Title: Lens ID - Sigma 120-300mm f2.8 ex dg apo hsm - different
Post by: Kronk on August 25, 2010, 09:06:37 AM
Hi,

Just a FYI / FWIW
A Usenet Newgroup aquaintance resently purchased:
http://www.sigmaphoto.com/shop/120-300mm-f28-ex-dg-apo-hsm-sigma
for his Nikon D300

I noticed it didn't match the data in your "Nikon.pm" file so as to insert the Lensname
(Nikon.pm)
    '7A 54 6E 8E 24 24 4B 02' => 'Sigma APO 120-300mm F2.8 EX DG HSM',

Exiftool_GUI, PhotoME, and ExifTool list it as unknown but shows:
   Unknown (FA 54 6E 83 24 24 02)

(ExifTool -h -w .html filename) [something like that]  does question if it is said lens.

Anyway, just a diff of the first HEX value - FA vs 7A
and I thought I'd let you know.

Thanks for this report.  If you have a sample image available I would like to have one.  You can post it here or email it to philharvey66 at gmail.com.  TIA if you can do this.

Hi Phil,
Yes, just a JPEG though.  filename "AUG_6049 DS1024 NX2-60.jpg"  (211KB)
I have yet another somewhere ..though, when that was posted it was said that it was used w/ a Sigma APO 1.4x TC.
Originally, I'd thought that somehow it, in itself was causing the HEX value change.  Then, he posted (for me) one w/o the TC.
It had the same HEX values as I've posted.  Soo... me thinks its an updated model of said lens.

You're welcome and thanks ..and just a BTW.. it seems there was no problem in doing this to my "Nikon.pm"  I copied the already listed line (w/the "7A") for the lens.  Inserted / Pasted it in just below that entry & changed that first value to "FA".

Hmm, I think I did the same for PhotoME's "Nikon.xml"  ...can't remember, now, if that worked.  ..Just checked it again YEAP! it works.
