Nikon and Sigma Lens Replacements

(1/4) > >>

mklass:
Here is a code replacement file for Nikon and Sigma lenses that I use. This will replace the lens description interpreted by PM from the Exif, with a more complete description closer to the manufacturers own.

I use the {lt} variable to place the lens description in a IPTC field that I would not normally use anyway. (such as Source, Special Instructions, or one of the Supplemental Category Fields)

Hi, for what is this useful?

mklass:
If you want to record more descriptive information about your lens in the IPTC data other than what is recorded in the EXIF info and interpreted by Photo Mechanic.

For instance: Photo Mechanic reports the lens as "AF Zoom 300-800mm f/5.6D". The code replacement will take that data and translate it into: "300-800mm f\5.6 DG HSM Sigma" based on the entry in this code replacement file. You can make the replacement text anything you want, but I use the manufacturer's lens description, plus the manufacturer's name.

For my purposes, I place the \{lt}\ replacement variable in the "Source" IPTC field, since I don't use that for anything else.

marita:
Nikon and Sigma stabilized lenses compared in the field.  Their use in action and low-light photography is admittedly limited by their f/5.6 apertures and lack of fast, on-lens focusing motors.Nikon countered with the 80-400mm f/4.5-5.6 ED VR AF Zoom-Nikkor stabilized lens.  Not to be left behind, Sigma introduced its own stabilized 80-400mm f/4.5-5.6 EX OS lens in 2002. Nikon and Sigma received excellent scores of over 94 percent stabilization success within the three-stop improvement claimed in product brochures. In both cases,the small number of images not fully stabilized could potentially be corrected to newspaper-quality images with blur correction filters.
