a couple of years ago I fixed the FOV reading for Olympus cameras. Out of camera images are pretty OK now, but there is no way Hugin can support the panoply of software used to convert RAW / edit the images before they are fed into Hugin. > Focal length in generaly is handled well (except canon zoom browser > that works only well for EXIF info for canon camera files). I am not sure I understand this statement. Is there an issue with files saved from canon zoom browser when they are loaded into Hugin? > Apart of the save lens, wish there was a camera database in Hugin > where you can put the camera and multiplier for that camera and save > it. > When needed Hugin can read that info and fill in the multiplier > value.The multiplier is only dependent of the camera and not the lens. The multiplier depends on what is in the file. As much as converting software can garble EXIF, it is possible that a converting software garbles the multipler as well, e.g. "converts" the focal length information to full frame equivalent or whatever multiplier it wants to write in. I don't think that recalling a multiplier value based on the camera's identification tag can be helpful. Also, most users work with a single camera and a single conversion software. Sometimes two. The effort of saving the lens (which is anyway strongly recommended, including calibration) is minimal. Getting to grip with the hundreds of camera models, EXIF-mangling software, and all combinations thereof is not practical. Yuv
