Hmmm,
Sigma 35mm 1.4 at $899
Canon 35mm F2 IS at $849
Canon is getting truly ridiculous with their prices.
It's worse where I live.
Sigma & Samyang lenses cost exactly the same as in the U.S. (= convert to local currency, add sales tax, and it's the same +- $25), while Canon lenses have a significant sum added, regardless ot who imports it.
E.g. the EF 40mm f/2.8 is priced (exclusive of sales tax, converted back to US$) $219 - those $70 are a 45% markup. The EF 8-15mm f/4 is priced $1695, or $387 (or 23%) markup.
The price of the Canon 35mm f/2 is a bit cheaper than the Sigma in the U.S., but will be significantly more expensive around here. I use fast lenses shooting bands in low light situations, so I prefer another f/stop to IS. If I decided to spend that much on a 35mm lens, the Sigma would win my cash (joining three other Sigmas in my bag), just because Canon's (and Canon's importers') pricing policy.
