This is for the:
HD Pentax-D FA 645 90mm F2.8 ED AW SR Macro

Camera make:
Pentax

[Phil Harvey]

Thanks!  I've been looking for a 645 90mm sample for a while now...

Just one thing: I think your file was corrupted because the first number should be 13 (and the 2nd I'm guessing should maybe be 20).

Where did you find the sample?

- Phil

Edit: I haven't added this LensType because I think the value is incorrect.  Please check again with a sample straight out of the camera.

Edit: 2 months later and I have finally found a sample.  The LensType is "13 20" as I suspected.

Hi Phil,
just an idea about the Sony E-lenses "LensType", before you release the next Exiftool version:
Maybe it is not a good idea to use the same name, as the values in this 0-31 range are already used by Minolta A-mount lenses.
So I would prefer to use an alternative name,
or maybe combine as int16u with the '128' value at the next offset, to give unique values in the 30.000 range ?
Regards,
Jos

[Phil Harvey]

Hi Jos,

I called it LensType so that it would funnel into the Composite LensID tag, which is the best tag across all make/models for determining the type of lens.

The overlap in values between these tags isn't a problem for ExifTool -- this happens with many other tags (as you well know).  When writing, as long as you write by lens name, then there isn't a problem.

The int16u idea is a possibility, but I'm a bit nervous about this since I don't know what the 128 is for.

- Phil

Edit:  What about arbitrarily adding 1000 to the values?  There shouldn't be any overlap with values of the other LensType tag if we do this.

[JosR]

Hi Phil,
Normally overlap is not a problem, but I have a batch file to add lens information conditionally depending on the LensType:
e.g. call exiftool.exe -Exif:LensModel="24-105mm F3.5-4.5" -if "$Sony:LensType# eq 24" *.*
And now there would be two times a LensType 24:
    24 => 'Minolta/Sony AF 24-105mm F3.5-4.5 (D) or Sigma or Tamron Lens',
    24 => 'Sony E 10-18mm F4 OSS',
If I would run this batch file on NEX images, incorrect lens information may be added...

Indeed, I don't know what the 128 means, so adding 1000 might be good solution for now.

and btw., LensSpec as input for the Composite LensID appears to provide the most accurate info for all the E lenses.

Hi Phil,

I have a missing Lens data for a Canon EOS 6D, could you please add it!? It should be possible to seperate it from the already existing Canon and Sigma lens by focal length and f stop.

Thanks a lot in advance!
