You can find a list of all lenses that Pentax writes to the exif file and in dx0 module manager which lenses they have a supporting module for. If a tag is read only or incorrect for whats required exiftool will tell you.Īnd as it happens thats enough to convince dx0 that you were using that lens on that body. Its the sametag switch as for a read but ="new tag value is wriiten in quotes" Ok now that isn't supported by dx0 but what module might be close?Įxiftool -LensType="Sigma 24-70mm F2.8 IF EX DG HSM" yourphoto.dng Lens Type : PENTAX-F 28-80mm F3.5-4.5 or Sigma or Tokina Lens This redirects the output of exiftool to a text file 'focus.txt' this text file you can run a find on later and e.g find none and you might get told it occured 4 times and you can go to the list and there will be a photo filename associated with each case of 'none'. So not in focus at any focus point of course its a plain of focus so something might be on that plain but it's likely this is a bad shot unless you focused and recomposed. It helps to know where the camera thought it had focus. There is 1 at each intersection the middle rectangle has 1 halfway along each side if you draw a cross between the intersections you get the centre focal point and the two outside ones are level with the centre point and in the mid point of the 2 rectangles left and right of the centre rectangle. Now thats quite handy there are 11 focus points on most Pentax camera's and if you put a rule of thirds grid on top of your photo so cd into a folder with photo's and type that and you will get the focus points used.

it means current directory and exiftool will run on every file it finds that it knows how to get exif information from. This is a useful one for pentax users but first lets explain the. If you don't use the -s switch you get expanded names
This produces a list of all tags and values in the file.
It's a commandline toolĮxiftool -s yourphoto.dng or jpeg or whatever. Exiftool is an incredibly powerful metadata editor /extractor it works on more than just photographs.
