the EXIF records 0 for the focal length. The behaviour is similar but the correction applied when K7 is set as camera (and lens left as A series) creates a severe barrel distortion. Just another data point if that helps. By the way A series is an entire series of lenses so really it should not attempt a correction without knowing the actual lens model. I am still trying to calibrate the lens.
