Notes

Native Sony E version from Sigma's nine-prime E-mount launch, not an MC-11 kit. Heavier than the DSLR original because the mount adaptation is built into the barrel.

How we compute each section

References on each chart link down here. More notes will land as new sections grow.

1. Price history

#1.1 · Grade buckets
Each seller publishes their own raw condition labels (e.g. "Excellent+", "Like new minus", "Bargain"). Those are normalized to a small bucket set: mint, excellent, good, fair, poor, and unknown. The "Latest pricing by source" table above shows both the raw label and the normalized bucket so you can audit any individual mapping.
#1.2 · Missing days
A point is only drawn on a day when a snapshot existed for that (source, grade) pair. Lines connect across gaps so a series with sparse sampling still reads as a single trend, but absence of a point does not mean a stockout: it means we didn't see a listing at that grade that day.
#1.3 · Color encoding
Hue carries the source: terracotta = mpb, sage = keh, cobalt = B&H, honey = ebay. Lightness within a hue carries the condition: darker means a better grade (mint and excellent are darkest; poor is lightest). The dashed ink line is launch MSRP, included as a reference even though it isn't a price observation.
#1.4 · Shipping
Every price on this page is the item price, the number the seller puts on the listing. Where a seller quotes shipping we show it underneath as a separate line and add it up for you, because on used marketplaces it is not small: a lens listed at $189 can carry $74 of shipping, which is 39% on top. Dealers (mpb, keh, B&H) ship domestically free or flat and we do not ask them for a figure. Where eBay quotes nothing the row says so, because some listings calculate shipping from your address and we cannot know it; on the 2026-08-23 crawl that was about a third of eBay listings, and most of them were US sellers rather than overseas ones. Price history charts the item price throughout, so a series stays comparable to its own past.
