In Case You Weren’t Fully Aware of Just How Stupid I Am…

Kendo master next in line for his match

If you don't know me personally you may not have a good grasp of just how stupid I am, but today's story
should fill you in plenty.

Online reviews for Sigma's new 50mm f/1.4 “Art” lens have been universal
in praise for its quality without respect to price, made all the more
amazing that its price is ¼ that of lenses of comparable quality.
I've not had good luck with Sigma in years past (as reported here and here), but all the
stellar reviews made me give them another try.

Yesterday I ordered it on Amazon Japan, and it arrived today just as I
was about to head out to photograph some kendo (“Japanese
fencing”). It wasn't the best focal length for the situation, but I used it here and there throughout the day.

Prior to loading photos into Lightroom I have to pre-process the files to fill in missing lens details that
Lightroom doesn't let me edit after the fact, such as replacing the
“0.0 mm f/0.0”
that the camera puts for my favorite non-CPU lens with a more descriptive
“Voigtländer 125mm f/2.5”.
With the new 50mm lens, I wanted a full description so as to differentiate it from other 50mm lenses
I might use, so I needed to update my pre-processing program to fill in something like “Sigma 50mm F1.4 DG HSM”.

Updating my program to handle the new lens involves finding out exactly what data the camera writes for it,
then mapping that to whatever I want to change.

It's at this point in the process (after ordering the lens the previous
day, receiving it today, testing it, and then using it throughout the day)
that I realized I'd ordered and received the 35mm version, not the 50mm
version.

Doh!
