Camera Calibration - Image EXIF without Focal Length data - Agisoft Lens

[sofamio]

We use a  width angle lens, with adapter, in the Sony NEX5. So the image EXIF not carry the focal Length data. the doubt in about the process in Agisoft Lens, is possible enter manually the Length data, before generate the calibration parameters?.

I believe under Tool > Camera calibration you can enter the fixed focal length in the top right of the camera calibration window.

Thats is quite good if all images have the same focal length but with a zoom lens you don't have that.
We have our own RAW to EXR process and would like to add Focal length to the EXR. It would be simple to add the meta data but the PhotoScan would need to pickup the data. Seems there is no standard way doing that but it would be very helpful to get any number over. It's a few minute programmer task to read the data. it could be formated like this (EXR has types key value pairs):
"focal length" "float" "40"
Seems the only other high quality (16bit, HDR) option is to use a LDR format and replace the image later in the process with the HDR image (needs to be exact same size to be accepted by the tool). Would would like to avoid that.
