Hello jim, With my K10D, when I put on a pre 'F' lens, you can put in the focal length for SR purposes. I have found that whatever focal length is entered is the focal length recorded for the shot. So you can get some idea what lens you used from that.

It's nothing to do with Windows.

I just ran your program on one of the first files I shot with K10D and it showed the Tamron lens id properly. So, everything is cool and working, and obviously it is only a matter of proper software to decode the info. I owe you one ;-). You're welcome. It was partly your problem with the lens ID that prompted me to take another look at the file formats, and to add the text decoding of the Lens ID field. I've learned a thing or two about DNG file formats, as well as a few more things about Pentax private tags. It also looks as if there might be a few bugs in the lens name table (which wouldn't have been spotted so easily if I hadn't incorporated the feature). All in all, a win for everybody. You get a handy little utility, and I get motivated to work on the problem again. Now -- about that compression scheme in the K10D PEFs ... :-) If there is anything I can do to help programming wise, testing or otherwise please be sure to let me know (off list). The utility is more than handy :-). Boris -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

Good. I thought I knew how to write platform-independent portable code by now, but it's nice to receive independent confirmation. I was pleasantly surprised that it supports K10D compressed PEF, as well as uncompressed AND compressed DNG files! The compression only affects the layout of the actual raw sensor data, not the metadata, so that really shouldn't be too much of a surprise; ShowTags is only looking at the metadata. I haven't yet looked at a compressed PEF from the K10D, but I suppose one of these days I'll have to see if I can reverse-engineer their compression algorithm. But that can wait until I want to play with the actual image data. One thing I haven't checked is whether I got things totally right for PEFs from the K10D. The low-numbered tags in the MakerNote will be fine, but it's possible that I got the data offset wrong. Could you take a look at the BlackPoint/WhitePoint tags (tag codes 512 and 513) in one of your files, and see if they look reasonable? The BlackPoint should be an array of four small numbers (either zero or 127/128), and the white point should be four numbers somewhere around 8192 (except the first one is more likely to be something like 12000).
