In some respects, the most unusual aspect of Sigma’s 105mm macro is its cost. Following a strategy it has pursued for several years now, Sigma continues to price many of its newer lenses at or just below camera makers’ equivalents—unusual for a third-party player, which usually hold prices down. This lens, for example, has the dubious distinction of being one of the few Sigmas that’s more expensive than the competition. About equal in price to the Canon ($996, street), it costs $70 more than the Nikon ($900, street). Even more surprising: You have to shell out $480 more for the Sigma than for the sharper Tokina f/2.8 1:1 macro. Will this strategy work for Sigma? We’ll see. Either way, Sigma SD1 owners just got themselves one heck of a fine portrait and close-up lens.
