DA L 55-300 Unknown in Lightroom 3.3

My DA L 55-300 does not show the lens model in Lightroom 3.3. My DA L 18-55 and FA 28-200 both show up fine. Can anyone say if this is a Lightroom issue or a problem with my lens?

Anyone with a DA L 55-300 that does show properly in Lightroom?

I just checked my DA L 55-300mm photos in Lightroom 3.0 and they show up as unknown as well.
the 18-55mm DA L shows up correctly, but neither my Sigma 100-300mm F4 or my Sigma 10-20mm show up fully. the 100-300mm just says Sigma Lens, the 10-20mm shows Sigma or Tamron Lens.

I don't have the DA L 55-300, but my DA 55-300 is recognized by LR 3.3 for MacOS

My DA55-300 only shows up in Pentax Photo Lab, not in Pentax Photo Browser, Photoshop, or any other software I've used.

This is a software 'problem' in the software that one uses (e.g. LR). The lens info in the EXIF is just a number; the software must translate this number to a text, but if it does not know the number, it will not be able to do so.

The writers of these softwares should be lynched. It's so easy to make a little text file where one can add the lens ID and the text. Or add a menu option to edit the (lookup) table.
