SIGMA: Ohsone's Anecdotes
Ohsone's Anecdotes
Ohsone's Anecdotes is SIGMA's closest counterpart to Nikon's long-running series: numbered product tales written from an engineer's perspective. It mixes individual-lens development stories with multi-generation histories of 28mm primes and ultra-telephoto lenses.
SIGMA's current English pages identify the episode number but do not display a publication date. The list therefore follows the official publication sequence, newest episode first.
